This is why I subscribe to the 3-2-1 backup rule of thumb. The 3-2-1 backup strategy simply states that you should have 3 copies of your data (your production data and 2 backup copies) on two different media (two independent drives) with one copy off-site for disaster recovery .
So I have mine in a raid WD PR4100, then backup that to a local 14 TB hard drive to an encrypted NordLocker folder, and back that up online.
So if one of raid disks goes, swapping it out it should rebuild itself. If that does not work, I can copy all my data and behind the scenes meta data Plex server folders back to a clean raid from my local USB hard drive backup. If both my RAID and my local USB driver were stolen or destroyed, I would still have everything online.
Here is a great discussion on how to best go about finding the hardest piece of this puzzle… an online service that is affordable, has enough storage, and is secure…
