摘要： 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.

摘要： 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.
摘要翻译：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。

摘要： 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.

摘要： Systems and methods for replicating data from a master server to a replica or backup server include capturing a read event associated with a retrieved file at the master server. The retrieved file may be generated by updating a reference file with remotely stored data. Attributes associated with the retrieved file may be checked to determine if they include attributes associated with the reference file, and if they do not, at least a portion of data and one or more attributes of the retrieved file may be copied or replicated to the replica server. The captured read event may be generated when an application attempts to access or read the retrieved file. An event associated with generation of the reference file may also be captured at the master server, and copies to the replica server.
