Bug#605474: upgrade-reports: Lenny->Squeeze upgrade side-effects on backup2l



Package: upgrade-reports
Severity: normal

After upgrading to Squeeze, backup2l created a level-2 backup that
contains /all/ files to backup, instead of just the few files that
actually changed.  So something in the new version of backup2l (or bash,
or find or ls?) messes with the algorithm that backup2l employs to check
for whether files have changed (date/time/size?).

After the one oversized backup, following differential backups have a
usually small size, so the problem is only visible when backup2l creates
a differential backup against a backup that was created with lenny.  So
actually I'm seeing the problem twice: once for the level-2 backup that
diffed against the previous level-2 backup created with lenny.  Then a
week later when Squeeze creates a new level-1 backup against the earlier
level-1 backup also created by lenny.

Quite a lot of wasted disk space + bandwidth.
