That looks very neat, although I'll let some other people try it first to see if it's actually reliable (what happens if Drobo crashes?). It sounds like a good replacement for RAID, but I don't think it's mature enough to be a good replacement for backups. One advantage of backups is you can go back n days, weeks, or months to get that file you accidentally deleted. Also, with backups you aren't dependent on all of your data sitting in one peace of hardware. :-) I've been backing up my laptop using Norton Ghost and an external USB drive. Personally, I'd like a BTree-ish filesystem that automatically stores revisions of files using copy-on-write (a la my Python BList class) and frees old revisions automatically as needed (a la garbage collection). I want my computer to store and manage every revision I make to any text file ever. Thanks for pointing out Drobo!
