[Dirvish] Has anybody successfully restored a Linux OS (f.i., Ubuntu) with Dirvish?

The distinction here between backups and archives becomes
interesting, I think. We're using dirvish mostly for archives, with
the expectation that in the event of a major (whole machine)
outage, we rebuild the box and then import all our data.
As Andrew says, this is easier if you keep your working data
separate from your binaries / system data. (It also helps if you
have something like FAI and a clearly defined base build or SOE.)
This can get complex, though, so you certainly do want to do
some trial restores. On Debian you can get stung, f.e. if you
underestimate the import of the /var/lib/dpkg hierarchy.
If you're not running a 24x7 site I'd suggest you look at running
your servers inside VM's (pick your poison) with perhaps weekly
snapshots and daily/hourly dirvish runs. This is what I'm looking
to do with our office file server. This brings me back neatly to
the importance of distinguishing between backups and archives.
