Ron, If you're really serious about having failsafe backup, get a PogoLinux StorageWare 3800 1.2TB IDE RAID (RAID 5 with spare). Use rsync to automatically back up your SCSI RAIDs to the 3800 (crontab). Then get an HP Ultrium SCSI tape drive to hook to the 3800. The drives run about 5K and tapes are down to about $80 per. They are advertised to hold 200GB compressed, 100GB native. You know how those advertisements are. I didn't believe it so I did my own tests at work. Using byte compacted (as opposed to compressed or bit compacted) sonar data I got 170-180GB per tape with an actual write speed to tape of 13.465MB/sec. DDS just ain't in the race at 1MB/sec for DDS3 or 2MB/sec for DDS4 (those are rated numbers, not actual). This setup would run you about 11K. I figured I'd throw this out here while we were dreaming ;) Jan On Sun, 2003-04-06 at 05:36, R Parker wrote: > Hi, > > --- Steve Harris <S.W.Harris@xxxxxxxxxxxxxxx> wrote: > > > > gotta duck and cringe. :) Guys, with my > > requirements, > > > could it be done better and for less money?
