We are using Symantec Backup Exec 2012 to backup a 2008 R2 server to an external USB hard drive. When a full backup runs, it seems like it's backing up all the data successfully and then moves on to verification. As soon as verification runs for about 5 minutes, the backup job fails and displays the following error:
The query for media sequence number 1 of this media family was unsuccessful.
Ensure that all media in the family have been inventoried and cataloged.
There is also another error above this one that reads:
Completed status: Failed
Final error: 0xe0000602 - A query for media on which the data set is being read is continued was unsuccessful. Ensure that all media in the family have been inventoried and cataloged.
I have cataloged/inventoried the drive and even gone so far as to format the external drive and completely remove the Symantec backup exec server and all registry entries and files associated with it and reinstall. How can I fix this so backups complete successfully?
