The use of multiple computers each using RAID gives me fault tolerance AND backup with the backup being controlled via a product called CrashPlan, but could be effected via rsync/cron scripts.
I never consider mere copies as backup. While I applaud you setup for its fault tolerance, a single backup copy is a scenario that has burned me in the past such that I never rely on it any more other than as a disaster cache. Too often the bone-headed deletion or disastrous program change is faithfully replicated across the synced mirrors before anyone can detect it. Like yours, my servers and critical workstations are all raid machines. My synced copies are on similar machines (using Unison ) located is in a different city. Unison is also used by several laptops that need working caches of some sub-trees (principally for software development). But my backup consists of multiple BRU backups each stepping back in time. The nice thing about BRU (or similar) is that you can stack multiple backup copies on the same size media as the running copy due to the compression. Yeah, BRU is oldschool. Hell, I'm oldschool! We used to use tapes. They sucked. We now do our BRU backups to inexpensive disk enclosures (usb/firewire) which can be taken off line and moved off site if desired. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
