Add disk to pool for backup only

[BjornSv]

Hello,

I'm a DrivePool user for many years and I love it. It just works!

I'm planning to add one large disk to my pool to be used a backup/duplicate disk only for some of my data on my 4-disk pool. How do I do that??

Adding a drive to the pool isn't really backing it up.  There are programs that can do that, but this isn't the way. 

If you just want redundancy, then that's absolutely possible.  The simplest way, add the existing pool to a new pool, and add the large disk to that "top level" pool.  Enable duplication on that pool, and "seed" the pool from the other pool.   Eg, do this:
