I never heard or seen a rollback like you are describing.
The only time Backup Exec is rolling back is if an upgrade was not successful.
As info - once an upgrade was successful there is no possibility to roll back to the previous version with Backup Exec.
Have you rebooted the server after the upgrade (3 days ago); if not and this is the first reboot after the upgrade, then I am guessing the upgrade was never successful.

Hello
I was investigated this problem
1. Upgrade end suddenly in 09-07-2021,14:29:16 with no reboot
09-07-2021,14:29:16 : Action 14:29:16: UPG_UnloadVirtFileDriver.

I would suggest to run another upgrade to 20 or even 21 and then check the situation.
After the upgrade, I would suggest to reboot the server and then run Veritas Update to install the latest Feature Pack for that version.
I am not sure we can ever find out what exactly happened but whatever it was, I would suggest to upgrade again. By this you should end up with a working system.
