SYSTEM AND METHOD FOR REARRANGING ACTIVE APPLICATION TO COMPUTER POSITIONED IN TOPOLOGICALLY REMOTE LOCATION

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for rearranging an active application to a computer positioned in a topologically remote location.

SOLUTION: In rearrangement of the application, its application data are copied in a storage system of a computer system positioned in the topologically remote location outside a storage area network or a cluster of an original computer system. A stateful checkpoint of the application is generated to be copied in the computer system in the topologically remote position. For example, operation can be carried out by using a peer-to-peer remote copying action. The application data and checkpoint metadata can be copied in an instant copy or flash copy storage medium for generating copies of the checkpoint metadata about a recovery point of the application.
