This is the point of 'full' runs in backuppc. With tar and smb
transports, completely new copies are made, which will be linked to the
old ones only if the contents still match, and with rsync, a full
block-checksum comparsion is done.

If you are looking for an ad-hoc end-to-end check, try doing a restore
to some alternate location, then (being very careful you understand what
you are doing...) run rsync with the -nv options against the original
target and your restored copy. The -n tells rsync to go through the
motions but not actually copy anything (and is somewhat critical if you
typed your command backwards). The -v option will display the filenames
that would have been acted on without the -n. The result of this
exercise should be only the list of files that have changed on the
target since the backup run.
