Why each option
After completing a backup, the verification function reads the backup data and compares it to the source to confirm the backup is error-free and complete.
The Verify Backup option in Windows Backup utility performs a byte-by-byte or checksum comparison between the backup data and the original source files after the backup completes. This process confirms that no data corruption or write errors occurred during the backup operation, ensuring the backup can be reliably used for restoration.
Taking a full backup defines the scope and type of backup, but does not itself verify whether the resulting backup set contains errors.
An incremental backup only captures changes since the last backup and does not include any mechanism to validate the integrity of the backup data.
Logging off users reduces the chance of open-file conflicts during backup but does not verify that the completed backup is free of errors.
