December 31, 20232 yr Hi All, I currently have a cloud server where I use duplicati to backup all its contents to an external hard drive every night (using the unassigned devices). To have a true 3-2-1 backup strategy, I swap out this external hard drive with another one that I store at another location. Because the external hard drives are full now, I want to switch to a drive pool system that can be scaled dynamically and which can be parity protected. I was thinking of buying a QNAP TR-004U, putting it in the individual drives configuration and configuring 2 zfs-pools (1 pool for each backup drive set) in unraid. 1 pool would be active at any given time and swapped out for the other pool every once in a while. Some questions I have on this setup: Would this even work? Will unraid complain a lot when a drive pool is not active? Can the capacity of the vdev be increased similarly to current unraid drive arrays? From what I understand, vdevs cannot scale in number of drives (planned for future update), but if I were to swap out and rebuild 1 drive at a time, would that increase the capacity? Thx in advance
