SQL Server error 3125

SQL Server raises error 3125 at severity 16, which marks a problem with the query or data that you can correct.

The database is using the simple recovery model. The data in the backup it is not consistent with the current state of the database. Restoring more data is required before recovery is possible. Either restore a full file backup taken since the data was marked read-only, or restore the most recent base backup for the target data followed by a differential file backup.
