[rdiff-backup-users] --remove-older-than inconsistency? (security violation)

[Giacomo A. Catenazzi]

Hello

For remote backup, after the normal backup, I delete the older
files, with two policies 15 days, but max. 5 changes:

echo "----AAAA----"
rdiff-backup --remove-older-than 15D 
address@hidden::/home/pix-backups/orion2
echo "----BBB-----"
rdiff-backup --remove-older-than 5B 
address@hidden::/home/pix-backups/orion2


but I see "rdiff_backup.Security.Violation" in the
second case. See log at the end of the mail.

Is it a bug?

ciao

PS: reducing "15D", so that it delete old backups give
no error. Augmenting "5B", so that it should not delete
anything as still the back trace.

log:

----AAAA----
No increments older than Mon Jul 10 02:08:03 2006 found, exiting.
----BBB-----
