A storage system performs transformations of data stored as source snapshots to obtain transformed snapshots. The storage system stores relations between source snapshots, for example, parent child relationships. The storage system analyzes relationships between source snapshots to determine relationships between transformed snapshots. The storage system creates a transformed snapshot based on a source snapshot. The storage system traverses the graph representing source snapshots to identify ancestor or descendants of the source snapshots that were previously transformed. The storage system determines the transformed snapshots corresponding to the ancestor and descendant source snapshots and relates them to the newly created transformed snapshot.
