Patent ID: 7007144

Claim:
A backup method selection method using a computer holding a first table storing a backup method identifier for identifying a backup method defining a method for executing backup of a volume and a volume name of the volume to be backed up in a correspondence manner, wherein the computer holds a second table for storing the volume name and state information concerning a state of the volume in a correspondence manner, and a third table for storing a condition concerning the volume state and a backup method identifier in a correspondence manner, the selection method comprising steps of: judging whether state information stored in the second table in a correspondence manner to the first volume name has been updated; extracting the updated state information when the state information is judged to have been updated; extracting a first backup method identifier and a second backup method identifier from backup identifiers stored in the third table; storing the first backup method identifier in the first table in a correspondence manner to the first volume name when the extracted state information satisfies a first condition stored in the third table in a correspondence manner to the extracted first backup method identifier; and storing the second backup method identifier in the first table in a correspondence manner to the first volume name when the extracted state information satisfies a second condition stored in the third table in a correspondence manner to the extracted second backup method identifier.
