If you like the idea of RAID, use it, but it is mostly for servers that want 100% up-time. If one drive fails, then the other drive will work alone until the failed drive can be hot-swapped. At least that is the way it is supposed to work in that particular RAID mode. Of course, if the RAID controller fails, the system is down anyway. (striping is for achieving some increase in data transfer speed)
Do not use the RAID array as the backup. Have a separate regular backup to external hard drives. (or tape or CD/DVD if you wish). A good backup medium these days is a SATA hard drive mounted in one of these "bare drive docking stations" that has a USB (or Firewire, or E-SATA, or ..) interface. To physically mount the drive, you drop it in the vertical slot and press it down. To physically dismount the drive you press the eject lever on the box/device, and the drive pops up. A standard bare 3.5" hard drive fits nicely in a small bank safe deposit box, if you don't have any handier place for off-site storage. There are lots of free and cheap software for performing incremental (new, newer files) backups to media that mount and perform like disk drives. Schedulers will perform the automatic backup at any time interval you wish. Some will even continuously monitor your data directory for changed files and perform the backup "immediately." That may be a hazard, as a corrupted file could overwrite a good backup. Fred Holmes At 08:58 PM 5/10/2009, mike wrote: >From your post, you clearly have no idea who you are speaking of.
