Claim:
1. A method for providing file system snapshots using selective tuple versioning in a computing environment using a processor device, comprising: receiving a request for updating at least one of a plurality of nodes and at least a node identification (ID) and associated attributes of the plurality of nodes, generating a new snapshot timestamp indicating the time of the updating, duplicating one of a plurality of rows of the plurality of nodes in the file system table into a new one of the rows of the plurality of nodes in the file system table with an end time set equal to a new snapshot timestamp if the snapshot has the snapshot timestamp that is greater than a start time of the plurality of nodes and less than the end time of the plurality of nodes, and updating the rows of the plurality of nodes in the file system table according to the update request, wherein the start time of the plurality of nodes is set equal to the new snapshot timestamp.
