Data management system and data management method
A data management system for backing up data in a first environment to a second environment includes: backup management information in which source data, backup data, a backup method, and data backed up using the backup method are associated; and a secondary usage data copy unit serving as a secondary usage processing unit that receives a usage request for the backup data stored in the second environment, wherein the secondary usage processing unit refers to the backup management information, specifies the backup data required for processing the usage request, specifies the backup method for the backup data, restores the backup data on the basis of the specified backup method, and enables processing of the usage request.
1. A data management system for backing up data of a first environment to a second environment, the data management system comprising:
a memory; and
one or more processors that are communicatively coupled to the memory, wherein the one or more processors are collectively configured to:
obtain backup management information in which source data, backup data, and a backup method are associated,
receive a usage request for the backup data stored in the second environment,
present a catalog indicating target candidates for the usage request, and
refer to the backup management information, specify backup data required for processing the usage request, specify a backup method for the backup data, restore the backup data on the basis of the specified backup method, and enable processing of the usage request.
2. The data management system according to claim 1 , wherein
the first environment is an on-premises environment,
the second environment is a cloud environment, and
the first environment stores the data in block storage.
3. The data management system according to claim 1 , wherein the one or more processors are further configured to:
receive a user selection from among the target candidates, and in a case where backup data of the selected data exists in the second environment, restore the backup data in the second environment and process the usage request.
4. The data management system according to claim 1 , wherein the one or more processors are further configured to:
receive a user selection from among the target candidates, and in a case where backup data of the selected data does not exist in the second environment, perform remote access processing on the data of the first environment.
5. The data management system according to claim 4 , wherein the one or more processors are further configured to:
construct a remote access environment by generating a snapshot of data in the first environment and map the generated snapshot to a volume in the second environment.
6. A data management method, in which a data management system for backing up data of a first environment to a second environment performs the steps comprising:
generating backup management information by associating source data, backup data, and a backup method;
receiving a usage request for the backup data stored in the second environment;
presenting a catalog indicating target candidates for the usage request; and
specifying backup data required for processing the usage request by referring to the backup management information, specifying a backup method for the backup data, restoring the backup data on the basis of the specified backup method, and enabling processing of the usage request.
