To be able to see Shared Drives in the Status or Restoration sections, you need to have the "Backup Shared Drive Restoration & View Status" permission added to your role. An admin can add this permission to your role.
The job to sync Shared Drives between your Google Workspace and CloudM Backup runs on a schedule so you may not see your Shared Drives immediately when you first access Backup, and newly created Shared Drives won’t always show immediately either. The sync should complete within 12-24 hours.
