I have a script that keeps backups for a period of time... weekly fulls
for 5 weeks, monthly fulls for 12 months, and yearly fulls for 7 years.
So the delete script I had is very much needed. Cron runs my scripts
every Sunday to keep things clean.
I have a matching script that forces full backups on Fridays and the
last day of each month. BackupPC is set to never expire full backups.
The old manual delete script was great. I wish I could find it again...
I left it at an old employers site, and no longer have access.

I tend to agree.
