- This article is a Work in Progress, and may be unfinished or missing sections.
What is the External Restore?
The External Restore is one of the Restore Modes of ZxBackup.
How does it work?
The External Restore adds to the current Zimbra server all the data, metadata and configurations stored on an External Backup.
This also applies to ZeXtras Migration Tool exports, allowing you to import domains from other servers.
The workflow of the import procedure is the following:
PHASE1
- Operation Started" notification
- Read Server Backup Data
- Create empty Domains
- Create needed COS (only those effectively used by the imported accounts)
- Create empty DLs
- Create empty Accounts
- Restore all Accounts' attributes
- Restore all Domains' attributes
- Restore all DLs' attributes and share informations
PHASE2
- Restore all Items
PHASE3
- Restore all Mountpoints and Datasources
Before you start
- If you are working on a Multistore environment be sure to have read and understood the Multistore informations page before starting an External Restore.
- If ZeXtras Backup is already initialized on the destination server, disable the RealTime Scanner in order to improve both memory usage and I/O performances.
- In order to reduce the I/O overhead and the amount of disk space used for the migration, advanced users may tweak or disable Zimbra's RedoLog for the duration of the import.
- In order to further reduce the amount of disk space used, it's possible to enable compression on your Current Primary Volume before starting the import. If you do not wish to use a compressed Primary Volume after migration, it's possible to create a new and uncompressed Primary Volume, set it to "Current" and the switch the old one to "Secondary". All of this can be done using ZeXtras Powerstore.
Running an External Restore
Via the ZeXtras Administration Zimlet
- Click the Backup tab (be sure to have a valid License)
- Click on the "Import Backup" button under "Import/Export" to open the Import Backup wizard.
- Enter the Destination Path in the textbox and press Forward. ZeXtras will check if the destination folder contains a valid ZeXtras backup and whether the 'zimbra' user has Read permissions or not.
