Abstract: In a DR system, from the viewpoint of device cost, when search is not carried out, a physical application where log recovery is available by inexpensive DB appliance server is adopted. Further, a local mirror operation at a secondary site is not carried out. Furthermore, from the viewpoint of operation, by a log apply function unit, the tendencies of a log application and operations are monitored, and a search process is accepted according to the progress conditions of the log application. When the log application does not catch up sufficiently, the search is not accepted. Moreover, when a consistency guarantee of a secondary DB is made, not transactions in process at the moment of search instruction are undone (rolled back), but only transactions in process at the moment of a search instruction are redone (rolled forward).

Abstract: When a public line is used for a remote copy function of storage in a disaster recovery (DR) system, the online performance is degraded due to the increase and decrease of the line utilization rate. Therefore, it is desired to change the remote copy function depending on the line utilization rate. Also, there is the possibility of data loss if disaster occurs during the copy between storage devices. Therefore, it is desired to perform the processing to detect the data status immediately before the occurrence of the disaster. By switching the synchronous transmission and the asynchronous transmission in accordance with the increase and decrease of the response time of the remote copy function between storage devices, the online performance of the primary site can be maintained without being influenced by the line utilization rate, and the data loss can be detected based on the used remote copy function.

Abstract: Database synchronization processing is completed within a reasonable time, using narrow-band network that connects a primary site to a secondary site, to reduce the running cost of a system. A primary DBMS has a transaction executing unit for reading a primary DB of a primary storage system to update data as requested in an update request, and a write unit for writing the updated data in the primary storage system. The primary storage system includes an unnecessary information removing unit for overwriting an unused area in the written data successively with one of a preset character and a preset value. The primary storage system is connected, via a network, to a second storage system which stores a copy of the primary DB. The primary storage system is connected to the network via a network device which has a data compression unit for compressing a succession of the same value.

Abstract: Provided is a technique of setting up a disaster recovery system. In a log-based disaster recovery system including a first site for processing data and a second site for storing a backup of the first site, the first site has a volume where data is stored and a volume that is made quiescent. The disaster recovery system accepts data updates while sequentially copying initial data from the quiescent volume to the second site. A copy of a log of the first site is kept in the second site and is synchronized with the original log. When data of the first site is updated and corresponding initial data has not been copied to the second site, the data to be updated is preferentially copied to the second site. A log is applied to the copied data, thereby matching data of the second site with data of the first site.

Abstract: A silicone-modified fluoropolymer is formed by first dissolving a fluoropolymer in an organic solvent, the fluoropolymer having at least one monomer of vinylidene fluoride coupled to a hexafluoropropylene monomer unit, and subsequently reacting the mixture with an amino silane coupling agent to form an aminosilane-modified fluoropolymer. The aminosilane fluoropolymer is subsequently heated and partially condensed with an oligomer of a silane compound including alkoxy silane. The resultant composition is suitable for use as a low refractive index layer in an antireflection coating on an optical substrate.

In a log-based disaster recovery system including a first site for processing data and a second site for storing a backup of the first site, the first site has a volume where data is stored and a volume that is made quiescent. The disaster recovery system accepts data updates while sequentially copying initial data from the quiescent volume to the second site. A copy of a log of the first site is kept in the second site and is synchronized with the original log. When data of the first site is updated and corresponding initial data has not been copied to the second site, the data to be updated is preferentially copied to the second site. A log is applied to the copied data, thereby matching data of the second site with data of the first site.

A primary DBMS (101) has a transaction executing unit (104) for reading a primary DB (119) of a primary storage system (110) to update data as requested in an update request, and a write unit (106) for writing the updated data in the primary storage system (110). The primary storage system (110) includes an unnecessary information removing unit (1400) for overwriting an unused area in the written data successively with one of a preset character and a preset value. The primary storage system (110) is connected, via a network (320), to a second storage system (120) which stores a copy of the primary DB (119). The primary storage system (110) is connected to the network (320) via a network device (140) which has a data compression unit for compressing a succession of the same value.
