Backuppc does store files under pc/HOST/ - it just uses hardlinks to
pool/cpool to facilitate finding subsequent content matches..  Other
than a startup check to see that links work which you could probably
comment out in the code, I don't think anything would break if the
links failed due to permissions or multiple mounted file systems.  You
would just see a lot of errors in the logs.  However, unless you know
that the data is all uncompressable and unique, I wouldn't rule out
the usefulness of compression/pooling.  With rsync/rsyncd xfers, you
would at least get hardlinks to identical files in different runs on
the same target. On files that exist in the comparison backup run, the
links are made directly, assuming that the pool links are already in
place.

Can you elaborate on why you need to think in terms of a separate disk
per target?  You may run into some limits on mount points if you
actually try to mount that many filesystems.

If you don't mind trying alpha code, you might want to look at the 4.0
version under development.  It uses a different scheme for pooling.
