Method, device, and computer program product for managing snapshot in application environment

A device for managing snapshots in an application environment, the application environment comprising a first application system and a second application system, the device comprising:

• at least one processor;
• a volatile memory;
• and
• a memory coupled to the at least one processor and having instructions stored thereon, the instructions, when executed by the at least one processor, causing the device to perform acts comprising:
• identifying a group of snapshots of the first application system while the first application system is in a fracture state in which synchronous communication between the first application system and the second application system is paused;
• obtaining a group of snapshot differences between two successive snapshots in the group of snapshots, the group of snapshots being arranged in chronological order according to when the snapshots were generated;
• and
• transmitting the group of snapshot differences from the first application system to the second application system in response to determining the synchronous communication between the first application system and the second application system is resumed.

A computer program product having a non-transitory computer readable medium which stores a set of instructions to manage snapshots in an application environment, the application environment comprising a first application system and a second application system;

• the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:
• identifying a group of snapshots of the first application system while the first application system is in a fracture state in which synchronous communication between the first application system and the second application system is paused;
• obtaining a group of snapshot differences between two successive snapshots in the group of snapshots, the group of snapshots being arranged in chronological order according to when the snapshots were generated;
• and
• transmitting the group of snapshot differences from the first application system to the second application system in response to determining the synchronous communication between the first application system and the second application system is resumed.
