Backup system and method based on data characteristics
First Claim
1. A backup system, comprising:
- a backup source computer device that stores backup target data;
a plurality of backup destination computer devices each connected to the backup source computer device via a network;
a backup mode selector that select, according to data characteristics of the backup target data, any one backup mode from among a plurality of pre-prepared backup modes; and
a backup executor that stores the backup target data by transferring same from the backup source computer device to a backup destination computer device that is selected on the basis of the selected backup mode from among the backup destination computer devices.

Abstract
The present invention permits backup processing suited to data characteristics relating to backup target data by means of a method that is simple for the user. Data characteristic classification definition information, in which data characteristic IDs correspond with one or more data characteristic types respectively, and mapping information, in which backup destination server information corresponds with one or more data characteristic IDs respectively, are prepared. The backup source server 3 sets data characteristic IDs in each of the backup target files on the basis of metadata of designated backup target files and of the data characteristic classification definition information, and then determines backup destination servers 6A to 6C for each of the backup target files on the basis of the set data characteristic IDs and mapping information and transmits the backup target files to the determined servers 6A to 6C.

11. A backup method that performs a backup between a backup source computer device for storing backup target data and a plurality of backup destination computer devices each connected to the backup source computer device via a network, the backup method comprising the steps of:
-
determining data characteristics pertaining to backup target data on the basis of characteristic classification conditions for classifying data characteristics;
determining a backup destination computer device for each of the backup target data on the basis of the determined data characteristics and of backup destination mapping information that is constituted so that at least one or more of the backup destination computer devices constituting backup destinations correspond(s) with each of the data characteristics;
collecting, for each of the backup destination computer devices, the backup target data corresponding with the backup destination computer devices;
generating, for each of the backup destination computer devices, a backup list that includes information specifying backup target data to be acquired by the backup destination computer devices;
transmitting the generated backup lists to the backup destination computer devices; and
transferring the backup target data from the backup source computer device to the backup destination computer devices on the basis of the basis of the received backup lists.

12. A computer device, comprising:
-
a component that stores characteristic classification conditions for classifying data characteristics;
a component that determines data characteristics pertaining to backup target data on the basis of the characteristic classification conditions;
a component that stores backup destination mapping information constituted such that at least one or more backup destination computer devices constituting a backup destination correspond(s) with each of the data characteristics;
a component that determines a backup destination computer device for each of the backup target data on the basis of the determined data characteristics and the backup destination mapping information;
a component that collects, for each of the backup destination computer devices, the backup target data corresponding with the backup destination computer devices and generating, for each of the backup destination computer devices, a backup list including information specifying backup target data to be acquired by the backup destination computer devices;
a component that transmits the generated backup lists to the backup destination computer devices; and
a component that transfers the backup target data to the backup destination computer devices when the backup destination computer devices request the acquisition of backup target data on the basis of the transmitted backup lists.
