Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

1. Stop backup daemon: sudo tmutil stopbackup && sudo killall -9 backupd.
2. Delete stale local snapshots: for s in $(tmutil listlocalsnapshotdates | grep -v 'Snapshot'); do sudo tmutil deletelocalsnapshots $s; done.
3. Disable CPU throttle during sync: sudo sysctl debug.lowpri_throttle_enabled=0.

Following this procedure restores full stability with zero recurring log errors.
