Is there a way to restore a single document library and/or site from a full backup? I need to restore a single file actually, but find that our vendor had set us up with only a full backup and an incremental backup strategy that backs up the entire farm.
The only way i think you can restore your single file is to restore the full backup on some test server. The best practice to be followed while handling document is not taken care in your case hence that seems to be only solution
