As Les said: yes it will download files again if there isn't a
matching path name in a previous backup.  As it is downloaded
it will be matched against the pool, so it won't be written
to disk.  So while there is a tranfer overhead in this case,
there is no storage (or even disk write) penalty.

Yes you are.

When rsync transfers the file list it doesn't contain file checksums
(unless you specify --checksum, which File::RsyncP doesn't support).
Also, the rsync whole-file checksum is different to the BackupPC
pool checksum, so it isn't useful for trying to find files in the
pool.
