We run the open-source edition of Zimbra mail (5, not 6 yet) and while it's not something that we want to encourage (prevention is better than a cure), we currently have no way of backing up (or restoring) mail in the system. The Network (paid) Edition has automated backups; various user-contributed solutions exist for the open source edition.
My question in two parts:
- Does anyone have experience performing backups on Zimbra OSE? I'm particularly interested in snapshot backups over ssh/rsync (we use
dirvishfor filesystem backups), and we don't use LVM (
/opt/zimbra/store/is it's own partition, the server is Ubuntu on ESXi).
- If backup/restore on a live system is "too hard", I'm happy to settle for backing up only specific shared accounts that are never logged into directly (and hence I have the password for) over IMAP. I'd be interested in recommendations for a command-line email client that
I'm leaning towards the second with something like isync, since the mail system has over 100GB of messages at present.
