Hi cornbread!

How do I do this? I already have the destination set up to do automatic ssh authentication from the machine. Which part of the script would I modify to do rsync via ssh?

I would like to understand what you are wanting to do with doing the the rsync over ssh to be able to offer you the best possible solution for your backup.
I opted
not to do rsync over ssh when I started this script as I would have had to split the script into to two parts. Part one on the mail host to sync to a backup to a backup host. And the second part on the backup host to then archive it. I found this to be error prone & complex, as well as resource intensive (network, cpu, overall time).
I am currently testing a version of the script which will, after the creation of the backup archive ssh's (beem) it over to a backup/archive host for save keeping against 2 disks failing on the RAID 5 volume over night (yes I have seen it happen with very expensive SCSI disks made in Hungary in 2002 by a big two letter computer company from the States, who could that be... I remember you! heinzg don't forget that fast
). would this be something you could use?
On a slower system that is running my backup script I still have less than 1 min down time for the service and that is when there is as good as no one on it... (I have not had a mail user complain yet
) I find this a good and save compromise for backing up the community edition server.
I would say in advance that if I was to sync to a remote host in my own LAN I would setup a rsync server and not ssh it, or even better use a iSCSI volume mounted on demand on 10Gigabit, then again a simple NFS share would also do, but the network usage, I would only do this kind of stuff on a dedicated backup LAN.... Ah to complex to be safe without support
And when it all goes wrong in production, what is it you want, yes a good old working backup that is fast and simple to restore.
My motto:
Simple is good.
please feel free to contact me if there is anything regarding this script I can help you with.
