How do I backup individual blogs for my users on my

How do I backup individual blogs for my users on my multisite (I'm using Pro Site)? I notice that the individual users don't see the Snapshot plugin in their blog admin, only me as administrator.

Must I set up a snapshot schedule for every blog on my network? That would get overwhelming in time.

Is there a way the individual blog user can admin their own backups?

I'm just seeking the best way to allow users to be backed up. Of for users to know they are backed up.

Thanks,
Dan
