Doesn't it make more sense to use ddrescue and make a filesystem image ?

I mean if the fsck makes things worse then I can restore with ddrescue.

Rather than taking a btrfs restore it's better I take an image right ?

That's pretty cool. But what happens when BTRFS crashes on me again ?

I mean, this is the reason I keep complaining that BTRFS is not stable enough.

I can't keep complaining to you or the devs each time the filesystem
crashes on me, can I.

So is this a problem of my machine/firmware or a problem in BTRFS itself ?

I am either extremely lucky or extremely unlucky if I have spotted an
error in the filesystem itself.

Apologies, I must have missed it. I think you message me around 1 in
