摘要： In a data recording apparatus, a monitoring unit detects a VLU including an MRB that manages an area that has not been accessed for a specified time period based on a current time, a time management table, and a parameter table. From MRBs of the detected VLU, the monitoring unit selects a plurality of MRBs with an unaccessed time period equal to or more than the specified time period and equal to or less than a total time. The monitoring unit performs synchronization process for data in a primary storage managed by the selected MRBs at a time. During the synchronization process, a correction value is adjusted when there is a data conflict with another device.

摘要： A data recording apparatus includes a determining unit that determines whether a storable area is present in the first storage device. The storable area is a combination of a plurality of empty areas having contiguous physical addresses with a total data volume larger than that of a volume of the data. When the determining unit determines that the storable area is present, a first storage unit stores the data in the storable area, and a second storage unit stores the data that has been stored by the first storage unit in the storable area as a lump into the second storage device.

摘要： At power-on again, a restore processing unit restores block information tables from a primary storage to a volatile memory. After classifying the block information tables into group-specific links of a plurality of time zones, a first sort processing unit connects the group-specific links to form a group classification link. Then, a second sort processing unit sequentially retrieves the block information tables of the group classification link from the earliest time stamp side for insertion in a position so as to achieve a time-stamp ascending order, thereby reconfiguring the links.

摘要： A RAID apparatus that at least duplicates identical data to store thus duplicated data, which, when an instruction of writing data is given, writes data to a local cache and to a mirror cache, and writes data of the local cache to a primary disk and writes data of the mirror cache to a secondary disk. When an instruction of reading out data is given, and specified data is retained in the caches, the RAID apparatus outputs valid data of the local cache or the mirror cache, while when specified data is not retained in the caches, the RAID apparatus outputs valid data of the primary disk or the secondary disk.
