摘要： 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.

摘要： Controlling data retention of a collection of data in a data store. An instruction is received to store a shadow collection of data to the data store. The data store has a previous version of the shadow collection of data. An available amount of data storage space on the data store is identified. An amount of data storage space needed is estimated for storing the shadow collection of data to the data store based on the received instruction. It is determined whether the identified available amount of data storage space is sufficient for storing the estimated amount of data storage space. The shadow collection of data is stored to the data store when said determine indicates that the identified available amount of data storage space is sufficient and the previous version is permitted to be deleted or to be overwritten.

摘要： 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 in each volume using an in-memory bitmap, while a log file and/or update sequence number journal can keep track of which files have been added to or updated. 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.
摘要翻译：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每个卷中的数据更改，而日志文件和/或更新序列号日志可以跟踪哪些文件已添加到或已更新。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。

摘要： A method for verifying data copies generated by a data protection system is provided. In accordance with the method, intents for selecting a data copy to be verified are determined. The intents may specify a time period after which data is to be verified and an interval for which the verification is to be repeated. Additionally, utilizing the intents, a data copy matching those intents is identified and verified. A data copy may be verified by comparing a checksum of the data copy with a known checksum value. If the data copy fails to be verified, a copy of the data copy is generated.
摘要翻译：提供一种用于验证由数据保护系统生成的数据副本的方法。根据该方法，确定用于选择要验证的数据副本的意图。意图可以指定要验证数据的时间段和要重复验证的间隔。另外，利用意图，识别和验证与这些意图相匹配的数据拷贝。可以通过将数据副本的校验和与已知校验和值进行比较来验证数据副本。如果数据复制无法验证，则会生成数据副本的副本。
