I would agree with the Linux software RAID-1 mirror. This is what I do with a number of servers that I've set up (not just Rivendell). One of my rules for mirrored systems (and for that matter offline archives), is to use drives from different manufacturers. I know that some people don't like this, however I work on the basis that is there is an issue with a batch of drives, then you are not going to get 2 to fail at about the same time. You have 3 companies to make your choice from - Seagate, Toshiba and WD, and all of these will be from totally different factories so you shouldn't come unstuck.

Then, let 'em go until one fails. When that happens, either replace the failed drive with one in-kind, and let the array rebuild, or create another RAID-1 with a missing drive, and copy from the failed old failed array onto the new "failed" array. When that finishes, add in the missing drive to the new array, and let that array rebuild. This is mostly a technique for upgrading to a larger size in-place without down-time. If you have the drive slots, create the new array complete and copy to it in one step. Having said all that, when one of the drives does fail, expect the other half of that mirror, assuming same manufacturer, type, and age of drive, to fail within three weeks of the first. Usually, you'll have a day to get the data copied off of it before it goes, but remember I did mention that shelf backup ! My shelf backup is usually an rsync update weekly or so. -- Cowboy http://cowboy.cwf1.com Manual, n.: A unit of documentation. There are always three or more on a given item.
