The problem is that you are doing an incremental backup, and files
with a timestamp prior to your last backup are not included in an
incremental backup.

You should see the file get transferred from client to backuppc a
second time, and see it stored (and look) exactly the same in the
backup tree. The pooling happens below that level.
