Thank you guys for all your suggestions. I've read this http://acs-wiki.andrew.cmu.edu/twiki/bin/view/Cyrus/Backup article.
I'm running SLES 9 with ReiserFS (noatime,acl,user_xattr,notail options) configdirectory: /var/lib/imap partition-default: /var/spool/imap So lets say I convert my mailboxes.db to a text file like this: su - cyrus -c "ctl_mboxlist -d" > /var/lib/imap/mailboxlist.txt But next steps are very unclear: Now I need to do a snapshot of the /var/lib/imap and /var/spool/imap to make proper backup. I have a production environment so I think stopping the master process is very problematic. A) So if anyone have some scripts with the snapshot feature who can share them, it would be nice to see them here. B) Also any scripts with the minimal downtime for the cyrus are welcomed. C) Any snapshot techniques (on reiserfs) are also very interesting and I like to here them. P.S. Thank you Vittorio for your script, but you are stopping the cyrus and I think it's very problematic in production environment.

(like a normal backup, but with the archived paths in imap.list echo "starting rest of backup..." >> $tmplog 2>&1 /root/backupdir/backup_imap echo "...done." >> $tmplog 2>&1 # clean the temporary directory rm -Rf /raid/mail_backup/tmpstore/* </script> I hope you can use it...
