No worries, it’s all good! It’s basically two identical drives. The backup drive doesn’t get much use outside of the rsync process, but if the main drive fails, I am able to jump onto to the backup drive without much interruption. Before rsync runs it does a comparison and only moves modified files, so it’s not a bulk rewrite every week- just brings the target up to parity with the source. If both of these drives kick the bucket at the same time I guess that will just have to accept it as very bad luck lol, only so much I can do. But the plan is when the main drive fails, backup will get promoted to main until I’m able to backfill another drive.
