Could you explain? Like, if your house sets on fire or your computer randomly blows up you're right. But for 99% of harddrive failures, RAID is probably better than a backup.

As you illustrated, the problem is that RAID only protects against hard drive failures. There are many other reasons for data loss that RAID cannot protect against. A prime example being this thread. User error (or rogue program?) deletes whole folder of music. I'm assuming that if bas had not had the music (essentially backed up) on his iPod, that the data loss would have been permanent.

Another example is, files you intentionally delete, but find you later need/want. A couple months ago, I processed some audio files and burned some of them to audio CD for my wife for a court case, and then promptly deleted them, because I thought that was it. A few weeks later she came back to me and said, oh, can you burn some of the ones to CD that I didn't ask you to initially, because I didn't think I needed them, but now I do? Instead of having to go back and recreate all the work, I just pulled all the files out of backup, and burned the new ones she wanted.

Thats what I use TFS and Sharepoint for;

My tfs and sharepoint servers are in my raid. my docs are under source control and I can get any revision from any date time.

I don't run 'rogue' programs. . . at least not any more, since I got rid of crapple siTunes.

You used it improperly. Show me the Apple Support doc that says to run that copy/move command you did. I'll wait.

Thanks for the descriptive explanation, Bang. Faulty/unintentional user behaviour was the main issue I had in mind. If you thoughtlessly delete something on a RAID10, it's gone (omitting recovery efforts here). If you have incremental backups for the last few months, chances are you can restore your data. This is especially helpful if you don't immediately recognise the loss.

A double strategy like bas's should be even more safe, of course. But you simply cannot provide 100% protection against every contingency/catastrophe/mistake, I guess.
