Network Edition 8.8.10 Upgrade - Backups "Bug"
Posted: Sat Oct 27, 2018 7:46 pm
Just a heads up to Network Edition customers of an issue we discovered today regarding backups. I've opened a support case with Zimbra just now on this. If this same situation impacted your NE environment, let me know and I'll report it on my case. That may help to get this addressed more quickly.
Recently, we did an in-place upgrade from 8.8.8 to 8.8.10. Under 8.8.8, we had been using only the ZeXtras (Backup NG) backup engine. When we installed 8.8.8 originally, we turned OFF the setting in the installer screen that sets the Network Edition backup schedule. As a result, under 8.8.8 there were no NE "zmbackup" crontab entries under the zimbra user's account.
Today we got a low free disk space alert for a mailbox server's backup partition, and upon inspection found that traditional Network Edition backups had been running from the date of the in-place upgrade to 8.8.10.
I removed the zmbackup crontab entries and purged all of the Network Edition "full-..." and "incr-..." subdirectories from the sessions folder to free up disk space. I also asked Zimbra Support to confirm that using the same target directory for both the Backup NG and traditional NE backups won't cause any issues with the Backup NG backups (I don't believe it does, but wanted to be absolutely sure).
Since the default zmbackup schedule has Full backups being performed last night, if you've recently done an in-place upgrade to 8.8.10 but are using only the Backup NG backups, now might be a good time to check your zimbra's crontab for any unexpected NE zmbackup entries, before next week.
Hope that helps,
Mark
