Abstract:
One or more techniques and/or computing devices are provided for non-disruptively establishing a synchronous replication relationship between a primary volume and a secondary volume and/or for resynchronizing the primary volume and the secondary volume. For example, a baseline snapshot and one or more incremental snapshots of the primary volume are used to construct and incrementally update the secondary volume with data from the primary volume. A dirty region log is used to track modifications to the primary volume. A splitter object is used to split client write requests to the primary volume and to the secondary volume. A synchronous transfer engine session is initiated to processing incoming client write requests using the dirty region log. A cutover scanner is used to transfer dirty data from the primary volume to the secondary volume. In this way, a synchronous replication relationship is established between the primary volume and the secondary volume.

Claim (Index 1):
A method comprising:\n performing a baseline transfer of data from a primary volume to a secondary volume using a baseline snapshot of the primary volume; performing incremental transfers of data from the primary volume to the secondary volume using incremental snapshots until a criteria is met; splitting write requests to target the primary volume and the secondary volume based upon the criteria being met; tracking modifications by write requests to the primary volume using a dirty region log with indicators indicating whether regions have been modified; performing an asynchronous transfer of data from the primary volume to the secondary volume based upon the dirty region log being used to track dirty regions modified by write requests; committing incoming write requests, corresponding to the dirty regions, to the primary volume; committing incoming write requests, corresponding to non-dirty regions, to the primary volume and the secondary volume; and scanning the dirty region log to identify and transfer data of the dirty regions from the primary volume to the secondary volume to place the primary volume and secondary volume into a synchronous replication state.
