Troubleshooting Tape Backup Issues in Windows NT (162972)

MORE INFORMATION

Tape Drive Is Not Recognized

The most common reason for this is a problem with the SCSI bus. Verify that the cables are properly attached to the tape drive and that the SCSI bus is correctly terminated.

Error Writing to Tape

This may be due to a problem with the SCSI bus or a bad tape. When you reuse tapes, be sure to erase them first. Format and retension the tape before reuse if you can.

Invalid Media

Check to be certain you have inserted the correct type of tape for your tape device. This may also be an indication that the tape is bad and needs to be replaced.

Skipped Files

Backup cannot back up files that are locked open by another process. If the file does not become available in 30 seconds, the file is skipped.

Close as many running programs as you can before you perform a backup. There are some third-party backup programs that allow you to back up open files.

This Set Is Compressed and Cannot Be Viewed or Restored

The backup set was created in a backup program that supports compression. Windows NT Backup does not support software compression for backup sets.

For additional information, please see the following article in the Microsoft Knowledge Base:

The Backup Set Is Not Completely Cataloged

This occurs when the catalog file on the hard disk contains incomplete information. Quitting and restarting Backup may resolve the issue. If not, locate the catalog file on the hard disk and either rename it or delete it, and then re-catalog the tape.

For additional information, please see the following article in the Microsoft Knowledge Base:

You Do Not Have Permission to Access Portions of Data. Please See the Owner or Administrator to Get Permission.

This indicates that you do not have appropriate permissions for the folder you are attempting to back up or to which you are restoring files.

For additional information, please see the following articles in the Microsoft Knowledge Base:

Catalog Information: Unable to Load Catalog Data from Tape -or- Catalog Error: Error Writing a Catalog File, Check Available Space

These error messages can be generated by trying to restore to a full hard disk. The catalog files are stored in a compressed format and need to be expanded on the hard disk at the beginning of the restore operation. You can resolve these errors by either freeing disk space on the target drive, or by replacing the hard disk with a larger drive.
