A company is concerned about the risk of data loss due to device failure.

A common misconception is that archived data, once moved to archive storage, no longer needs its own protection; in reality, archive storage devices are still physical media subject to the same failure risks as any other storage system, and because archived data is frequently the only remaining copy of information (the source may have been deleted after archiving to reclaim primary storage space), losing the archive device without a protective copy can mean permanent, unrecoverable data loss. Applying standard backup or replication practices to the archive tier itself creates the additional copy needed to survive a device failure, extending the same data protection principles used for primary data to the archive. Increasing the frequency of integrity checks (A) helps detect that corruption or failure has occurred, but detection alone does not restore lost data; it is a monitoring practice, not a protective one. A broader disaster recovery plan (B) addresses site-level or large-scale outage scenarios and is not specifically targeted at the narrower risk of a single archive device failing. Storing multiple copies in primary storage (C) is both costly and contrary to the purpose of archiving, which is meant to move inactive data off expensive primary tiers, not duplicate it back onto them. Backing up or replicating the archive is the correct, targeted protection.
