Abstract
An ACL, a setting table, and backup data are used to create an inter-base data sharing file system at a base permitted to share data. This enables data to be shared by bases. In a process for restoring backup data, with reference to the ACL and the setting table, a data management computer system determines whether or not each restore destination base is permitted to share data, and executes a restore process only on restore destination bases permitted to share data.
Claims15
A method for managing an information processing system (100) comprising a plurality of sub-computer systems (1800,1810) and a data management computer system (1820) connected to the plurality of sub-computer systems (1800, 1810),
- the plurality of sub-computer systems (1800, 1810) comprising storage subsystems (1500, 1600), respectively, to provide data to client computers (1300, 1310, 1320, 1330, 1340, 1350),
- the data management computer system (1820) managing the data shifted from each of the sub-computer systems (1800, 1810),
- the method comprising:
- the data management computer system (1820) managing backup data (2450) for the first sub-computer system (1800), and based on data sharing permission/inhibition information (3030, 13010) indicative of data shared by the plurality of sub-computer systems (1800, 1810), restoring at least a part of the backup data (2450) for the first sub-computer system (1800) in a second sub-computer system (1810) different from the first sub-computer system (1800), and
- the second sub-computer system (1810) storing the data restored by the data management computer system (1820) in the storage subsystem (1600) in the second sub-computer system to generate a shared file system.
A data management computer system (1820) connected to a plurality of sub-computer systems (1800, 1810) to manage data shifted from the sub-computer systems (1800, 1810),
- the data management computer system (1820) comprising a control device (1200) and a storage system (1700) with a disk device,
- wherein the storage system (1700) stores backup data (2450) for a first sub-computer system (1800) included in the plurality of sub-computer systems (1800, 1810), and
- based on data sharing permission/inhibition information (3030, 13010) indicative of data shared by the plurality of sub-computer systems (1800, 1810), the control device (1200) restores at least a part of the backup data (2450) in a second sub-computer system (1810) different from the first sub-computer system (1800) to enable a shared file system to be generated in the second sub-computer system (1810).
