Abstract: Methods and systems are disclosed for backup using a metadata virtual hard drive (VHD) and a differential VHD. A particular system includes a memory device that stores files and a backup agent configured to detect changes to the files. The system includes a translation module configured to translate the detected changes into VHD formatted changes and a VHD module configured to write the VHD formatted changes to a metadata VHD stored at the memory device. The VHD module is also configured to generate a differential VHD based on the metadata VHD. A network interface at the system is configured to transmit the metadata VHD and the differential VHD to a remote storage device.

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.

Abstract translation: 本发明的实施方式提供被配置为在复制周期期间，在那些有效卷影副本已经到期之前，保存有效卷影副本的系统，方法和组件。 特别是，一个或多个组件可以识别将应用于新卷卷影副本的生产服务器数据更改的大小和速率。 然后，组件可以确定将新卷卷影副本存储在备份卷中时所需的存储区域，并在有适当空间时将更改应用到备份卷上。 如果没有适当的空间量，组件可以通知系统应该采取新的操作来保留之前有效的卷影副本以及新的卷影副本。 例如，备份管理员可能需要增加卷影副本存储空间，或者指定新的存储介质来处理新的卷影副本。
