In the course of the few btrfs crashes I had on my USB backup drive (NOT the drive from my other bug report, which is an internal SATA drive) - in the last 6 months or so - I ended up having a 4 to 5 bad checksums reported by scrub. This drive is used to synchronize snapshots from my main machine, and the corrupted files are system files that are still present on the main machine. I could obviously reset the filesystem on the USB drive, but since the goal is to keep a backup history (which the main machine does not keep), I would rather avoid that. Would there be a way to replace the bad blocks using the good file on the main filesystem ? Replacing it in each snapshot separately does not look very appealing as the file is present on most of them.
