Document Type and Number:
WIPO Patent Application WO/2010/145542
Kind Code:
A1
Abstract:
A data backup process method, data storage node device and data storage apparatus are provided. The method includes: numbering at least one data storage node in a data storage apparatus, wherein the data storage node includes a main storage area and a backup storage area, and logically connecting the main storage area in the data storage node with the backup storage area of the data storage node with a next adjacent number to enable the multiple data storage nodes to form an orderly and logically connected annular structure; respectively backing up the data stored in the main storage area of any one of the data storage nodes to the backup storage area of at least one data storage node whose number is next adjacent to the number of the data storage node in the annular structure. The method can provide the user with data redundancy among any number of disks, efficiently ensure the safety of the user data, and have strong flexibility and practicability.
