Last week I (unluckily) had to restore a Zimbra from a backup I took with the zmback.sh script.
While the procedure is pretty simple, there’s no clear statement on how to do it, also because support is given only on the forum post which is pretty long and not easy to scan. Given that typically when you are restoring customers and users are pressing you like hell, having easy restore steps saves you some sweating.
Just for the record, zmbak.sh provides a full backup of a Zimbra installation. This means you can restore the full installation, and not like in Network Edition a single mailbox!
