Bug & RFE's I Made While Researching This Draft Write Up [Remove For Course]

Introduction

  • Will you please provide a brief paragraph introduction/overview about recovering missing data in Zimbra.
  • For example: what are some scenarios wherein you need to recover missing data.
  • What is the general method for recovery?
  • How/Why is the backup environment relevant/important.
  • Remember that this won't be obvious for all audience members.

User Issues

Questions To Ask & Address Prior To Doing A User Restore

  • Can data be restored from the user's dumpster [if enabled] ?
  • Is there a copy of the data in a third party client ? [POP email client that downloaded it, for example]
  • Does the data maybe exist in another user's account ? [For example, the senders account or others in the To/CC]
  • Does the data reside in a redolog/s ?
  • Finally, restore from backups ?
    • Do I need to overwrite the existing account with the restore or should I restore to a new account name?
      • Using the option -ca [create account] and -pre restore_ [prefix to the new account name, restore_user@ ]
    • What are your retention policies and how it might determine the backup set you need?

User Restores

  • Admin Console
    • Restore/Backup
    • Redirected restore : -ca -pre restored_
    • View Mail > TGZ export/import
  • Crossmailboxsearch
  • Importing Restored Data Into Parent Account

Restoring A User To A Specific Full Backup, Incremental Backup, Or Point In Time

One of the more common support issues around restoring a user account is the complaint that the restore didn't roll back the account to the desired state. Almost always, this is because the proper options were not passed to the zmrestore command for the restore to stop at the desired time frame. If you don't give the proper options to zmrestore, it will restore the account all the way to the most recent redolog operations on the server. For example, it replays the delete operations that caused the user to request to restore in the first place.

You MUST use the -lb [full backup label name] option when your trying to restore anything that ISN'T meant to include the latest information for the mailbox. The -lb argument should specify a full backup that took place prior to the time of the backup you wish to restore.

Find Out What Backup Session Labels You Need First

To find out what backups are associated with a particular account, you would do the following :

zmbackupquery -a user@domain

You'll want to note what is the first full that occurs before the point in time you want to restore. And then the incremental that follows right after your point in time.

Backup labels (-lb) for fulls for a particular user can be found by doing :

zmbackupquery -a user@domain --type full

Backup labels (-restoreToIncrLabel) for incrementals can be found by doing :

zmbackupquery -a user@domain --type incremental
Command Syntax Example For Restores On The CLI

Example to restore ONLY the data in the full backup session and stop :

zmrestore -a USER@DOMAIN.com -lb full-20080726.050017.306 -rf -ca -pre restore_

Example to restore only the data in the full backup session and all the incremental data after the full to a specific incremental label and stop :

zmrestore -a USER@DOMAIN.com -restoreToIncrLabel incr-20080731.060007.644 -lb full-20080726.050017.306 -br -ca -pre restore_

Example to restore to a specific time and stop :

zmrestore -a USER@DOMAIN.com -restoreToTime 20080801011800 -lb full-20080726.050017.306 -br -ca -pre restore_


Important Options You Might Want Or Need To Include

--ignoreRedoErrors : If you attempt a restore and you see an error about problems related to playing the redolog, you'll want to run the restore command again and include this option.


--skipDeletes : Please see http://bugzilla.zimbra.com/show_bug.cgi?id=31824#c5 for details on this.


-t /path/to/backup_dir : If you are restoring from another backup directory besides your current default path.


Variables that are asking for TIME rather than LABELS should follow this syntax (from zmrestore --help):

Specify date/time in one of these formats:

    2008/08/06 09:55:50
    2008/08/06 09:55:50 572
    2008/08/06 09:55:50.572
    2008/08/06-09:55:50-572
    2008/08/06-09:55:50
    20080806.095550.572
    20080806.095550
    20080806095550572
    20080806095550

Specify year, month, date, hour, minute, second, and optionally millisecond.
Month/date/hour/minute/second are 0-padded to 2 digits, millisecond to 3 digits.
Hour must be specified in 24-hour format, and time is in local time zone.

Trouble-shooting Backup/Restore Issues And Other General Questions

Backup And Restore Compatibility Between ZCS Versions

  • You can use backups from older versions of ZCS for account restores.
  • You can NOT use backups from old versions of ZCS for system restores though. Disaster Recovery restores have to be done with the same version of ZCS as the backups were done with.

Trend Data

If there is concerns about disks/partitions getting full, this command would be helpful for trending data on your server. Send support the resulting df.tar file . Note - adjust the tail command if you want more than 20 day's worth of trending data, the -n 20 option.

[zimbra@zcs806 tmp]$ /tmp

[zimbra@zcs806 tmp]$ tar cvf /tmp/df.tar `find /opt/zimbra/zmstat -name df.cs\* | sort | tail -n 20`

Directory Sizes In /opt/zimbra

Please see the following and provide the output to support. Note, even though this method is faster than doing a du it still can take awhile.

Adjusting The Disk Alert Threshold

Note - zmlocalconfig smtp_notify must return yes if you want to receive the notifications.

If you just need to adjust the disk alert threshold, then see the following:

See current values:

 zmlocalconfig | grep zmdisklog

Example adjustment:

 su - zimbra
 zmlocalconfig -e zmdisklog_critical_threshold=98
 zmlocalconfig -e zmdisklog_warn_threshold=95
 zmstatctl

To exclude a partition from the checks [example of two being excluded]:

 su - zimbra
 zmlocalconfig -e zmstat_df_excludes="/mount/point:/mount/point2"
 zmstatctl

Note, depending on your version of ZCS, you might be hitting a bug where you'll keep getting emails until a logrotate happens.

Some things to do to confirm and share with support or in bug. As zimbra

Continue to monitor your zmmailbox search results for an hour.

The Basic Information Support Needs

as root:

  • cat /etc/fstab
    • Shows us what is mounted upon boot
  • cat /proc/mounts
    • Shows us what is currently mounted and its status - you can see if a mount is read-only here.
  • df -hT
    • Lists current mounts using human-readable size information and also notes the filesystem type.

as zimbra:

  • zmprov -l gs `zmhostname` | egrep 'Back|Redo'
    • Will show us a number of variables related to backup and redologs. Also tell us if your using auto-group or the default method.
  • du -sh /opt/zimbra/redolog
    • Will might notice your redolog logs aren't rolling over, causing a possible issue.
  • ls -latr /opt/zimbra/backup
    • This is the default backup target, please adjust this path here and below if you are using a different zimbraBackupTarget value.
    • zmprov gs `zmhostname` zimbraBackupTarget
    • We'll be able to confirm permissions are right.
  • ls -latr /opt/zimbra/backup/tmp
    • This will show us if you have failed backup jobs and confirm tmp is being cleaned appropriately after the backup is done.
  • ls -latr /opt/zimbra/backup/sessions
    • This will show us what backup sessions are available and confirm permissions are correct.
    • Adjust path if your zimbraBackupTarget value is not the default path.
  • Some directory sizes in the backup directory:
    • Default path first
      • du -sh `find /opt/zimbra/backup -maxdepth 2 -type d`
    • If your using a different backup target, check that directory also. Replace /opt/zimbra/backup above with your backup path.
  • zmbackupquery
    • This should match what's in the sessions directory and it will also tell us if status of each backup and how many accts were done.
  • crontab -l | grep -i back
    • This will show use when backups are support to run and with what options they are running with.
  • zmlocalconfig | grep -i back
    • This is useful to see a number of backup options not exposed in the crontab, things related to the zip options.
  • zmvolume -l
    • This is useful to see how many volumes are being used, if HSM is being used, and if compression is being done at the volume level.
Additional Log Files Support Might Need

And send the following logs:

  • /var/log/messages
    • Filesystem issues often times are noted here and also in syslog. This might explain an interruption in the backup process. Server restarts, filesystem going full, filesystem going read-only, etc.
  • /var/log/syslog
  • /opt/zimbra/log/mailbox.log
    • The backup activity is logged here.
    • And any other mailbox.log file that would cover the event

Some Specific Example Restore/Backup Issues

NO_SUCH_ACCOUNT_BACKUP

Example errors:

Error code: backup.NO_SUCH_ACCOUNT_BACKUP 
Message: no such backup for account: Missing full backup earlier than restore-to time for account 3c397edc-c015-4d82-ae8a-1084692f8a93 
Details:soap:Sender 

Error occurred: no such backup for account: 3c397edc-c015-4d82-ae8a-1084692f8a93

Message: no such backup for account: Missing full backup earlier than restore-to time for account 3c397edc-c015-4d82-ae8a-1084692f8a93 

3c397edc-c015-4d82-ae8a-1084692f8a93 is an example of the zimbraId of a user [ user1@mail-172.example.com ] .

Confirm the current email address is mapped to the appropriate zimbraId. You'll want to search what is in ldap and the mailstores database for the exiting email address and then also search the reference files in your backups. Often times, this happens when an account was deleted and then created again. Account meaning the email address. When this is does, the new account will have a new zimbraId.

$ zmprov -l ga user1@mail-172.example.com zimbraId
# name user1@mail-172.example.com
zimbraId: 3c397edc-c015-4d82-ae8a-1084692f8a93

$ mysql -e 'SELECT * FROM zimbra.mailbox WHERE comment LIKE "user1@mail-172.example.com"\G'

$ mysql -e 'SELECT * FROM zimbra.mailbox WHERE account_id="3c397edc-c015-4d82-ae8a-1084692f8a93"\G'

$ grep -C1 3c397edc-c015-4d82-ae8a-1084692f8a93 /opt/zimbra/backup/accounts.xml

   [using the default path; /opt/zimbra/backup/accounts.xml]

$ egrep "user1@mail-172.example.com|3c397edc-c015-4d82-ae8a-1084692f8a93" /opt/zimbra/backup/accounts.xml

$ egrep "user1@mail-172.example.com|3c397edc-c015-4d82-ae8a-1084692f8a93" /opt/zimbra/backup/sessions/*/session.xml
exception during auth

Example error:

LDAP backup failed: system failure: exception during auth 
 {RemoteManager: zimbramail.example.com->zimbra@zimbramail.example.com:22}
 com.zimbra.common.service.ServiceException: system failure: LDAP backup failed: 
 system failure: exception during auth {RemoteManager: zimbramail.example.com->
 zimbra@zimbramail.example.com:22}

This indicates the ssh keys aren't configured correctly in the environment. You should be able to do the following to resolve the issue:

su - zimbra
zmsshkeygen 
zmupdateauthkeys

Note - You should also confirm that you do indeed have the ssh port available. The default is port 22. If your unable to ssh into the server using port 22, then this might be the issue. If you configured ssh to listen on a different port on this server, you'll need to adjust the following variable - zmprov gcf zimbraRemoteManagementPort . You might also have the ssh port blocked - confirm your firewall, iptables, etc is not blocking the ssh port.

LICENSE_ERROR_Message: AccountsLimits exceeded

Example error:

LICENSE_ERROR_Message: AccountsLimits exceeded

You should check your license and confirm it's valid and active:

su - zimbra
zmlicense -p

And confirm how many licenses are used: First, flush the cache on all servers for the license information. Then do the query via soap.

zmprov fc -a license
zmsoap -z GetLicenseRequest

Four lines that are generally of interest are shown below. The first two state how many one is licensed for, the bottom two show how many are currently used :

 <attr name="AccountsLimit">1000</attr>
 <attr name="ArchivingAccountsLimit">1000</attr>

 <attr name="TotalAccounts">3</attr>
 <attr name="ArchivingAccounts">3</attr>

Hands On How-To And Reviewing Of Log Events

Example of what log events are generated for a full backup in /opt/zimbra/log/mailbox.log . First, you'll see the authentication/acl request and then statements about the backup request.

Your log events will now reference Backup in them. AsyncFileCopier will start and it will give the backup session label for this backup job.

2015-03-03 20:20:01,092 INFO  [FullBackupThread] [] io - AsyncFileCopier is starting

It proceeds to backing up your accounts. I'll list the backup log events for just two accounts on this system - user1@mail-172.example.com and admin@mail-172.example.com . I'll provide the zimbraId, email address, and mailboxID information for user1@mail-172.example.com below so you can confirm it's reported in the logs correctly as well.

[zimbra@mail-172 redolog]$ zmprov ga user1@mail-172.example.com zimbraId
# name user1@mail-172.example.com
zimbraId: 3c397edc-c015-4d82-ae8a-1084692f8a93

[zimbra@mail-172 redolog]$ zmprov gmi user1@mail-172.example.com
mailboxId: 6

Now, continuing with the log events. Notice the reference to the redo log file sequence, putting the account into and out of maintenance, number of blobs and index files backed up, and the statement it's finished backing up the account. Also within the section we can see the user's zimbraId [3c397edc-c015-4d82-ae8a-1084692f8a93] , email address [user1@mail-172.example.com] , and mailboxId [Mailbox 6].

One thing to point out is the log events were mentioning the redo log sequence as being number 10 but in the redolog/archive directory there is only a sequence 9 redo log. This is because the "seq 10" is actually the /opt/zimbra/redolog/redo.log file. When the redo.log file rolls over and is moved to the archive directory it will have seq10 in it's filename.

[zimbra@mail-172 archive]$ pwd ; ls -la *.log
/opt/zimbra/redolog/archive
-rw-r----- 1 zimbra zimbra 146723 Mar  3 20:23 redo-20150303.060015.816-seq9.log

The contents of the backup session directory. I removed the sub-directories under accounts that weren't either the admin or user1 account. Notice the zimbraId is used for the sub-directory naming scheme.

Notice how the log events are soap requests and differ from the full backup above and lack the INFO [*Backup*] formatting. Important to note this if your attempting to grep for backup/restore activity. Just like with the full, it starts with an authentication/acl request and states it's starting, how many accounts found, AsyncFileCopier starting, and the label name for this backup session.

The incremental will then end with log events related to copying the redologs into the backup directory and then purging the redologs that can be deleted. This example states redo log sequence 9 can be deleted. We'll confirm it is later.

For an incremental, the account sub-directories will have ldap data saved also for each user but blobs and indexes aren't. That data resides in the redologs from the system under the redologs directory.

If you had created new users after your last full backup, you would see that there was also a full backup started as well. For example :

[zimbra@mail-172 log]$ zmbackup -i

First, see what zmbackupquery shows for a particular user in regards to the backup labels they are included in.

Now let's review the accounts/session xml files that list all the users within those particular backup sessions. The /opt/zimbra/backup/accounts.xml is the referenced to determine what is the last know full backup session the user was in. If the /opt/zimbra/backup/accounts.xml is corrupted, unreadable, or incorrect - this can cause issues with restoring users.

Also notice that it also references the zimbraId for the user at the time of the backup. If you were to delete a user and then create a new account using the same email address [user1@mail-172.example.com] that new account will have a different zimbraId and therefor the backup/restore commands will not work as you might expected because of the differing zimbraId. The zmrestore command only can take an email address for the -a option, it can not use the zimbraID.

In each backup session, there will be a sessions.xml file that acts as a reference or summary file of the backup. At the top, you'll see what version of ZCS was running and what options the backup environment had set. It will then report the final status for each user for the backup attempt against the account. At the end, there's a section in regards to errors and if any were encountered.

User And Log Events Generated

Please beware that prior backups were deleted and new backups were made on this ZCS test server. So the backup label names might not match prior examples.

For this example, I'm going to replicate a common situation that system administrators find themselves when trying to restore a user and they fail to include the proper restore options to have the restore stop prior to replaying a message that was deleted by a user. Proper examples of doing the restore will be shown afterwards.

Information on the account we'll restore:

[zimbra@mail-172 backup]$ zmprov gmi user1@mail-172.example.com
mailboxId: 6
quotaUsed: 1209

[zimbra@mail-172 backup]$ zmprov ga user1@mail-172.example.com zimbraId
# name user1@mail-172.example.com
zimbraId: 3c397edc-c015-4d82-ae8a-1084692f8a93

Example of error you'll receive if you attempt to use the zimbraId rather than the email address for the zmrestore command. This is important to note if your trying to restore an account that was deleted and then later created again and the various backups and accounts.xml file has different zimbraId's associated with the same email address.

[zimbra@mail-172 backup]$ zmrestore -a 3c397edc-c015-4d82-ae8a-1084692f8a93 -ca -pre restore1_
Error occurred: invalid request: invalid account email address: 3c397edc-c015-4d82-ae8a-1084692f8a93

Showing that we have one message in the Inbox for the user we'll be restoring and also the message id of that email :

     Id  Type   From                  Subject                                             Date

Now to delete the email from the account:

[zimbra@mail-172 backup]$ zmmailbox -z -m user1@mail-172.example.com dm 257

And to confirm it's no longer there:

[zimbra@mail-172 backup]$ zmmailbox -z -m user1@mail-172.example.com s -t mess in:Inbox
num: 0, more: false

Below is an example of a delete operation being logged in the redo.log and how to query events for a particular user with the zmredodump command. Notice the DeleteItem events at the end.

[zimbra@mail-172 backup]$ zmredodump -m 6 --show-blob /opt/zimbra/redolog/redo.log

Run a zmrestore with no other options other than the account flag and the email address of the account we are restoring. Note - this example is to show why this often times isn't what you'll do in real circumstances and will require other zmrestore options to achieve what you want.

[zimbra@mail-172 backup]$ zmrestore -a user1@mail-172.example.com

From the /opt/zimbra/log/mailbox.log we have the following log events. We see the restore request kick off and the full backup label that it'll reference as the starting point. It also lists the zimbraId rather than the email address for the restore initially.

Since we are basically over-writing the account, the account is placed into maintenance mode first and then existing data is deleted. Only after the account has been deleted will the account be restored using the backup data. Since we didn't use the -ca and -pre options for zmrestore, this account will reuse it's existing zimbraId, mailboxId, and of course - email address.

Confirm that the message is still missing from the account:

[zimbra@mail-172 backup]$ zmmailbox -z -m user1@mail-172.example.com s -t mess in:Inbox
num: 0, more: false

Confirm that the account is still using the same zimbraId, mailboxId, and email address :

[zimbra@mail-172 backup]$ zmprov gmi user1@mail-172.example.com
mailboxId: 6
quotaUsed: 0

[zimbra@mail-172 backup]$ zmprov ga user1@mail-172.example.com zimbraId
# name user1@mail-172.example.com
zimbraId: 3c397edc-c015-4d82-ae8a-1084692f8a93

Using The -restoreToTime Option To Restore Prior To A Message Being Deleted

First, let's identify the exact time the delete operation took place. From our previous examples above I already know what redo log sequence file it was logged in.

[zimbra@mail-172 backup]$ zmredodump -m 6 --show-blob /opt/zimbra/redolog/archive/redo-20150304.095303.026-seq14.log | grep DeleteItem
[000034d1 - 0000350c: 60 bytes; tstamp: 2015/03/04 04:48:18.119 EST] txn 1425452599.151 [DeleteItem] ver=1.42, tstamp=1425462498119, change=1513, mailbox=6, ids=[257], type=message
[0000350d - 0000353e: 50 bytes; tstamp: 2015/03/04 04:48:18.306 EST] txn 1425452599.151 [CommitTxn] ver=1.42, tstamp=1425462498306, mailbox=6, txnType=DeleteItem

The first line above shows me the delete request was done at "2015/03/04 04:48:18.119" for mailbox=6, ids=[257], type=message . Ids is the message id, that were already used to delete the message in the above example and was shown in the zmmailbox search command.


The example uses the time above but subtracted one from it - 04:48:18.118 vs 04:48:18.119 .

[zimbra@mail-172 backup]$ zmrestore -a user1@mail-172.example.com -restoreToTime "2015/03/04 04:48:18.118"
using restore to time of 2015/03/04 04:48:18

And to now confirm the message is back in the account:

[zimbra@mail-172 backup]$ zmmailbox -z -m user1@mail-172.example.com s -t mess in:Inbox
num: 1, more: false

     Id  Type   From                  Subject                                             Date
   ----  ----   --------------------  --------------------------------------------------  --------------
1.  257  mess   admin                 Test1                                               02/23/15 09:03

Note that this will also mean all other data or changes after 04:48:18.118 are lost also in this restored account. Normally in circumstances of trying to recovery data that a user is requesting because they delete messages and now need them recovered you would use the -ca and -pre options for zmrestore so you could then recover them and import the messages back into the existing account they have. Without the -ca and -pre , your over writing the existing account on the system.

Knowing When The -br [To Incremental] Or -rf [Only Full] Option Is Required

Pre-Steps

Let's query current backups and then create a new full and new incremental where we also delete a message between the full and the incremental.

First Example - Options -lb, -ca, -pre restore_

For the following examples, we'll include the -ca [create account] and the -pre [add prefix to new account name] . This first example uses the oldest full backup [full-20150304.082015.535 vs. full-20150306.043202.011] the account has with the -lb option. The message we just deleted, existed at the time of the full backup. We'll NOT be including either the -rf or -br option in this first example.

Then we'll review the mailbox.log events. Note the following:

  • That the log only mentions the parent account, there isn't a reference to the email address with the prefixed name.
  • Though the log will state the new mailboxId and zimbraId for the user, though:
    • "user1@mail-172.example.com (3c397edc-c015-4d82-ae8a-1084692f8a93) original mailbox id 6" vs "Restoring to mailbox id 12 for new account 016c9f7c-e2e2-4f8f-96d0-e14a4327821d"
  • Since we failed to include the -rf option, the restore continues past the full backup and goes through all the other backups that exist, hence we see:
    • "backup - Run redo operations since last full backup"
  • One of the redologs in our incremental had the delete operation for the message in question and we see evidence of that delete in the log:
    • "mailop - Deleting Message (id=257)."
  • Since we didn't include the -br option, the restore also continues past the backups and replays the redologs in /opt/zimbra/redolog and it's subdirectory, archive. Notice the reference to sequence 17.
    • "backup - Run redo operations from archived redo logs starting at sequence 17"
    • /opt/zimbra/redolog/archive/ has : redo-20150306.043322.070-seq17.log redo-20150306.043611.912-seq18.log
  • Towards the end, we'll get a confirmation that the restore has finished with some reference information again - mailboxId's .
    • "Restore finished for user1@mail-172.example.com (3c397edc-c015-4d82-ae8a-1084692f8a93) original mailbox 6 to mailbox 12"

Second Example - Options -lb , -ca , -pre restore2_ , -br

For the second example, we'll again use the oldest full backup [full-20150304.082015.535 vs. full-20150306.043202.011] the account has with the -lb option. The message we had deleted, existed at the time of the full backup but did NOT in the last incremental backup. Actually, the delete operation is within the redologs of the last incremental. For the second example, we'll use the -br option rather than the -rf . We'll also be adjusting the -pre option to be restore2_ vs. restore_ in the first example.

Then we'll review the mailbox.log events. Note the following:

  • Though the log will state the new mailboxId and zimbraId for the user, though:
    • "user1@mail-172.example.com (3c397edc-c015-4d82-ae8a-1084692f8a93) original mailbox id 6" vs "Restoring to mailbox id 13 for new account 4c99a395-2c39-46ec-8c1b-285d97d899df."
    • Notice the mailboxId and zimbraId for restore2_ is different than our first example when we used restore_ for the -pre option.
  • Since we failed to include the -rf option, the restore continues past the full backup and goes through all the other backups that exist, hence we see:
    • "backup - Run redo operations since last full backup"
  • One of the redologs in our incremental had the delete operation for the message in question and we see evidence of that delete in the log:

[zimbra@mail-172 ~]$
Third Example - Options -lb , -ca , -pre restore3_ , -rf

For the third example, we'll again use the oldest full backup [full-20150304.082015.535 vs. full-20150306.043202.011] the account has with the -lb option. The message we had deleted, existed at the time of the full backup but did NOT in the last incremental backup. For the third example, we'll use the -rf option rather than the -br . We'll also be adjusting the -pre option to be restore3_ vs. restore_ or restore2_ in the other examples.

Then we'll review the mailbox.log events. Note the following:

  • Though the log will state the new mailboxId and zimbraId for the user, though:
    • "user1@mail-172.example.com (3c397edc-c015-4d82-ae8a-1084692f8a93) original mailbox id 6" vs "Restoring to mailbox id 14 for new account d72a6d8d-8117-4a90-b8cf-f972f4af056d."
    • Notice the mailboxId and zimbraId for restore3_ is different than our other examples.
  • Since we INCLUDED the -rf option, the restore STOPS once the full backup is restored. Hence, we DON'T see the following line like we did in the other examples:
    • "backup - Run redo operations since last full backup"
  • And because it DIDN'T replay any of the redologs, there is NO reference to the following line either in the log:
    • "mailop - Deleting Message (id=257)."
  • NOR is there a reference to the following line either in the log:
    • "backup - Run redo operations from archived redo logs starting at sequence 17"
  • Towards the end, we'll get a confirmation that the restore has finished with some reference information again - mailboxId's .
    • "Restore finished for user1@mail-172.example.com (3c397edc-c015-4d82-ae8a-1084692f8a93) original mailbox 6 to mailbox 14"

Fourth Example - To Confirm -lb Label Does Matter

This example is to show that the -lb does indeed matter. Earlier examples used the oldest full we had that did include the deleted message in the account. We'll create a new full backup of the parent account, user1@ , where the message is absent and then do two restores using the differing full backup session labels with the proper option of -rf since we are wanting the restore to stop once the full session data is restored.

What Is Different Between The Parent Account And The Restored Accounts Where We Used The -ca And -pre Options [LDAP]

Below is a difference between the zmprov ga output between the parent account [user1@] and our last restore example [restore5_user1@]. Note, in our example here the parent account was created with default values and there was no customization's or changes to the defaults.

[zimbra@mail-172 ~]$ zmprov ga user1@`zmhostname` > /tmp/user1

Restore encountered redo log sequence error: Found gap in redo log sequence

Example error:

Error occurred: system failure: Restore encountered redo log sequence error: 
 Found gap in redo log sequence; missing 3899 through 3895; To avoid future restore problems, 
 discard all existing backups and take a full backup of all accounts; If this error occurred 
 during restore, try the --ignoreRedoErrors option

This error actually gives the two basic options you have when you encounter this. Depending on your circumstances, you might first do the restore using the --ignoreRedoErrors options and recovery what data you can prior to discarding the 'bad' backup sessions in question and attempting a new full backup of the users.


How-To Example - Extended Look At RedoErrors With Log Events

First, let's replicate a redolog failure situation, which can be done by moving the redologs from the /opt/zimbra/redolog/archive/ to a temporary directory.

[zimbra@mail-172 redolog]$ cd archive/

[zimbra@mail-172 archive]$ ls
redo-20150306.060015.331-seq21.log  redo-20150306.060109.166-seq22.log

[zimbra@mail-172 archive]$ mkdir /tmp/redolog-archive

[zimbra@mail-172 archive]$ mv * /tmp/redolog-archive/

[zimbra@mail-172 archive]$ cat /dev/null > /opt/zimbra/log/mailbox.log

Now that we've moved the redolog sequence files out of the redolog/archive directory path, we can attempt our zmrestore command. Note that the incremental backup label for this attempt is called incr-20150306.170810.793 . Though it fails because of the missing redologs, the backup is still created.

[zimbra@mail-172 archive]$ zmbackup -i
Error occurred: Found gap in redo log sequence; missing 22; To avoid future restore problems, discard all existing backups and take a full backup of all accounts; If this error occurred during restore, try the --ignoreRedoErrors option

Redirected Restore With No Deletes To Then Import Data From A Specific Time Range Into A Subdirectory Of Users Archive Account

This example would be the steps one might do if you discovered that the archiving service wasn't working as expected for a given date range and you wanted to populate the users archive account with the missing data. Normally, this would involve many users or all of your users - hence, why the issue about licenses is addressed.

Note, I use the following variables below but you should be replacing them to suit your needs.

  • $USER = users production email
  • recovery_$USER = the new email address that the restore created [-ca -pre recovery_]
  • $DOMAIN = the domain for the user
  • $USER-archive@$DOMAIN.archive = the production users archive email address

Determine all the necessary variables for your restore command.

  • zmrestore -a $USER
    • -ca -pre recovery_
    • -lb determine what full backup label to use
    • determine if you need to state the incremental backup label [-restoreToIncrLabel] and/or a specific time to stop the restore at [-restoreToTime]
    • determine if you need to use -rf or -br
    • --skipDeletes

For example:

 $ zmrestore -a user1@`zmhostname` -ca -pre recovery_ -lb full-20150321.050015.999 -restoreToTime 20150323000000 -br --skipDeletes

using restore to time of 2015/03/23 00:00:00

Set the restored account to not consume a normal license [notice recovery_$USER vs $USER]:

$ zmprov ma recovery_$USER zimbraIsSystemResource TRUE

Get what the archive accounts address is for the main account:

$ zmprov ga $USER amavisArchiveQuarantineTo

Set the restored account to not consume an archive license [notice recovery_$USER vs $USER]:

$ zmprov ma recovery_$USER amavisArchiveQuarantineTo ""

Create a directory to dump all the export data in. You might want to have this shared across your mailstores [that hold archive accounts] so you can then import them locally to the mailstore the archive account resides on.

$ mkdir /tmp/export

$ cd /tmp/export

Example exports out all data between a given date , adjust the account and date string below. Also, the filename that is being saved.

$ zmmailbox -z -m recovery_$USER@$DOMAIN gru '//?fmt=tgz&query=under:/ after:"4/8/15" AND before:"4/11/15"' > /tmp/export/$USER.tgz

Example of what is dumped

$ pwd
/tmp/export

$ ls
admin.tgz

$ tar zxvf $USER.tgz

Now to import the data into the users Archive account. Below example will dump the imported data into a specfic folder that will be created [I'm using Imported]. Adjust the account and filename below.

$ zmmailbox -z -m $USER-archive@$DOMAIN.archive pru "//?fmt=tgz&subfolder=Imported" /tmp/export/$USER.tgz

$ zmmailbox -z -m $USER-archive@$DOMAIN.archive gaf
