Forgot to mention - the support for file revisions, though "not feature
complete" is supported in the respository. So when it is complete, your
old repository will still make old versions of files available. You
can more easily restore older versions of files when those features are
complete in the client(s).

That said, one solution is boxbackup. http://www.fluffy.co.uk/boxbackup:
(If this is in the archives I'm sorry. I certainly won't post it again.)
- Native to OpenBSD
- client/ server model with "lazy" mode backups that backup only
differences to files, so that larger files that change need not be
uploaded. Like CVS. Also supports versions, though not feature

- all communication is encrypted and compressed between server and
- backup store is encrypted/ and compressed.
- certificate authority can be offline and separate from client and
This is beta software - not feature complete, but stable enough that
many people are actually using it in production environments, *with
I use it and find it useful. you can run more than one client. I am
getting more friends to participate so that we can have multiple
servers. We can then fhave clients backup to secondary and tertiary
backup servers. That should be redundant enough for our purposes.

I'm interested in hearing if anyone has tried successfully or
unsuccessfully to use HDDs as backup media (in place of tapes).
for backups, but they do NOT work for 'version control' - i.e.
to older backups if needed.
The immediate problem that comes to mind is that HDDs are more fragile
than tapes and can lead to data loss more easily (although having each
backup written to two seperate disks [mirrored]) would alleviate
Quite frankly, the opposite is really the case (as long as the HDs are
statically mounted, possibly offsite).
Tapes have many more media problems.
You want version control? Is rsnapshot good enough granular enough?
It's basically a set of nice scripts built around rsync.
