Hello,
This error occurs if there is not enough disk space on the volume where the Backup Exec catalogs are stored. Try changing the catalog path to a different drive from the Tools | Options | Catalogs menu.
Please refer to the below given steps to move the catalogs to another location.
1. Open Backup Exec and select Tools > Options. Under "Settings" select "Catalogs"
2. The catalog path may either remain at the default setting or be changed as needed. If the target folder does not already exist, it will be created.
3. After the changes have been made, Backup Exec will prompt for a reboot. Select Do Not Restart
4. Go to Control Panel > Services and stop all Backup Exec services.
5. Browse to the original location of the catalogs and copy all of the files that end with a .UO1 extension to the new location.
6. Reboot the computer.
7. Open Backup Exec and confirm that the restore selections are displayed.
please update us the results.
