My organization's SharePoint site permissions were severely altered by our top level organization's SharePoint administrators. They have attempted to "restore" them by hand copying over permissions from a test server which failed miserably. We have asked them to do a restore of our site to the previous day's backup, however they say it isn't possible because our site is part of a site collection. I understand restoring a site collection will restore all the sites in the collection to the restore point, not only ours. However, I do know that it's possible to restore only our site out of the site collection even if it's restoring the entire site collection to a temp database and exporting only our site to "live" database. Can anyone give a guide on how to do this so I can provide it to the top level site administrators who say this isn't possible?
