Claim 4:
5. The system of claim 4, wherein each storage node of the plurality of storage nodes is further programmed to:
receive a read instruction referencing a read snapshot, the read instruction including a read address;
if the read address is found in the index of any segment mapped in the segment table to at least one of (a) the read snapshot and (b) any snapshot preceding the read snapshot, returning last-written data from at least one of (a) and (b) corresponding to the read address; and
if the read address is not found in the index of any segment mapped in the segment table to at least one of (a) the read snapshot and (b) any snapshot preceding the read snapshot, route the read instruction to a different storage node of the plurality of storage nodes that stores an ancestor snapshot of the read snapshot according to the hierarchical representation.
