If a Google Workspace user permanently deletes their Gmail or Drive data and later wants to get it back, you may be able to retrieve it for them. As an administrator, you can restore the user’s data from the Admin console within a date range you specify.
You can restore only permanently deleted items. An item is permanently deleted when the user's Trash is emptied. Note that if your organization uses Google Vault, permanently deleted items might still be retained in your Vault archive, depending on your retention policy.
Sharing: After you restore an item in Drive, the user needs to re-share the item for others to have access.
