Describes how to fix a SQL backup that fails with the error: Database Validation failed
If a SQL backup fails with the error Database validation failed, it is usually caused by more than one backup solution backing up the database. If more than one backup solution – including SQL maintenance plans – is being used to back up SQL databases, transactional log chains will be broken resulting in failed backups.
To fix the error:
- Disable backups with all other backup solutions
- Disable backups with SQL maintenance plans
- Run a new master backup of your SQL database.
