RAID5 is fine; it's the filesystem that you need to concentrate on. Since you mentioned ext2, I'm assuming you're installing Linux. While you will no doubt get a lot of favoritism from some people on which is best, I would highly suggest that you configure a second volume as ext3 and run some tests (filebench is a good test suite). Then reformat it as XFS and run the same tests. Then reformat as JFS and run the same tests. The winner of your tests should be the filesystem you use. And no matter which filesystem you end up using, don't use the main/system volume as the same place your data goes. Dedicate a volume to BackupPC. > What is the best way to set up the RAID array for BackupPC? RAID5 if you have between four and eight drives, and RAID1+0 (RAID10) if you have more than eight. -- Jim Leonard (trix...@oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/ ------------------------------------------------------------------------------ Come build with us!
