We use IBM-TSM for this and I'm quite sure it would easily backup, say, 4x 5TB (assuming four nice filesystems on decent hardware). ...of course this depends on how much your users modify their data each day. A 2nd alternative is to don't do traditional backups at all. Go either multiple replicas (probably not what you want) or a storage system that can do cheap snapshots and keep a weeks worth of daily snapshots alive. Good luck, Peter
