Hi, may be a helpful hint for all who are looking for a really fast method to backup the cyrus spool: during the last weeks a I tested bup [1] as an alternativ to my current backup setup based up on rsnaphot and rdiff-backup. Combining bup with lvm snapshots it's a great way to backup big mail storages with millions for files, qcow2 images or even complete partition dumps. Deduplication is working perfectly on cyrus' internal hardlinks or moved/renamed mail folders between backup cycles. The community is very warmhearted and helpful. I've found my definitive backup tools for my mailserver. Cheers, M.
