Issue

Restore- \\server\[ROOT] An unknown error occurred on device "TAPE 1".
V-79-57344-34023 - No data error reading from media.

This issue occurs only when restoring from spanned backup set. If the data selected for restore in on any other media except the first tape then the restore fails. If the data is on the first tape the restore completes successfully.

Solution



Workaround 1 for restoring needed data:

Re-catalog the tapes from which data needs to be restored using the steps provided below:

Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes
 
1.  Set the value of the following registry key HKLM\SOFTWARE\Symantec\Backup Exec For Windows\Backup  Exec\Engine\Tape Format\Use Fast File Restore to 0.
 
2.  Recycling of the Backup Exec services is required for this change to be applied correctly.
 
3.  Click on Tools - Options

     4.  Under Settings Select Catalog.

     5.  Uncheck the options "Request all media in the sequence for catalog operations" and "Use Storage media-based catalogs"

     6.  Select the required tape and run the catalog operation

     7.  Once the catalog is completed, run the restore job.

     8.  Reset the registry key covered in step 1 back to a value of 1 and recycle Backup Exec services, once restore is completed.

OR

Workaround 2 to prevent this going forward:

     1. Split the backup and create multiple jobs in such a way that only a single tape media is used for each backup job.
