You would have two perfectly mirrored disked and have a crash nearly transparent (the server would continue to be up and running). Facing a crash, you would just to buy another disk, use "sfdisk" to recreate the partition on the new one and use "mdadm" to resync both harddrive, without having to halt your server (except when plugging the new HD ;)). That's a cheap but efficient and performant solution. Don't use HW raid card because they have special mapping on the disks, making difficult to work on them without having the HW card. Worst: when your HW raid card is dead, you're f'ed. <a href="http://www.howtoforge.com/software-raid1-grub-boot-debian-etch" title="Etch" rel="nofollow">Some info about it</a> My advice would be to install your server using the software RAID1 module.

The software doesn't work flawlessly. I have a Time Machine with my new MacBookAire. It DOES seem to work flawless. Of course, I haven't had to do a restore yet. YMMV, good luck, fjohn I have an account on MOZY but wouldn’t recommend. The software doesn’t work flawlessly. I have a Time Machine with my new MacBookAire. It DOES seem to work flawless.

While it's not that fast, it works as advertised. It reprotects the data after a failure, so provided that you have enough space, it's feasible for it to tolerate a double failure. You can pick them up for $350 now. I’ve been using a Drobo for a while. While it’s not that fast, it works as advertised.

I feel like we're dying for a good secondary backup solution. I did them math for S3 and it'd cost you >$70 / month to keep 500gb backed up on S3. I think what we really need is a cheap way for a group of people like ourselves to buy into a shared storage system that we host in our home for secondary backup. It could synchronize over night and have raid-5 style redundancy. Basically GFS for home users. Did I mention encryption? Sorry you're having a bad month! Unforunate.
