Tutorial on how to backup/restore cyrus

[Vittorio Muth]

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 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... If you have questions just feel free to ask.

best regards,

Vittorio
