If you are running WHM you may want to use a script like this to archive your daily backups - since WHM overwrites the previous daily resulting in no daily history.

You can do this several other ways than this script - but this works fine if you watch the disk space on your server and clean things up as needed.

I don't login here much - so I will maintain the script here on ModMySite:
