BACKUP OBJECT SENDING AND BACKUP METHOD, PRODUCTION END, DISASTER RECOVERY END, AND SYSTEM

摘要

The present invention is applicable to the technical field of distributed storage and provides a backup object sending and backup method, a production end, a disaster recovery end, and a system. In the sending method, a production end device sends a parent-child relationship table to a disaster recovery end device, the parent-child relationship table comprising a backup object number, a parent directory where a backup object is located, and a backup object name; and the production end device sends an operation request to the disaster recovery end device, the operation request comprising a backup object number and a backup object operation type, so that the disaster recovery end device generates an operation path of the backup object according to the parent-child relationship table, and performs, according to the operation path and the backup object operation type, a corresponding operation on the backup object. In the present invention, the step of the working path switching is removed, and backup operations are simplified, thereby improving the backup efficiency of the backup object.
