purge backup doesn't work

Asked by Alfredo

Hi,
sbackup doesn't purge old backups. I make a full backup every 7 days (into a removable drive mounted as /media/backp) and I want to purge backup older than 15 days but they are still there.

Problem solved! From today the old backup are purged! I don't know why... probably a strange way to count 15 days?! Thanks anyway!

Perhaps unexpected, but intended.

The thing is, an incremental backup by itself is nothing; it depends on the previous incrementals and the last full backup. So as long as there are incremental backups less than 15 days old, the most recent full backup before that one, and all the intermediate incremental backups, are also kept.
