Need a good script to save kolab online.

[Alexander Gran]

Hi,

Im using the following combination of scripts:

rsback for / of the server.
Then stopping ldap&cyrus,snapshoting /var, starting again:
/etc/init.d/kolab-cyrus stop
/etc/init.d/slapd stop
lvcreate  -s --name varsnap --size 1g /dev/main/var
/etc/init.d/slapd start
/etc/init.d/kolab-cyrus start
mount -o nouuid,ro /dev/main/varsnap /varsnap
Then rsync from /varsnap to the backup destination's /var.
In my case that is
rsync --exclude-from=/etc/rsback/rsback.exclude --stats  --partial 
--numeric-ids -r -H -e ssh -al --delete --delete-excluded  -W -v 
hostname:/varsnap/* /backup/hostname/daily.1/var/
And afterwards removing the snapshot with
umount /varsnap
lvremove -f /dev/main/varsnap
again.

That way I have only a few seconds donwtime.
If you use OpenPKG your paths will vary, but basically things should 
work the same way.

Some people just backup selected files, like a text dump of the 
mailbox database etc. But I don't like that idea for several 
reasons:

a.) Storage is cheap. Backing up an additional GB (especially when 
doing incremental backups) costs roughly nothing.
b.) KISS. When I backup everything I cannot miss something.
c.) Restore of a complete crash is very simple. Just rsync back 
(maybe booting from CD), call grub/lilo, reboot, done.
d.) In case I need the textdump (i.e. version change) and the system 
is chrashed, I can use virtualisation or chroot to get it from the 
backup system anyway.


regards
Alex
