Abstract
Implementing point in time back-up. A method that may be practiced in a distributed computing environment. The distributed computing environment includes a number of computing system nodes. The method includes at a first node in the computing environment, taking a snapshot of a cluster volume. The cluster volume stores data items (e.g. files/blocks). Taking a snapshot includes marking a point in time for data items in the volume. The method further includes receiving a notification that a different node in the computing environment than the first node, has determined to change a data item in the cluster volume at a point after the marked point in time from an old version of the data item to a new version of the data item. The method further includes at the first node, saving the old version of the data item prior to modification.
