摘要： When an event occurs in a storage system that is not recognized by a host, it is not possible to recover data at the point before and after this event. Provided is a storage system including a first storage area storing data to be used by a computer, and a second storage area for storing updated data and its update log information when there is an update request from the computer to the first storage area. This storage system monitors its own storage system and detects an event, and creates a recovery point and its update log information based on the event. When the storage system receives a recovery command at a certain recovery point, it recovers data of the first storage area at the time of recovery point by writing, in a replication storage area at a certain point of the first storage area, update data up to the recovery point among the update data stored in the second storage area.

摘要： Provided are a computer system and its data control method that enable safe backup of data and reduction in the capacity of data to be backed up. A control processor refers to a differential and, if a differential bit is “0,” encrypts data of an online VOL with an encryption circuit by using key information, and transfers the encrypted data to a second storage system. If the differential bit is “1,” the control processor performs redundancy elimination processing to journal data, thereafter compresses the journal data with a compression circuit, encrypts the compressed journal data with an encryption circuit according to the key information, and transfers the journal data that was encrypted after compression to the second storage system.

摘要： The computer system includes a storage device, a virtual volume, a plurality of logical volumes each including a storage area and constituting a pool, and a controller for controlling the allocation of the storage area from the logical volumes in the pool to the virtual volume. The controller is configured to: manage, for each of the plurality of logical volumes in the pool, a capacity of the logical volume and a number of units of storage areas allocated to the virtual volume; allocate one or more units of storage area not allocated to virtual volume from the plurality of logical volumes in the pool to the virtual volume when it is necessary; detect a state where an imbalance occurs between the numbers of units of allocated storage areas of the logical volumes in the pool based on the managed information; and change the allocation in order to achieve a balance.
