I scheduled daily backup on tape and it was working fine for two weeks.Last night the backup failed and threw the error BackupTapeFile::SkipFileMark: SetTapePosition failure on backup device '\\.\Tape0'. Operating system error 23(Data error (cyclic redundancy check).).

Please give me a solution

It means the tape or hardware has gone bad.

This is the probable sequence:
1. a BAK file is generated and a CRC code is generated
2. the BAK file is written to tape
3. the tape is re-read and a CRC code is generate

The CRC codes from step 1 and 3 don't match. Boom! Time to replace the tape or the tape drive or the computer attached to the tape drive.

Do a checkdb of the db to check if it has any tornpages. Tornpages might cause CRC issues with backups.

Hi there..

My problem is similar to the one mentioned above, but not the same .. ->

BackupTapeFile::SkipFileMark: SetTapePosition failure on backup device '\\.\Tape0'. Operating system error 21(error not found).

This backup job was runing fine too for a long time, and for 3-4 day its making me crazy.
The scheduled evening backup is faling, but if i run a "manual" backup it's working fine..

Any ideas?
