Abstract: Methods, systems, and configured storage media are provided for flexible data mirroring. In particular, the invention provides many-to-one data mirroring, including mirroring from local servers running the same or different operating systems and/or file systems at two or more geographically dispersed locations. The invention also provides one-to-many data mirroring, mirroring with or without a dedicated private telecommunications link, and mirroring with or without a dedicated server or another server at the destination(s) to assist the remote mirroring unit(s). In addition, the invention provides flexibility by permitting the use of various combinations of one or more external storage units and/or RAID units to hold mirrored data. Spoofing, SCSI and other bus emulations, and further tools and techniques are used in various embodiments of the invention.

Abstract: In one of the storage control apparatuses in the remote copy system which performs asynchronous remote copy between the storage control apparatuses, virtual logical volumes complying with Thin Provisioning are adopted as journal volumes to which journals are written. The controller in the one of the storage control apparatuses assigns a smaller actual area based on the storage apparatus than in case of assignment to the entire area of the journal volume, and adds a journal to the assigned actual area. If a new journal cannot be added, the controller performs wraparound, that is, overwrites the oldest journal in the assigned actual area by the new journal.

Abstract translation: 在存储控制装置之间执行异步远程复制的远程复制系统中的一个存储控制装置中，采用符合精简配置的虚拟逻辑卷作为写入日志的期刊卷。 存储控制装置之一中的控制器基于存储装置分配比在日志卷的整个区域分配的情况更小的实际区域，并将日志添加到所分配的实际区域。 如果不能添加新的日志，则控制器执行环绕，也就是覆盖新日志在指定的实际区域中的最旧日志。

Abstract: A computer system for performing a remote copy using a journal so as to maintain conformability of data stored in a secondary storage system even though a time stamp is not granted to write data received by a primary storage system. A storage managing unit issues an ID, such as a time stamp number (TS#) next to an immediately previously issued ID to one or more primary storage systems (PDKCs) at regular or irregular intervals. Upon receiving a write command, each PDKC prepares a journal (JNL) including a replica of write data and the newest ID from the storage managing unit, and transmits the journal to a secondary storage system (SDKC). The SDKC stores a received JNL and reflects up to a particular JNL of non-reflected JNLs in a secondary volume. The particular JNL has an ID older by one than the oldest ID of the newest arrival completion IDs in one or more SDKCs.

Abstract translation: 一种用于使用日志执行远程复制以便保持存储在辅助存储系统中的数据的一致性的计算机系统，即使时间戳未被授予以写入由主存储系统接收的数据。 存储管理单元以规则或不规则的间隔向一个或多个主存储系统（PDKC）发出紧邻先前发行的ID的ID，诸如时间戳号（TS＃）。 在接收到写命令时，每个PDKC从存储管理单元准备包括写数据副本和最新ID的日志（JNL），并将日志发送到辅助存储系统（SDKC）。 SDKC存储接收的JNL，并反映到辅助卷中的特定JNL未反映的JNL。 特定的JNL具有比一个或多个SDKC中的最新到达完成ID的最早ID更旧的ID。

Abstract: High availability and disaster recovery can be achieved within a database management system by detecting which parts of a file have changed and sending the changed parts to secondary servers, without sending the entire file that has experienced the changes. A log cracker reads data from a transaction log that stores records from a database and a separately maintained file system. The log cracker sends mirror commands with some of the transaction log data to the file system to initiate mirroring of the data from the file system to secondary servers. The log data is then subsequently sent to the secondary servers as well, to enable identification of changed data without having to transfer the entire file that has been changed.

Abstract translation: 通过检测文件的哪些部分已更改并将更改的部分发送到辅助服务器，可以在数据库管理系统中实现高可用性和灾难恢复，而不会发送经历更改的整个文件。 日志破解器从事务日志中读取数据，该数据从数据库和单独维护的文件系统中存储记录。 日志破解器将镜像命令与一些事务日志数据发送到文件系统，以便将数据从文件系统镜像到辅助服务器。 然后将日志数据发送到辅助服务器，以便能够识别已更改的数据，而无需传输已更改的整个文件。
