Hello! I'm planning to deploy the Open Source Edition of Zimbra and I'm thinking about a reasonable backup strategy:
For disaster recovery I would do a full backup of the zimbra directory every day (shutdown zimbra, make lvm snapshot, start zimbra, backup the files in the snapshot, delete snapshot).
But I want to have the possibility to easily recover individual mails that have been deleted by accident and to recover whole mailboxes. To do so one possibility would be to additionally backup the boxes individually (with zmmailbox -z -m $mbox getRestURL "//?fmt=zip"). But than I would need twice as many backup space as with the above solution alone.
Perhaps it would be useful to create a second "hidden" mailbox for every user, that gets a copy of all mails, so that a mail that has been deleted in the primary mailbox can be restored if deleted. But again this would take up much more disk space than needed.
Perhaps somebody here has a good solution for me? It has to work with the zimbra open source edition.
