January 7, 200917 yr When I installed a new drive I was (by my own misunderstanding) expecting to just see a bigger raid drive. I understand now that the drives exist separately. Which is fine, so here's my question for anyone's opinion. I use my UnRaid as a backup server only. I do not stream my media like it seems most UnRaid user's do. That being the case, if I were to "mirror" one drive (by copying or syncing the data from drive 1 to drive 2) would I now have an even more secure backup? I have more than enough drive space to do so. So - can I ease my paranoid fears of data loss even more by having the data on two drives? Thanks for your input.
January 7, 200917 yr Sure, having multiple copies of the data on more drives will always be more secure. In theory, unraid should allow you to lose a drive and keep your data safe. If you have the data on two drives in the array, you should be able to lose two drives at the same time and keep your data safe. FYI, using "user shares" you can see the system as one big raid drive if you wanted, but that doesn't really sound like what you're after.
January 7, 200917 yr One thing to keep in mind if you are only backing up data that exists on another system, even if you only have the data on one drive in the unraid array, in order to actually lose your data, you would need to lose the drive in the original system plus two drive simultaneously in the unraid. That's pretty unlikely already. If you are that paranoid about your data, you should probably start figuring your offsite backup strategy as it is probably more likely something like a fire or lightning strike would take out your entire unraid and the original system at the same time.
January 7, 200917 yr Also, if you do use "user-shares" you should put the copy of your data in a differently named folder on the second disk. Otherwise, if in an identical folder, unRAID will complain about duplicate files in the disks when it tries to create a consolidated view of both disks. As already said, if you are that paranoid, do NOT rely on a second disk in the same machine. Make sure an off-site backup copy of your critical files is kept. Otherwise, one fire/flood/lightning strike/tornado/landslide/thief/disgruntled-family-member/ex-friend/hacker/computer-virus/etc... could remove all access to your files.

January 7, 200917 yr Author Thanks to all! And yes, I have thought about moving my data to an offsite location as well. I might do that and use the UnRaid server as I do more media storage. I didn't know about using "user shares" to present the server as one drive. Could someone point me to someplace I can research this to understand?
