Solution

This issue is resolved with Backup Exec 23.0 Hotfix 463014 and Backup Exec 22.2 Hotfix 311011. 
Note: Once the fix is installed on Backup Exec Server and backup exec remote agent is updated, restart BE services to reduce the size of VFFInstall.log on Backup Exec server. On the remote server, the backup exec remote agent service will need to be restarted.

 

Workaround is applicable for setups running without the above fix:

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)  Disable VFF logging by modifying the following registry DWORD values to 0

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Virtfile\Parameters\Enable logging

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Virtfile\Parameters\Max Log entry

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Virtfile\Parameters\Log Level

 

2) Change or confirm the DWORD value of "CreateDebugLog" is set to 0

HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\Backup Exec For Windows\Backup Exec\Engine\Logging\CreateDebugLog

 

3) Change or confirm the DWORD value of "Enabled" is set to 0

HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\Backup Exec For Windows\Backup Exec\Debug\Enabled

 

Note: A reboot is required before the Vffinstall.log can be deleted manually.

4) Delete the log file manually from the following path -

X:\Program Files\Veritas\Backup Exec\Logs\VffInstall.log
X:\Program Files\Symantec\Backup Exec\Logs\VffInstall.log

Or
X:\Program Files\Veritas\Backup Exec\RAWS\Logs\VffInstall.log
X:\Program Files\Symantec\Backup Exec\RAWS\Logs\VffInstall.log
