Yes I do!
- When assessing btrfs send / receive as a backup procedure performing multiple backups to a drive of dubious health worked great at rapidly sorting out these media: Infamous Host erlangen - #4 by karlmistelberger
Healthy drives will work flawlessly through months of testing:
erlangen:~ # btrbk -c /etc/btrbk/btrbk-home.conf stats
SOURCE_SUBVOLUME SNAPSHOT_SUBVOLUME TARGET_SUBVOLUME SNAPSHOTS BACKUPS
/home /Btrbk/btrbk_snapshots/home.* /Backup/btrbk_snapshots/home.* 82 311
/ /Btrbk/btrbk_snapshots/ROOT.* /Backup/btrbk_snapshots/ROOT.* 82 311
Total:
164 snapshots
622 backups (164 correlated)

- Balancing, scrubbing and adding/removing devices of a btrfs partition are great too.
