We have a 6.0.4 NE Zimbra system with about 120 users. It's working fine and doing weekly full backups and daily incremental backups to a special storage device on the system.
The thing is, it's about 50% full at the moment, and does not appear to be removing old backups. I need to know what the procedure is to dump old data to ensure current backups will continue forever.
1. Can I simply manually delete the OLD backup folders on the drive with rm full-old_date_xxxxx -Rf ?
2. Will Zimbra auto delete old backups when it needs more space ?
Thanks in advance, as I can't seem to find proper documentation on what will happen when the backup drive starts to get full.
