    Abstract: Data can be protected at a production server in a virtually continuous fashion, without necessarily imposing severe constraints on the source application(s). For example, a production server can create an application-consistent backup of one or more volumes, the backups corresponding to a first instance in time. A volume filter driver can monitor data changes using an in-memory bitmap, while a log file and/or update sequence number journal can keep track of which files have been modified. The volume updates are also consistent for an instance (later) in time. At the next replication cycle, such as every few minutes (however configured), the volume filter driver passes each in-memory bitmap to the physical disk on the production server. The production server then sends the updates to the backup server, which thus stores application-consistent backups for the volume for multiple instances of time.

    Abstract translation: 可以在生产服务器上以几乎连续的方式保护数据，而不必对源应用程序施加严格的约束。 例如，生产服务器可以创建一个或多个卷的应用程序一致性备份，备份与时间对应的第一个实例。 卷过滤器驱动程序可以使用内存中位图来监视数据更改，而日志文件和/或更新序列号日志可以跟踪哪些文件已被修改。 对于一个实例（稍后）的时间，卷更新也是一致的。 在下一个复制周期（例如每隔几分钟配置一次），卷过滤器驱动程序将每个内存中的位图传递到生产服务器上的物理磁盘。 然后，生产服务器将更新发送到备份服务器，从而存储多个时间实例的卷的应用程序一致性备份。

    Abstract: Embodiments are directed to efficiently backing up portions of data and to performing a scoped data recovery. In an embodiment, a computer system preloads data images with data corresponding to various different software applications or operating systems. The computer system chunks the data images, so that each data image is divided into multiple data chunks, and where each data chunk is represented by a hash value. The computer system then receives, from a user, portions of delta data representing data differences between the received user data and the data in the preloaded data images. The computer system also generates a logical backup representation that includes the data chunk hash values for the preloaded data images as well as the delta data received from the user. This logical representation allows restoration of the user's data using only the hash values and the delta data.

    Abstract: A computer program product for implementing a method for performing a scoped data recovery, the computer program product comprising one or more computer-readable storage media having stored thereon computer-executable instructions that, when executed by one or more processors of the computing system, cause the computing system to perform the method, the method comprising: an act of defining a disaster recovery policy that specifies which software applications among a plurality of different software applications is to be restored after a disastrous event has occurred; an act of receiving, from a generated virtual hard disk, difference data comprising data differences between data received from a user and one or more preloaded data images, the virtual hard disk being configured to receive the difference data from the user; an act of determining, based on the disaster recovery policy, which software application's data is to be restored; and an act of restoring the software application delta data to the user according to the policy.

    Abstract: Implementations of the present invention provide systems, methods, and components configured to preserve valid shadow copies during replication cycles, before those valid shadow copies have expired. In particular, one or more components can identify the size and rate of changes in production server data that will be applied to a new volume shadow copy. The components can then determine the storage area that would be needed to store the new volume shadow copy in the backup volume and apply changes onto the backup volume if there is appropriate space. If there is not an appropriate amount of space, the components can alert the system that new action should be taken to preserve both prior, valid shadow copies as well as new shadow copies. For example, a backup administrator may need to increase the shadow copy storage space, or assign a new storage medium for handling new shadow copies.
