If you find this interesting then you might also be interested in SnapRAID: https://www.snapraid.it/

> SnapRAID is a backup program for disk arrays. It stores parity information of your data and it recovers from up to six disk failures.

> SnapRAID is mainly targeted for a home media center, with a lot of big files that rarely change.

> If the failed disks are too many to allow a recovery, you lose the data only on the failed disks. All the data in the other disks is safe.

I'm not affiliated with any of the projects.

I’ve used MergerFS and SnapRAID for my media server for about two years. Together they’re really flexible and I’ve been able to drop extra drives into the array as I’ve needed the storage. On that capability alone I highly recommend using them.

I haven’t had a failure yet but I imagine I wouldn’t be in trouble unless I lost a significant portion of my parity drives at the same time.
