What it means
This error is raised during a backup operation if SQL Server detects that a page is damaged. Specifically you get this error if the page checksum validation fails during the backup operation. The validation failure is a result of a corrupt database page. A record of the detected bad page would be added to the suspect_pages table in MSDB.
