Recovering a namespace held in a tree structure that has been corrupted includes scanning a linear representation of pages belonging to the tree structure to copy out keys from uncorrupted leaf pages into a new tree structure. The scan is repeated over snapshots that have been taken of the tree to find keys that are missing from the new tree structure. Upon finding a missing key in an uncorrupted leaf page of a snapshot, the missing key is copied out into the new tree structure unless the missing key has already been found and copied out from an uncorrupted leaf page of a more recent snapshot taken of the tree structure.
