I have done similar things on Linux for years and am now doing them on OpenBSD. Sounds like what you want to do can be done with a simple rsync script. OpenBSD ffs (ufs) should be stable, it has been around for decades in various incarnations. I have never noticed bit rot in this system, though I imagine it could happen if a disk is gradually going bad. That's why multiple backups help. You might want to set up a raid5 backup, as this detects parity errors. More complicated though. One weakness in such as system (ask me how I know!) is that if the NAS goes gradually bad, the errors will propagate to the backup. Using rsync without the --delete option most of the time alleviates this somewhat. Only run with --delete when the backup starts getting full and you are confident that your NAS drive is ok.
