Hullo there,
I've just moved my backup server offsite.
The server has an nfs mounted share on my server at work, and the work server runs dirvish backup (which uses rsync), backing up to this mounted directory. I'm using an openvpn tunnel, and have specified the nfs mount thus: rw,hard,wsize=1024,rsize=1024,tcp,addr=10.3.0.3.
We messed around with remote backups quite a bit recently. We have settled on using BackupPC which after a bit of tweaking works quite well. However we are doing it the other way round (remote system initiates and controls the backup run)
I suspect dirvsh works in a similar way to backuppc . What I don't understand is why you are using rsync over nfs...this is adding overhead to the vpn connection.
We found the most efficient way was to run rsync over ssh (compression flag on helps a bit too) There should be no need to nfs mount the directory to be backed up to/from first. In your case you could just run rsync directly from server to remote machine over the vpn tunnel or dispense with the tunnel and do it over ssh.
