There's tradeoffs for time, speed, cost, convenience, and reliability. For a professional/enterprise solution, as I made clear (and as was hashed out with Alvin last week on the SVLUG list, discussion linked elsewhere by me), other options may be preferable. Alvin tends to work production systems. I tend to work single-user/small office systems. Fit your tool to the task at hand. > -- i think a backup system should be able to restore a suystem within > 1hr of the disk "being erased/or system went down"... Distinguish "backup" from "disaster recovery". Ideally, 1 hr is too slow, I'd like failover systems. But that's not a storage backup.

Test your solution. My scripts include a verify of each archive created, message to log.
