You can restore Office 365 sites either to the same source client or to a new destination client.
During an out-of-place restore operation of multiple related sites, the top-most selected site in the source hierarchy is restored to the destination site. The remaining subsites are restored in the same hierarchical order as seen in the source.
You cannot browse and restore the deleted items.
You cannot select multiple sites for a single restore operation.
