Hello,
The Catalog folder is located at following path, C:\Program files\VERITAS\Backup Exec\NT\Catalogs.
The contents of this folder can potentially grow to several Gigabytes in size over a period of time.
It contains following files,
1-Files having *.U01 extension.
This refer to the restore selection list.If these files are deleted then you would not see any selections in the restore tab.Then you have to re-catalog the media in the Tape drives.
2-Some temporary files with following extensions,
"*.SM"; "*.FDD"; "QTC*.*"
--------------------
You can Delete these temporary files in the catalog folder and see if the backup job runs. For more details refer this document,

Hope this helps you.
Regards
