A backup program for disk arrays. It stores parity information of your data and it recovers from up to six disk failures
Cool tool, but recommend reading the policies [0] section carefully, it did catch me off guard the first time I tried using it.
E.g. say you have /a/foo.txt and /b/foo.txt, and you run mergerfs /a:/b /merged
Now if you print or modify /merged/foo.txt, it would access /a/foo.txt because the default policy for file access is ff (first-found, as defined during the mount).
However, if you run "rm /merged/foo.txt", it would delete it from both /a and /b, because the default policy for unlink call would be "epall" (existing path, apply to all).

> 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.
