Using VSS on Windows is considered a privileged task available to users belonging to the Administrator
group. Therefore, ensure you are using a user account with enough privileges.
No additional steps are required if client is running on Windows XP or Windows 2003.
Extra steps are required, however, if you are running Syncrify on Windows 7, Vista or 2008.
These steps satisfy the restrictions imposed by UAC.
, which limits software to run under standard privileges until an administrator authorizes an elevation.
Backup jobs are typically run in the background without any human interaction and therefore, it is not practical for someone to click Yes
to the UAC prompt displayed by the OS.
You have one of two options when dealing with UAC:
- Disable UAC. Click here for more information.
- Run the backup task as NT AUTHORITY\SYSTEM, instead of the regular user. If a backup task is run using NT AUTHORITY\SYSTEM, UAC will not prompt the user for additional privileges. Click here to see how to change the user ID.
