I think I understand the backup reasons now for doing the two 13TB pools. There don't seem to be a lot of good tools for doing backup of the pool so if you can backup the individual drives without any duplication then that's the way around backing up the pool. The best backup scheme that I've come up with so far is to use freefilesync on the pool. For non-pooled drives, I've been using Terabyte's IFW.

So, how does this work logistically? Maybe the following: Create a primary pool of 10TB + 3TB Create a backup pool of 10TB + 3TB Create a mother of all pools containing just the backup pool Copy all information from primary pool to mother of all pools Delete information from primary pool and add it to the mother of all pools Enable duplication on mother of all pools How does this help with backup solutions that don't like pools? Do you go down to the underlying disks themselves in the backup pool and just back them up? Right now, I have a single pool consisting of all the HDD's with pool duplication turned on. If a 10 TB HDD dies, I should still have all of my files on the remaining drives but duplication stops if I have more than 8TB of information in the pool. 10TB Drive dies: 26TB - 10TB = 16TB/2 = 8TB max of duplication 3TB drive dies: 26TB - 3TB = 23TB/2 = 11.5TB max of duplication Unless I'm missing something, it doesn't really matter with drivepool where the data resides. If duplication is turned on, I can lose a drive and still have all of my data. The bad drive just has to be removed from the pool and another of equal or larger size is needed to replace it (or multiple smaller drives adding up to the size of the drive lost). I guess I just need to stop being hung up on the RAID paradigm. What's a good backup program that works with a Drivepool volume rather than having to go to the base disks?

I've got a pool consisting of a 10TB + 3TB disk called Primary Pool. I've got another pool consisting of duplicate hardware - 10TB + 3TB disk - called Backup Pool. I essentially just wanted the Primary Pool to be duplicated on the Backup Pool in a mirroring fashion. My original thought was that I could just create a new pool and add the above pools to it and turn on duplication of the pool but the new pool didn't reflect the contents of the primary pool. So, I eventually just added the Backup pool to the Primary Pool which expanded the primary pool to 26TB and turned on pool duplication. I'm not sure that this is doing what I want it to do though. Maybe I should have just added the drives from the backup pool to the primary pool and not worry where the files ended up residing as long as duplication x2 was on. What's the "proper" way of doing this?
