I inherited management of a zimbra server whose backup system is in an unknown state. Looking at the manuals zimbra provides commands to perform backups at the application level which would be great but I am lacking disk space to use them.
So before I start moving things around to properly provision the VM and potentially breaking something in the process I would like to get a failsafe copy. Can I just get a verified copy (using rsync) of the /opt/zimbra directory and will that get everything that would need to be restored in the worst case?
