Snapshot creation with synchronous replication

A non-transitory machine readable medium having stored thereon machine executable code which when executed by a machine, causes the machine to:

• receive a request to create a snapshot of a first object, hosted by a first device, having a synchronous replication relationship with a second object hosted by a second device, wherein write operations are replicated to target both the first object and the second object before being acknowledged as complete based upon the synchronous replication relationship being in-sync;
• send a first snapshot request to the first device to create a first snapshot of the first object and a second snapshot request to the second device to create a second snapshot of the second object;
• resume replicating new incoming write operations and maintaining the synchronous replication relationship in-sync based upon the first snapshot and the second snapshot successfully completing before a timer times out;
• in response to receiving, from a client, a first delete snapshot command specifying that the first snapshot is to be deleted, generate a second delete snapshot command specifying that the second snapshot is to be deleted;
• synchronously implement the first delete snapshot command to delete the first snapshot at the first device and the second delete snapshot command to delete the second snapshot at the second device while maintaining the synchronous replication relationship in-sync where any uncompleted write operations, received before or during the synchronous implementation of the first delete snapshot command and the second delete snapshot command, are synchronously replicated to target both the first object and the second object before the uncompleted write operations are acknowledged as complete, wherein the uncompleted write operations are synchronously replicated in parallel during the synchronous replication of the first delete snapshot command and the second delete snapshot command;
• and
• transmit an acknowledgement to the client in response to both the first delete snapshot command and the second delete snapshot command successfully completing.

A computing device comprising:

• a memory comprising machine executable code;
• and
• a processor coupled to the memory, the processor configured to execute the machine executable code to cause the processor to:
• receive a request to create a snapshot of a first object, hosted by a first device, having a synchronous replication relationship with a second object hosted by a second device, wherein write operations are replicated to target both the first object and the second object before being acknowledged as complete based upon the synchronous replication relationship being in-sync;
• send a first snapshot request to the first device to create a first snapshot of the first object and a second snapshot request to the second device to create a second snapshot of the second object;
• resume replicating new incoming write operations and maintaining the synchronous replication relationship in-sync based upon the first snapshot and the second snapshot successfully completing before a timer times out;
• in response to receiving, from a client, a first delete snapshot command specifying that the first snapshot is to be deleted, generate a second delete snapshot command specifying that the second snapshot is to be deleted;
• synchronously implement the first delete snapshot command to delete the first snapshot at the first device and the second delete snapshot command to delete the second snapshot at the second device while maintaining the synchronous replication relationship in-sync where any uncompleted write operations, received before or during the synchronous implementation of the first delete snapshot command and the second delete snapshot command, are synchronously replicated to target both the first object and the second object before the uncompleted write operations are acknowledged as complete, wherein the uncompleted write operations are synchronously replicated in parallel during the synchronous replication of the first delete snapshot command and the second delete snapshot command;
• and
• transmit an acknowledgement to the client in response to both the first delete snapshot command and the second delete snapshot command successfully completing.
