 The only issue is that it cannot remove existing
files in the restore target directory (think "rsync -a --delete"), so be sure
to restore to a basic OS install with nothing else on it.

I have gotten around this by touching each file in the target, doing the restore (which restores timestamps), and the searching for files that match the timestamp of when I touched the files and deleting those files. ( I actually move them to a holding directory just to be sure)  This works well and is pretty efficient because rsync already knows the timestamp as it is part of the algorithm.  There is a little i/o overhead but it is completely hidden by i/o on the server side.
 
I absolutely love BackupPC.  I ran Bacula for 2 years before this, and have
experience with several basic systems like rsync to disk and dump+tar to tape.

tape sucks.  Unpleasant in every way.  I have to use a tru64 util vdump on advfs volumes as all the tru64 restore tools rely on it (the good tools anyway).  I now do infrequent vdumps and frequent data backups with backuppc so I can restore the OS, then update that restore from backuppc.
