Right, they are the same (old) timestamp, hence they are skipped from
the new incremental backup.

Except "the system" doesn't know about the new position, because no
files have even been backed up in this new position.

That would be ideal, but is not the case.

Correct, so you have a couple of choices (detailed below)

Yes, 2 in fact.
1) Use rsync for backups
2)

Or, 3) Read the documentation that tells you that incremental tar/smb
backups will miss files with old timestamps, which usually occur when
renaming/moving files/directories, or un-archiving files. Of course,
there are other methods of creating files with an old timestamp where
this can occur as well. If it is really a problem, make all backups a
full, or use another protocol which can test for files based on data
other than just timestamp (ie, rsync)
