Abstract
Disclosed is a method and a system for remote mirror data backup over a network. The system comprises a local domain site and at least one remote domain site, wherein each site has one domain mirror agent and one storage server system thereon. Each storage server system includes one or more storage servers, and one of the domain mirror agents is predefined as the master mirror agent. With such a remote mirror system, the method performs the operations of virtual mirror device allocation, mirror operation, data consistency check, third mirror allocation, and recovery of local storage device. The present invention expands the conventional logical volume management (LVM) to a network environment, effectively improving the backup/recovery capability of remote mirroring.
