SQL Server error 3019

SQL Server raises error 3019 at severity 16, which marks a problem with the query or data that you can correct.

The restart-checkpoint file '%ls' is from a previous interrupted RESTORE operation and is inconsistent with the current RESTORE command. The restart command must use the same syntax as the interrupted command, with the addition of the RESTART clause. Alternatively, reissue the current statement without the RESTART clause.
