Backing Up...

[GulfVetSAF]

OK, I have regularly scheduled backups now (using backup) to my iDisk (settings, important files etc). My question is this: Is there a way to set it up so the older backups are erased as the newer ones are uploaded? Just curious as I'd prefer not to have to go into my iDisk every back up and delete them to save space. It's really not an issue, just an inconvenience.

Thanks,
Scott
