Method, apparatus, and computer readable medium for managing replication of back-up object

Abstract

Replication data acquired by a copy and a volume storing therein this replication data are flexibly managed in response to the needs of a user depending on the attributes of a file which becomes the target of the copy executed by a storage apparatus. More concretely, when receiving an instruction of the backup for a file to be the backup target, if there has been received a specification about the attributes of the backup target, or a method of managing replication data acquired by the backup of this backup target, the specified attributes and the like are managed in a manner of being made to correspond to the replication data and a volume name into which this replication data should be stored.

       14 . A computer connected to a storage apparatus for executing a backup by copying data from each original volume into each of a plurality of duplicate volumes corresponding thereto upon receiving pair information, each of said duplicate volumes storing backup data copied at a respective timing, said pair information including each original-volume name and each duplicate-volume name corresponding thereto, 
 said computer comprising:    a memory unit for holding a first table and a second table, wherein files becoming backup targets are classified into plural groups each corresponding to a respective user business, said first table being designed for storing file names in a manner of being made to correspond to each group name, said file names being included in said each group, said second table being designed for storing said file names and said group in a manner of being made to correspond to said duplicate-volume names;    a volume setting unit for executing a step of:    when transmitting said pair information to said storage apparatus in response to a receipt of a specified first group name, said pair information including a first original-volume name and a first duplicate-volume name corresponding thereto, said first original-volume for storing therein a first file, storing said first file name and said first group name whose specification has been received into said second table in a manner of being made to correspond to said first duplicate-volume name; and    a display unit for displaying a plurality of sets each of a group name, said original-volume name and at least one of states of each of said duplicate-volume names, each of said duplicate volumes storing backup data copied at a respective timing, said state including a first indication for showing that said duplicate-volume has been selected and a second indication showing that said duplicate-volume can be used.    
   
   
       15 . A replication-data management method whereby, using a computer connected to a storage apparatus for executing a backup by copying data from each original volume into each of a plurality of duplicate volumes corresponding thereto upon receiving pair information, each of said duplicate volumes storing backup data copied at a respective timing, said pair information including each original-volume name and each duplicate-volume name corresponding thereto, said computer executing steps of: 
 storing a first table and a second table, wherein files becoming backup targets are classified into plural groups each corresponding to a respective user business, said first table being designed for storing file names in a manner of being made to correspond to each group name, said file names being included in said each group, said second table being designed for storing said file names and said group in a manner of being made to correspond to said duplicate-volume names;    when transmitting said pair information to said storage apparatus in response to a receipt of a specified first group name, said pair information including a first original-volume name and a first duplicate-volume name corresponding thereto, said first original-volume for storing therein a first file, storing said first file name and said first group name whose specification has been received into said second table in manner of being made to correspond to said first duplicate-volume name; and    displaying a plurality of sets each of a group name, said original-volume name and at least one of states of each of said duplicate-volume names, each of said duplicate volumes storing backup data copied at a respective timing, said state including a first indication for showing that said duplicate-volume has been selected and a second indication for showing that said duplicate-volume can be used.
