Backup of OpenBSD to Linux box

[Bernd Schoeller]

Hi -

I have got an OpenBSD box, and I would like to create regular full 
backups of that box to a Linux server at a different location.

The main purpose of this backup is to be able to restore the OpenBSD box 
on a severe hardware failure (HD corruption, fire, etc.). If possible, 
the backup should be incremental as I am somewhat bandwidth constrained 
between the two sites.

There are a number of remote backup systems floating around 
(rdiff-backup, rsnapshot, etc.) and of course there are in-house 
solutions (dump/restore), though I don't know if these are interoperable.

Is there somebody on the list who has a similar setup and could point me 
at a solution that works for him/her?

Thanks,
Bernd
