I had my entire collection of DVDs, Blu-Rays, and HD-DVDs ripped to ISOs for playback on a NeoTV 550.

A power failure corrupted a volume on one of my storage arrays, and I lost about half of my collection.  Guess who's spending the next several months re-ripping?

I just need a little bit of sympathy right now.

I'm feeling with you, sorry to hear about your loss.
If the disc(s) is (are) still working you may want to take the use of R Studio into consideration. A comparably expensive, but really powerful data recovery tool.

If not ( ), mediadogg said it right: There's only one thing to replace a backup ... a second backup.

Sorry to hear that!

After having a string of PCs at home for almost three decades, I dread the day when I will loose some of the data.

Had a close call once; a disk drive was overheating and producing errors at accelerating rate. Managed to copy everything off the drive by having a plastic bag full of ice cubes on the drive while rescuing the data. 

I also have invested in extra drives for back up, not only for my DVD, but music cds.
I have been building my dvd db since 2000. Considering the state of the on line db and my age,
I don't think I will live long enough to rebuild my db.
I am always finding something wrong, I spend a couple of hours a day just trying get profiles up to date and consistent in content.

Cost example: In 1965 the drum that held the NASA Apollo test and lift-off data, a 15 minutes window, for the scope jockies you seen on TV, then it was out of range, cost $35,000 and held only 3,538,944 bytes. Data was also backed to tape as it was received.

They had to move the drum and idiot in charge didn't follow instructions in stopping the drum. It over heated and melted the cables going to the read/write heads. When he call Phoenix, he did not admit to what he had done. I ask him to give me bad addresses, they didn't make any sense. I friend at the site told me what he had done. I had previously been to the site and supervised the cleaning of the drum and showed him the proper procedure for stopping the drum. He was sent to the Washington DC area and got into it with the union. I understand they offered him a pair of cement overshoes.

How exactly does unRAID handles power failures?

If the system did not shut down correctly, a parity check is automatically started upon power on. Other than that, there's nothing more one can be done, this is true regardless of the technology used.

UPC's are recommended for any NAS.

All of my data is on two DroboPro units. The Drobo itself is fine, it looks like it was just volume corruption in the GPT table.  I got impatient and just blew the whole thing away, and now I'm restarting the whole re-ripping process.  I'm thinking about buying a couple more Drobos to do live backups.

Small UPS would be a good investment if all devices are connected to same electrical circuit. Even small consumer units usually filter unwanted electrical peaks. I've seen several cases where everything connected behind same fuse have toasted, including every connected USB-device.

Yes, I use a APC SmartUPS for my NAS Box.  If the power goes out, it'll shut down all on it's own.  I have to then turn it back on myself with a push of a button.  I'm a big believer in UPS devices.  I have a few them around here.  I have a number of them at work.  They are a life saver.  The last thing you want is the power to go out or even flicker while your NAS is trying to write data.

Still it's always a good idea to backup your NAS anyway.  Nothing is 100% foolproof.  Having to Re-Rip all your discs just sucks!!!  Time is Money and wasting months Re-Ripping Data is money going down the drain.
