Method, apparatus, and computer readable medium for managing back-up
First Claim
1. 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 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.

Abstract
Duplicate data obtained by copying and a volume containing it are flexibly managed according to the attribute of the file to be copied by a storage apparatus as is required by a user. When receiving a backup instruction for the file to be backed up, an instruction for a method managing the attribute of the object to be backed up and the duplicate data obtained by the backup of the object to be backed up is also received. In this case, the duplicate data and the volume name to store it are related, thereby managing the specified attribute.

6. A storage medium containing a program for causing a computer holding a first table storing a backup method identifier for identifying a backup method defining a method for executing a backup of a volume and a volume name of the volume to be backed up in a correspondence manner, to execute:
-
a procedure of holding a second table storing the volume name and state information concerning the volume state in a correspondence manner, and a third table storing a condition concerning a volume state and a backup method identifier in a correspondence manner;
a step of judging whether state information stored in the second table in a correspondence manner to the first volume name has been updated;
a procedure of extracting the updated state information when the information is judged to have been updated, a procedure of extracting a first backup method identifier and a second backup method identifier from backup method identifiers stored in the third table;
a procedure of 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
a procedure of storing the second backup method identifier stored 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. - View Dependent Claims (7, 8, 9, 10)

11. A computer holding a first table for storing a backup method identifier for identifying a backup method defining a method for executing a backup of a volume and a volume name of the volume to be backed up in a correspondence manner, a second table for storing state information concerning the volume state and the volume name 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 computer having a rule creation unit for executing:
-
a step of extracting updated state information when the state information stored in the second table in a correspondence manner to a first volume name is updated;
a step of extracting a first backup method identifier and a second backup method identifier from backup method identifiers stored in the third table;
a step of storing the first backup method identifier in the first table in a correspondence manner to a 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
a step of 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. - View Dependent Claims (12, 13, 14, 15)
