Well, it's not file specific. Some of those are directories.

On a per host basis you just override the system excludes and setup
the excludes for that particular host.

Well, if your backup root / backup share is literally ROOT, "/", then
your excludes should just be relative from that, i.e. "pub", not
"/pub". Remember that BacupPC is essentially "clientless" so if you
need to do more advanced excludes you need to look at the rsync
documentation, not the BackupPC documentation (other than how to
correctly put it in the config file).

Well two things here:
1. I think rsync is smart enough to skip things like /proc, /dev, and such.
2. Although it can be done, BackupPC is not the right tool to do bare
metal restores. It's designed to backup files, not file systems.

There's plenty of mailing list threads, blogs, and wiki's on how to
work around that, but that's exactly what it is, a work around.
