    摘要: A computer-implemented method includes creating a first snapshot of at least one virtual machine at a first time. The first snapshot is created at a computing device of a cluster of computing devices configured to share the at least one virtual machine. As an example, each computing device in the cluster may modify the shared virtual machine via a direct input/output (I/O) transaction, bypassing a file-system stack. The first snapshot is transmitted to a backup device. The method includes creating a second snapshot of the at least one virtual machine at a second time and determining a set of changed data blocks associated with a difference between the second snapshot and the first snapshot. The set of changed blocks is transmitted to the backup device.

    摘要: Aspects of the subject matter described herein relate to a storage architecture. In aspects, an address provided by a data source is translated into a logical storage address of virtual storage. This logical storage address is translated into an identifier that may be used to store data on or retrieve data from a storage system. The address space of the virtual storage is divided into chunks that may be streamed to the storage system.

    摘要: 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.

    摘要: In accordance with one embodiment of the present invention, a method for efficiently inventorying a plurality of items of media contained in a library is provided. The method includes reading a barcode located on an item of media that contains contents and determining whether the barcode is known. Optionally, the method may also determine if the know item of media was previously offline. If it is determined that the barcode is known, the media is identified as known. However, if it is determined that the barcode is not known, a detailed inventory of the contents of the item of media is performed. In one embodiment, if it is determined that the barcode is not known, a user is notified that a new item of media has been identified.

    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.
