Pairs each <TS>.sql.gz with a <TS>.filestore.tar.gz under the same prefix; rotation prunes both together. Backup pod runs on the same node as Odoo (podAffinity) and mounts the filestore PVC read-only — RWO permits multiple pods on the same node, so this is safe.
Restore (Tower-side) reads the companion key from S3, scales Odoo to 0, restores DB + filestore, and scales Odoo back up.
