Allow Volume Shadow Copy Service (VSS) backup. Windows systems only.


[Startup]    EnableVSSBackup=n

n is either 1 (true) or 0 (false). The default value is 1.


When EnableVSSBackup is enabled (n = 1), InterSystems IRIS® data platform supports VSS on Windows. VSS is only available on Windows. On other platforms, InterSystems IRIS ignores the EnableVSSBackup parameter.

See Backup Strategies for information about creating a backup using VSS or other methods.

Changing This Parameter

On the Startup page of the Management Portal (System Administration > Configuration > Additional Settings > Startup), in the EnableVSSBackup row, select Edit. Select EnableVSSBackup to enable this setting.

Instead of using the Management Portal, you can change EnableVSSBackup in the Config.StartupOpens in a new tab class (as described in the class reference) or by editing the CPF in a text editor (as described in Editing the Active CPF).
