+### Backup (on auth-file change and each wall-clock hour)
 
 1. Push local → S3 `auths/`
 2. Copy local → CCS auth dir
+3. Create and integrity-check an online CPA Manager Plus SQLite snapshot
+4. Archive the snapshot with its matching `data.key` and upload it to S3
+
+The SQLite online backup command is required because the live analytics database
+uses WAL mode. Copying only `usage.sqlite` while CPA Manager Plus is running can
+produce an incomplete backup. Each run updates the `latest` archive and its UTC
+hour slot, retaining up to 24 hourly rollback points without unbounded growth.
