    • A method includes identifying a first boot configuration type for a disk image. The disk image includes a master boot record and a disk partition. The disk partition comprises a volume boot record. The master boot record comprises first instructions for loading an operating system, and the volume boot record comprises second instructions for loading the operating system. The method further includes receiving an input indicative of a second boot configuration type. The method also includes modifying the disk image to use the second boot configuration type to load the operating system by modifying the first instructions and the second instructions.
    • 一种方法包括识别磁盘映像的第一引导配置类型。 磁盘映像包括主引导记录和磁盘分区。 磁盘分区包括卷引导记录。 主引导记录包括用于加载操作系统的第一指令,并且卷引导记录包括用于加载操作系统的第二指令。 该方法还包括接收指示第二引导配置类型的输入。 该方法还包括修改磁盘映像以使用第二引导配置类型来通过修改第一指令和第二指令来加载操作系统。

    • Systems and methods for generating a bookmark for a snapshot of one or more volumes of a production server include initiating a snapshot process to capture a shadow copy of a snapshot-volume set, which includes one or more volumes of the production server. The snapshot process (e.g., Volume Shadow Copy Service of Windows™ operating system) may include (a) temporarily freezing operations on a file system of the production server, and (b) releasing a freeze of operations on the file system of the production server. A bookmark for the shadow copy (representing a consistent state of the associated volumes) may be generated such that the bookmark corresponds to a completion of the temporarily freezing or releasing a freeze of the operations. The bookmark may include a point in time of the completion of the temporarily freezing or releasing the freeze of the operations.
    • 用于生成一个或多个卷的生产服务器的快照的书签的系统和方法包括启动快照过程以捕获快照卷集的卷影副本,其包括生产服务器的一个或多个卷。 快照过程(例如,Windows TM操作系统的卷影复制服务)可以包括(a)临时冻结在生产服务器的文件系统上的操作,以及(b)释放对生产服务器的文件系统的操作冻结 。 可以生成卷影副本的书签(表示相关联的卷的一致状态),使得书签对应于完成暂时冻结或释放操作的冻结。 书签可以包括暂时冻结或释放操作冻结的时间点。

    • Systems and methods for replicating data from a production server to a backup server include recording at least one operation on one or more data items stored in a volume of a production server. The operation may be recorded as at least one journal event in a memory. A determination may then be made regarding whether a system malfunction incident has occurred in the production server and if so, a first set of journal events may be transferred from the memory to an auxiliary storage at a first time instant. At a second time instant, a second set of journal events recorded in the memory between the first and second time instants may be transferred to the auxiliary storage. At one journal event stored in the auxiliary storage unit may then be sent for replication to a backup server.
    • 用于将数据从生产服务器复制到备份服务器的系统和方法包括在存储在生产服务器的卷中的一个或多个数据项上记录至少一个操作。 该操作可以被记录在存储器中的至少一个日志事件。 然后可以确定在生产服务器中是否发生了系统故障事件,如果是,则可以在第一时刻将第一组日志事件从存储器传送到辅助存储器。 在第二时刻,记录在第一和第二时刻之间的存储器中的第二组日志事件可以被传送到辅助存储器。 然后可以将存储在辅助存储单元中的一个日志事件发送到备份服务器进行复制。

    • Systems and methods for replicating data from a production server to a backup server include identifying one or more data blocks of a file that were modified after a first time instant and before a second time instant. The file may be associated with a protected directory of the production server. An representative data block (e.g., including a hash value) for at least one of the identified data blocks may be computed using a cryptography algorithm, e.g., MD5 or SHA-1. The computed cryptographic data block representing the identified data block may then be sent for replication to the backup server. An operation performed between the first time instant and the second time instant on one or more files of the protected directory may be recorded, and sent to the backup server.
