Abstract
A processing device generates a clone of a first volume of storage, the first volume comprising a plurality of storage blocks, wherein the clone is a second volume that is writable and that references the plurality of storage blocks. The processing device increments a global volume count that represents a number of volumes. For each storage block of the plurality of storage blocks, the processing device postpones an update to metadata of the storage block until an event that causes any volume to stop referencing the storage block, wherein the metadata indicates volumes that reference the storage block.
