On Btrfs, there's no overwrite of metadata. The super keeps a record of current plus three backup sets of trees. You want to stop this file system quickly though, they don't stick around very long. Those root tree address can be plugged into 'btrfs restore' (offline scrape tool) to search for and extract the files you want.
