Errors in incremental backups

---

Problem:

When the system performs an automatic incremental backup, indicates the following message: Finished with errors

This error occurs only when you perform incremental backups. The error message is as follows :

Found gap in redo log sequence; missing 1414 through 1446; 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

Solution:

1) During a backup, if the above error is seen, the recommendation is to move the old backups out. The directories in /opt/zimbra/backup/sessions/* . It's advised to keep them somewhere at a different location to be on the safer side and then proceed to do a full backup.

2) Another possibe cause is if the /tmp or /opt/zimbra/redolog/ is filling up. Ensure that there is enough disk space available.
