Say what?!?

I got burned too. I made a snapshot and "btrfs send" it by pipe to an xz archive. When I tried to restore, I got a CRC error (from "btrfs receive", not xz). Everything lost. There's no way to restore it now.

There could very well be bitrot in your xz archive without xz detecting it: https://www.nongnu.org/lzip/xz_inadequate.html#checking
