[How To?] Database Backup Pruning?

[RWenger]

I have weekly database backups as old as April 2011, and I would like to remove most of the older backups. A quick Google yielded neither instructions nor plugins, so if anyone knows of an existing solution, I'd appreciate it.

Otherwise, I could hack together a task and maybe make my first plugin.

If they are in your backup directory you can make a taskfile and use unlink() to delete old backups with a condition to the backup timestamp : filemtime().
