Implementations are described of a computing device that migrates data and software applications from a first computing device to a second computing device, in order to preserve data and other application-related customizations.

Logical migration of applications and data

An archive of items, which are computing data accessed by a user, is created at a semantic object level. The object archiving may group seemingly disparate items as a composite object, which may then be stored to enable retrieval by the user at a later point in time. The composite object may include metadata from the various items to enable identifying the composite object and providing retrieval capabilities. In some aspects, an archiving process may extract item data from an item that is accessed by a computing device. Next, the item may be selected by a schema for inclusion in a composite object when the item data meets criteria specified in the schema. The composite object(s) may then be stored in an object store as an archive.

Backup and archival of selected items as a composite object

The claimed subject matter provides a system and/or a method that facilitates seamless integration of a data storage service within an operating system (OS). An online safe deposit box can store a portion of data, wherein the online safe deposit box is hosted by a data storage service provider. A local operating system associated with a device can leverage a graphic user interface (GUI) to interact with a portion of data associated with the device. A map component can create a mapped drive that integrates the online safe deposit box within the local operating system to enable seamless data interaction between the local operating system and the online safe deposit box, wherein the data interaction is at least one of a data upload from the local operating system to the online safe deposit box or a data download from the online safe deposit box to the local operating system.

Online virtual safe deposit box user experience

The claimed subject matter provides a system and/or a method that facilitates integration of a distributed backup environment and a online backup environment. A super peer device can be designated from a set of peer devices. The super peer can distribute backup data amongst the set of peer devices based upon availability and storage capacity of the peer devices. In addition, the super peer can transfer portions of backup data from the set of peers to an online backup service.

Hybrid distributed and cloud backup architecture

The claimed subject matter provides a system and/or a method that facilitates employing a safe deposit box that allows perpetual archiving of data. An online safe deposit box can store a portion of data, wherein the online safe deposit box is hosted by a data storage service provider. An archival model component can implement the online safe deposit box for perpetual archival of the portion of data. The archival model component can ensure at least one of the following: the online safe deposit retains the portion of data for a pre-defined duration; the portion of data within the online safe deposit box is accessible solely by an authorized entity; or the integrity of the portion of data is maintained, wherein the integrity is modified solely by an authorized user.

Virtual safe deposit box for perpetual digital archival

Provided herein are systems and methodologies for highly efficient restoration in a network-based backup system. As described herein, differential-based analysis can be utilized such that a new complete differential is calculated based on signatures and/or other information relating to a given item to be restored prior to retrieving backup data. Based on the differential, only blocks determined to be unique between the current version of the item and the desired version are transmitted, which can then be merged with non-unique locally present blocks to obtain the fully restored version of the item. Further, a hybrid architecture can be employed, wherein signatures and/or data are stored at a global location within a network as well as one or more local peers. Accordingly, a backup client can obtain information necessary for restoration from either the global location or a nearby peer, thus further reducing latency and bandwidth consumption.

Differential file and system restores from peers and the cloud

The claimed subject matter provides a system and/or a method that facilitates distributed backup and versioning techniques for network-based backup architectures. When data is committed to a backup system, a backup version can be created. The generated backup version can be a complete rendition of data or the generated backup version can be a differential between the data and backup information previously committed to the system. The generated backup version can be replicated across a distributed network of peers. Replication can be based upon a desire level of redundancy of versions, location of peers, network topology of peers, storage capacity of peers, health of peers, type of peer, and the like. In addition, versions can be retained based upon a configurable number of desired versions.

Distributed backup and versioning

The claimed subject matter relates to an architecture that can determine costs associated with updating file formats. In particular, the architecture can interface with a network-accessible data storage service in order to determine a cost-benefit to the data storage service for a wide variety of conversion scenarios applicable to the particular topology of the data storage service. For example, the cost-benefit can differ for storage services configured according to a client-server model relative to storage services configured according to a distributed topology. Regardless, the architecture can identify a legacy format, select a converter for converting the legacy format to the updated format, and then determine the cost-benefit for a variety of conversion or migration scenarios.

Mitigation of obsolescence for archival services

The claimed subject matter relates to a network-accessible, online data archival service with a data store for archiving data for clients of the archival service. The archival service can include an architecture that can facilitate perpetual sustainability and accessibility of data by conforming to a model. In particular, the model can describe or define a minimum set of extensible or pluggable components or modules needed to facilitate and guarantee sustainability of and accessibility to the data in perpetuity.

Perpetual archival of data

Implementing a consistent user name-space on networked computing devices includes various components and methods. When a network connection between a local or host computing device and one or more remote computing devices is present, remote items are represented using the same methodology as items located on the host computing device. To the user, remote and local items are indistinguishable. When the network connection is lost or items located on a remote computer are otherwise unavailable, the unavailable items remain represented on the host computing device. Unavailable items are represented in a way that informs the user that the items may not be fully accessed.

When a network connection between a local or host computing device and one or more remote computing devices is present, remote items are represented using the same methodology as items located on the host computing device. To the user, remote and local items are indistinguishable.

System and method for generating a consistent user namespace on networked devices

The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e.g., client) and/or the client applications across connectivity interruptions and/or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.
