    摘要: A remote file server managing a remote storage device and a local file server managing a local storage device are coupled to a communication network (e.g. the Internet). The local file server (A) replicates a file in the local storage device to the remote file server and, (B) if a first condition is satisfied, manages the replicated file which is the file from which the data is replicated as a migration target file. The local file server, even if the (B) is completed, does not delete the migration target file from the local storage device and, if the second condition is satisfied, deletes the migration target file from the local storage device.

    摘要: An object is to enable efficient shredding of recording media in association with migration. An information processing device (a server device 3) receives a data input/output request in a unit of a file transmitted from a client device 2, and performs writing and reading of data to and from a storage system 10 having a recording medium (hard disk drive 171) in which a file entity specified in the received data input/output request is stored in units of data blocks. The information processing device is communicatively coupled to a different storage device which is a migration destination of data. In the case where after the migration of certain data, different data is written in a data block of the certain data in an overlapped manner, the data block is not shredded if the data block is already shredded related to either of the overlapped certain and the different data after the migration.

    摘要: A server apparatus performs data I/O processing on a P-VOL in response to a request from a client apparatus and includes a file system which receives data write and read requests in units of files from the client apparatus. The server apparatus stores, into a D-VOL, differential data generated by updating the P-VOL, and manages a snapshot management table wherein a block address of the D-VOL storing the acquired differential data is registered. When a remaining capacity of a storage area of the D-VOL becomes equal to or less than a predetermined threshold value, the server apparatus enables a block of the D-VOL which had stored therein the differential data on a certain predetermined file, to be used as a storage area for newly acquired differential data.
