摘要： There is a journal area and one or more logical volumes comprising a first logical volume. The journal area is a storage area in which is stored a journal data element, which is a data element that is stored in any storage area of a plurality of storage areas configuring a logical volume, or a data element that is written to the storage area. A controller has a size receiver that receives a write unit size, which is the size of a write data element received from a computer, and a size setting unit that sets the received write unit size in a memory for one or more logical volumes. The size of a journal data element stored in a journal area based on the set write unit size is the write unit size.

摘要： A first storage system comprises a first logical volume, and a first controller that has a first memory. A second storage system comprises a second physical storage device that constitutes the basis of a second logical volume and a journal area, and a second controller that has a second memory. At least the first memory stores a write unit size, which is the size of a write data element. The journal area is a storage area in which is stored a journal data element, which is a data element that is stored in any block of a plurality of blocks configuring the first and/or second logical volume, or a data element that is written to this block. The size of the journal data element, and the size of the respective blocks that are managed as the respective components of the first and second logical volumes are the write unit size.

摘要： A storage system, upon receiving a marker from a host computer, executes a generation determination process for determining a generation of a first logical volume that is used by a host computer, and writes information related to the generation determined in this generation determination process to a physical storage device and/or a memory. A backup controller determines whether or not any data or a specified file and/or folder inside the first logical volume of the immediately preceding generation has changed, and when the result of this determination is affirmative, sends a marker insert indication, which induces the issuance of a marker, to the host computer, and when the result of the determination is negative, does not send the marker insert indication to the host computer.

摘要： An intermediate value derived from old and new data record values or old and new data themselves are sent from a control unit to a disk unit which stores a parity record as information necessary for updating parity. The disk unit reads an old parity record and generates a new value of parity record based on the read old parity and the information received from the control unit. The generated new value is stored in an empty record on the storage medium to which a read/write head is first positioned after the generation of the new value and in which effective data has not been stored. In a disk array system, a time required to update the parity record due to the updating of the data record is reduced and a performance of the storage unit subsystem is improved.

摘要： A storage device system comprises interfaces connected to computers, a plurality of magnetic disks, and a control device that controls the plurality of magnetic disks. When a command from one of the computers instructing a tape library device to load a magnetic tape into a tape device is received by one of the interfaces, the control device selects a storage region that is managed as a virtual tape from among storage regions of the magnetic disks. When one of the interfaces receives an access request from the computer to the tape device, the control device controls to access the storage region selected.
