A backup needs protection as well as a checksum

Your objectiveIdentify what a restore test must establish.

Understand the idea.

A backup may include more than published articles. Drafts, feedback and active sessions can be sensitive. A checksum detects a byte mismatch but does not encrypt the file or restrict who can read it. Recovery needs a protected copy, an authorized path to the key where encryption is used and a tested restoration procedure.

MAKE IT CONCRETE

A worked example.

An archive and its encryption key are uploaded together to an ordinary shared folder. The files may be recoverable, but the key placement undermines the intended protection. Separating access to ciphertext and key creates a different recovery responsibility that should be rehearsed.

Try the reasoning.

Describe a restore test using a copy: verify checksum, decrypt through the authorized key source, check database integrity and read a known article. Keep the live database untouched.

What does matching a backup checksum establish?

Carry it into practice.

Record a restore result without publishing the database, encryption key or private content.
