EnableVSSBackup

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

Synopsis

[Startup]    EnableVSSBackup=n

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

Description

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 the Backup Strategies section in the “Backup and Restore” chapter in Data Integrity Guide 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.Startup class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
