Restore of deleted site
collection by power shell
This happens many times with the SharePoint
administrators that someone deletes the site unfortunately and want it back.
What happens if it’s also delete from the recycle bin.
We can still restore the deleted
site by using the power shell commands.
Initially get all the sites that
were deleted, this provides the sites deleted list with the Site ID
Get-spdeletedsite | select path,siteID
Once you get the details, Restore
the site with the below command.
Restore-spdeletedsite –identity siteID(which we got in last command)
