Hi Leon,

There is (one of many) way(s) how you can perfom a backup:

This script is only for the mailboxes (/var/spool/mail/imap in my case)and the files in /var/imap (for example: mailboxes.db)


<script>
#/bin/bash

#first do an unstable copy  (just to reduce the downtime of cyrus later)

        tmplog=/root/backupdir/tmpimaplog

        echo "start backup of imap..." >> $tmplog 2>&1

        echo "rsync of /var/imap" >> $tmplog 2>&1

rsync -a --delete /var/imap /raid/mail_backup/tmpstore/varimap/ \ >>$tmplog 2>&1


        echo "rsync of /raid/mail/imap" >> $tmplog 2>&1
        rsync -a --delete /var/spool/mail/imap \
        /raid/mail_backup/tmpstore/varspoolimap/ >> $tmplog 2>&1


#now we do an rsync to "stabilize" the backup

#shut down cyrus
echo "stopping cyrus" >> $tmplog 2>&1
/usr/local/bin/cyrus stop >> $tmplog 2>&1


#sync with rsync to get a 'stable' backup

#

rsync -a --delete /var/imap /raid/mail_backup/tmpstore/varimap/ >>$tmplog 2>&1

rsync -a --delete /var/spool/mail/imap \/raid/mail_backup/tmpstore/varspoolimap/ >> $tmplog 2>&1


#start cyrus
echo "starting cyrus..." >> $tmplog 2>&1
/usr/local/bin/cyrus start >> $tmplog 2>&1



#finally we move the whole temporary backup of the disk onto a tape:
#(requires an own script)

#do the rest... (like a normal backup, but with the archived paths inimap.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... If you have questions just feel free to ask.

best regards,

Vittorio
