Now, since we moved to Zimbra I wanted to actually have it backed up.
Small script to do it using LVM:
#!/bin/bash DATE=`date -u +%d%m%Y` echo "`date +%k:%M:%S` Backup started." # Stop zimbra, create a snapshot volume, start zimbra echo -n "`date +%k:%M:%S` Stopping zimbra... " /etc/init.d/zimbra stop 2&> /dev/null echo " done." echo -n "`date +%k:%M:%S` Creating snapshot volume... " /usr/sbin/lvcreate -L 5G -s -n vol_zimbrabackup /dev/vg0/vol_zimbrarh 2> /dev/null 1> /dev/null echo " done." echo -n "`date +%k:%M:%S` Starting zimbra... " /etc/init.d/zimbra start 2&> /dev/null echo " done." # Mount the snapshot, create a backup tarball, unmount snapshot, remove the volume echo -n "`date +%k:%M:%S` Mounting snapshot... " /bin/mount /dev/vg0/vol_zimbrabackup /zimbrabackup 2> /dev/null 1> /dev/null echo " done." echo -n "`date +%k:%M:%S` Packing up stuff... " /bin/tar jcf /var/backup/zimbra-$DATE.tar.bz2 /zimbrabackup/* 2&> /dev/null echo " done." echo -n "`date +%k:%M:%S` Un-mounting snapshot... " /bin/umount /zimbrabackup echo " done." echo -n "`date +%k:%M:%S` Removing the snapshot... " /usr/sbin/lvremove -f /dev/vg0/vol_zimbrabackup 2> /dev/null 1> /dev/null echo " done." # Cleanup logs older than a week echo -n "`date +%k:%M:%S` Cleaning up old stuff... " /usr/bin/find /var/backup/zimbra*.bz2 -type f -mtime +7 | xargs rm -f 2&> /dev/null echo " done." echo "`date +%k:%M:%S` Backup done."
