A computer-implemented system configured to describe the relationship between a first Namespace and a second Namespace is provided. The system includes a containment relationship identifying a direct relationship between a first object of the first Namespace and a second object of the first Namespace. Moreover, the system includes a junction relationship linking the second object of the first Namespace to a first object of the second Namespace. In one embodiment, the system is configured to facilitate the recovery of information based on the descriptions of the Namespaces that is maintained.

Configuring a data protection system

A method for creating an archive protection plan for archiving a backup of data is provided. An indication of an archive data protection kind and an archive data protection duration are received. In response to receiving the archive data protection kind and the archive data protection duration, an archive scheme is determined and an archive protection plan representative of the archive scheme is generated.

Method, system, and apparatus for creating an archive routine for protecting data in a data protection system

A method for creating a group plan for protecting an object located at a production location is provided. A selection of an object for which a group plan is to be created is received along with protection intents for the selected object. The protection intents are translated into a group plan for protecting the selected object.

A backup administrator can backup files from a production server on any of a plurality of different bases. In particular, some files can be replicated on a changed-byte basis. In other cases, files can be backed up by replicating updated copies of the entire file, or even byte blocks of the file. Determinations as to how a replication agent will back up a certain file or set of files can be made by a backup administrator, automatically through a predefined logic, or dynamically based on defined criteria. Corresponding agents at the production server can then flag these files as indicated. Thus, at a later point, when the DPM server requests the updates of each file, the production server can either send over copies of the changed file bytes, entire copies of the changed file itself, or even changed blocks of a file, as appropriate.

Automatically determining file replication mechanisms

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.

Creating frequent application-consistent backups efficiently

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.

A method for protecting protectable objects located at a production location is provided. A Namespace, representative of a plurality of protectable objects, is provided to a user for selection. A selection of at least a portion of the Namespace is received and that selected portion is mapped to at least one protectable object. A plan for protecting the mapped protectable object is created, and using that plan the protectable object is protected.

A backup system in accordance with an implementation of the present invention includes one or more light-weight (i.e., stateless) storage nodes that are positioned close enough to one or more assigned production servers to enable as rapid and efficient a data recovery as possible. The one or more light-weight storage nodes are driven by, and implement backup policies in accordance with, control settings determined by and received from a centralized backup server. Changes to the control settings are simply produced at the centralized backup server and propagated to each storage node in the system. In addition to efficient backup times, general backup administration can be greatly simplified at least in part since a large number of production serves can be serviced through a small or large number of light-weight storage nodes, which in turn can be managed by a single centralized backup server.

Managing backup solutions with light-weight storage nodes

A data protection application if provided. The data protection application includes a job for providing protection to data. That job contains a plurality of tasks configured to perform the job. Also included is a task executor for managing the progress of each of the plurality of tasks.
