Abstract
Prior to overwriting a block of data in a first volume of data on a primary host, the block of data is written to a first snapshot of the first volume. Subsequently, the first snapshot can be synchronized with a snapshot of a second volume of data on a secondary host, where the second volume is a replica of the first volume. To synchronize the snapshots, only a portion of the first snapshot (e.g., the block of data that was written to the first snapshot) is sent to the secondary host.
