摘要： In a storage device, a method is provided for preventing the risk of data loss and a significant decrease of writing speed due to area shrinkage when erased erase blocks have become fewer. A process of allocating a new page includes determining whether the length of a deallocated pages list is longer than n pages. If the list length is longer, one page is allocated from the deallocated pages list. If the list length is shorter, a capacity shortage error returns. Deleting a file using an erased pages list includes determining whether a page to be processed is emptied by deleting the file. If not so, the file is deleted from the page. If so, the contents of the last page-a in occupied pages are copied to the page, the page-a is written with data for erasure, and any erase block included in the page-a is made erasable.

摘要： A technology for verifying backup data capable of synchronizing timings of checksum calculation and verifying data consistency regardless of the storing position of the data is provided. In a backup system using a data update log, a checksum of data of a backup source and a checksum of backup data are checked, thereby verifying data consistency. Data check log generation means and the like are provided so that the data update log and the data check log are transmitted in order to a secondary site. By this means, the timings of the checksum calculation are synchronized. Further, by providing data area extraction means and the like, the verification of data consistency can be performed regardless of the storing position of the data.

摘要： A method for duplicating transactions in a disaster recover system is disclosed. In this method, transactions and queries input to a primary database system are copied to a secondary database system and both database systems execute the queries and save the results permanently to each database, thereby maintaining duplicated data. When executing a query on the primary database system, if the query is a commit, the primary system simultaneously copies uncopied queries placed in a queue to the secondary database system and then executes the query. By using this processing procedure, the invention realizes a disaster recovery system which carries out copying transactions from one site to another site without losing the transactions, while reducing the influence of copy operation on the transaction processing performance.
摘要翻译：公开了一种在灾难恢复系统中复制事务的方法。在这种方法中，将输入到主数据库系统的事务和查询复制到辅助数据库系统，并且两个数据库系统都执行查询并将结果永久保存到每个数据库，从而保留重复的数据。当在主数据库系统上执行查询时，如果查询是提交，则主系统会同时将放入队列中的未查找的查询复制到辅助数据库系统，然后执行查询。通过使用该处理过程，本发明实现了在不丢失事务的情况下执行从一个站点到另一站点的复制事务的灾难恢复系统，同时减少了复制操作对事务处理性能的影响。

摘要： Provided is a backup method including a step (S1) of reading a log which is a data update difference, and identifying a data storage area (page) of backup data, a step (S2) of determining high/low reusability of the identified data storage area, a step (S3) of storing a log corresponding to a data storage area determined to be low in reusability in a log storage area preset on a memory, and a step (S4) of applying a log corresponding to a data storage area determined to be high in reusability to the identified data storage area in a cache area set on the memory, and updating the data storage area. Thus, by further reducing the number of I/O times in an external storage system of a standby system which backs up data by log transfer, it is possible to reduce introduction costs of a backup system and its normal-time operation's costs at normal times.

摘要： A high availability database system, subject to a failure causing data corruption in the active server system, may recover valid data prior to the corruption, and use the protected and recovered data to effect a failover. At the time when a stand-by computer system detects occurrence of a failure, a pair split is done to the data area to protect the data area data of time T0, just before the occurrence of the failure, and another pair split is done to the log area at the time, where the log area is corrupted or a time T3, where the failover is to take effect without corrupting data, to protect the log area containing data at a given time between time T0 and time T3. By using the data and log areas thus protected, the stand-by computer system may take over valid data and log areas to perform a failover.
摘要翻译：高可用性数据库系统受到在活动服务器系统中导致数据损坏的故障的影响，可能会在损坏之前恢复有效数据，并使用受保护和恢复的数据实现故障切换。当备用计算机系统检测到故障发生时，对数据区域进行对分割，以在发生故障之前保护时间T 0的数据区域数据，并且另一对分裂完成到日志区域被破坏的日志区域或时间T 3，其中故障转移将在不破坏数据的情况下生效，以在时间T 0和时间T 3之间的给定时间保护包含数据的日志区域。通过使用受保护的数据和日志区域，备用计算机系统可以接管有效的数据和日志区域以执行故障转移。
