Extend the time of a guest file restore session
By default, an attached Guest File Restore VMDK is available for 24 hours and then it is automatically detached. You can extend the time in the Guest Configuration page.
You might want to extend a guest file restore session if you want to restore additional files or folders from the attached VMDK at a later time. However, because guest file restore sessions use a lot of resources, extending the session time should be performed only occasionally.
In the VMware vSphere web client, click Guest File Restore.
Select a guest file restore session and then click the Extend Selected Guest Session icon in the Guest Session Monitor title bar.
The session is extended for another 24 hours.
