After a storage glitch, a municipal records team fears some backup objects may be silently corrupted even though catalogs still list them. What control best detects that integrity problem?
Select an answer to reveal the explanation.
Short Explanation
Checksums are the tamper-evident seal on the box. If the bits changed in transit or at rest, the seal fails even when the catalog label still looks fine. Job-success mail alone cannot catch that silent corruption.
Full Explanation
Integrity validation such as checksums or cryptographic hashes detects silent corruption that job-success messages may miss. Shortening retention or keeping unreplicated singles increases risk. Catalog presence alone does not prove bit-level correctness of backup contents.
