A bit of a side note and a bit of old man reveal, it would be nifty to have the backup system write the snapshots to cd/dvd/bluray disk. I remember working in a company that had a robot WORM system. It would grab a disc, it would be processed, take it out, place it among the archives. If a restore as needed the robot would find the backup, and read off the data. I never worked directly on the system, and I seem to remember there was a window that the system could keep track of (naturally) but older disks were stored off site somewhere for however long that window was. (Everything was replicated to a fully 100% duplicate system geographically highly separated from the production system.
