>People are using the snapshots to do backups of MySQL databases, he said, which is a test of the robustness of the feature This is exciting because db workloads are btrfs's kryptonite. The only way to avoid crippling fragmentation on btrfs is to disable copy-on-write, which also disables checksumming hence nullifying one of btrfs's main selling points. ZFS seems to handle such loads much better, and it would be interesting to see how bcachefs deals with them.
