Description

This error can be caused by the following:

  • On Windows XP and 2003. This message most often means that you have run out of tape space, and the backup has stopped.
  • Faulty tapes can cause this error. Sometimes tapes may consistently show this error after backing up a fixed amount of data.
  • This error can occur when the tape drive requires cleaning, usually indicated by a flashing light on the drive.
  • The tape may be write protected

Resolution

Known cause 1 - Your backup tape is out of space

To verify this is the case, look at your backup logs and add up the number of bytes backed up. If the size of the backup is at or over the native capacity of your tape it is possible that the tape is full. The advertised size of your tape is most likely to be the compressed size, which is twice the native capacity, so a tape that has 40GB written on it probably has a native capacity of 20GB.

Note: Travan tape drives generally do not have hardware compression, so the amount of data they can store is their native capacity. For other tape drives, a 1.4:1 or 1.5:1 compression ratio is normal.

To resolve this problem, try reducing the amount of data you are backing up. You can try splitting your backup job into two separate jobs to fit on two tapes. Or you can choose to do a full weekly system backup to a removable hard drive, and do daily backups for your most important data that changes daily.

Known cause 2 - Your backup tape is faulty

Faulty tapes may cause this error so try another, preferably newer tape to see if the error recurs. If it is the same tape that always causes this error it might need replacing.

Known cause 3 - Your tape drive needs cleaning

Run a cleaning tape through the tape drive several times to eliminate the problem.

Known cause 4 - Your tape drive is write protected

Make sure that the write protect tab is set to the off position on the tape.
