It is, or at least was, one of the most famous German lullabies (Guten Abend, gut’ Nacht). The music is from Brahms, wo made it famous. It started as a regional folk poem tho.

We got a lullaby with that line here in Germany. “Morgen früh, wenn Gott will, wirst du wieder geweckt.”

You might want to look at snapraid. I’ve recently overhauled my own NAS and love it. It is snapshot based (so not perfect safety) but it is highly configurable and provides parity and scrubbing for corruption even with a JBOD array.

The only one that didn’t die because of my own fault (two externals and a laptop one sigh), was one of the infamous IBM/Hitachi Deathstars.
