after seeing a few threads re. RAID arrays, problems booting off them, and extra strain the surviving member of an array is put under when it has to sync a new HDD after it's (only) brother's failure, i doubt the wisdom of my original idea to set up two identical 2TB drives as RAID1 array.
wouldn't it be safer (not to mention simpler) to just rsync the simple directory tree i'm concerned about to the other HDD every 15 min or so? if either of the two HDDs fails, the other one still has the important data.
it's not my desktop, but a file server i'm putting together for my employer. the only thing he cares about is preserving the data in question. if or when one of the HDDs fails, there's no need to preserve the operating system or anything else.
Hi, I'm just a desktop "business" user - accounting, business files, etc. and have two identical 500GB drives. I started with RAID and came to the same conclusion with the hassles, then I switched to rsync. However, I just do rsync about two or three times a week. With your setup, it will probably be a wash - meaning, every time you run rsync, it has to check the whole tree EVERY TIME to see what has been updated, deleted, added, etc. which takes time for the primary drive (at least from my understanding of what is going on behind the scenes). So to run rsync every 15 minutes or so, is going to bog down the primary drive. Also, with rsync (at least with my limited knowledge of the options), if you rename a file - it deleted the old one and copies the new one - instead of remembering you only did a rename. At least from my humble opinion, you should stick with RAID.
