Hi all, I built my own TrueNas server some time ago just to back up my desktop and scratch the computer building itch. To get the project off the ground I used two 8TB drives in a mirrored vdev.
At this point, the drives are getting full and the server has become so much its own thing that it needs its own back up. The data is mostly media, but aside from movies, but also a lot of difficult-to-replace/irreplaceable stuff as well.
I am trying to figure out where to go from here, but there are so many considerations that I am having trouble making decisions.
For bigger drives, i am thinking of upgrading to 14tb drives at least, but am unsure if i should move beyond the simple mirror to a configuration like RAID5. Since it is mainly just my back up, up time is not a super huge concern, so maybe mirror is still the best?
For the back up back up, should the disk configuration be as complex as the system its backing up? ie. Since I have a mirrored vdev currently, should my back up be on a mirrored vdev as well? At the same time, would it be a bad idea to use something like a couple MyBooks or large but single disks to back up the NAS. For example, getting two 24tb drives that are stored in two different places off site and alternate backing up the entire NAS to them periodically.
