(I.e. are you comfortable recovering your machiens that way). Take your backed up /etc and data files, install a new box and see how long it takes you to get the world back. If that time is reasonable, you've got a pretty good solution, and I'd stick with it. The *VAST* majority of my systems here rely on exactly that for the system config, or frequently they are "clones of each other so I have to lose all 10 to not be able to rebuild one trivially. OTOH, if you need to do stuff like recover data files user stupidity, etc, you may want to have some incrementals to "find out what state that file was in a week ago". we do incremental type backups for this stuff.
I use backuppc for this. http://backuppc.sourceforge.net/ It is not in 3.9 ports. It was sent to me by the maintainer a while back and it runs well on my OpenBSD 3.9/amd64 backupserver. It has a webinterface and the maintainer has done a good job to run it under the present apache chroot setup :-) . I could mail it to you if you need it. You can get things restored on to a differrent machine just with the click of a button. For Linux/Unix systems you can use rsync via SSH and keep your data secure over the internet. I also use Subversion ( available in ports ) for incremental backup. Kind Regards Siju
