I take it "btrfs scrub" didn't turn up anything, or is that what you meant by fsck? >The OS is on a single SSD (no RAID), with some caches and busy fs mounted on >a spinning disk.

With btrfs, if there really was silent corruption, you wouldn't be able to access the file in the single disk case, so no, I don't think it actually would propagate to the backup (although perhaps you don't use btrfs exclusively, in which case it of course could). Though keep in mind that corruption can happen in a variety of ways, e.g., application-level or firmware bugs. -- Marc Joliet -- "People who think they know everything really annoy those of us who know we don't" - Bjarne Stroustrup
