I have been reading the wiki articles regarding backup & restore. I've been searching the forums and looked through user published scripts in regards to backups.
All backup strategies inclusive the ones in the wiki basically says; "pack up /opt/zimbra, move it somewhere, in case you need a restore, unpack it". This works. But this is not a smart backup strategy.
What files under /opt/zimbra can I exclude?
Do I need to take backup of binaries which exist within the .deb/.rpm files and will be restored by a clean install before unpacking my config anyhow?
Is there some "minimal" list of files that can be backed up in order to perform a full backup of my contents?
And also, while migrating this installation inbetween versions. Upgrading one to the next. I end up with a file tree looking like:
Can these earlier versions be cleaned up? Why doesn't the install script do so? Is there any risk associated?
root@imix:/opt/zimbra# ls -1
