[SQLSTATE 22001] (Error 8152)Unable to open Step output file.

Hi,

I have configured the backups from our SQL Server instance to tape directly with out storing in the local drive, so that the disk space allocated for storing the backups in the local drive is saved. 

but i end up with the below error.

Executed as user: CORP\devsqlservice. select       DATABASE_NAME   = db_name(sd.database_id)      from       sys.databases sd      where         -- ONLINE      sd.state = 0        and sd.is_read_only = 0      group by sd.database_id      order by 1 [SQLSTATE 01000] (Message 0)  String or binary data would be truncated. [SQLSTATE 22001] (Error 8152)Unable to open Step output file.  The step failed.

I am clueless , why i face this error, Do any one of you face such problems in backup (scheduled backups) job.
