Techniques for proving authenticity of data files, such as digital photos. An authentication/indexing server content from a client device such as a mobile device, and generates or receives other related data such as a reference to the content object, a fingerprint for the content object, and other metadata indicating for example a timestamp related to the content object. The fingerprint is inserted into a distributed ledger, with the distributed ledger returning a ledger address. A manifest object containing the transaction object, the ledger address, and a list of the content object and, optionally, related edits is then created and stored. The server may index fingerprints. Thus, a fingerprint can be used to authenticate subsequently received object against the stored metadata.

Atomic capture of a set of related files, using a distributed ledger, for proof of authenticity

A digital asset is represented and verified as a set of related digital asset or other content objects. Related metadata is stored on an immutable distributed ledger separately from the content objects themselves. For example, a transaction object includes metadata such as identifiers for two or more content objects, fingerprints for the content objects. The content objects may be stored in a local or cloud object repository. Validation of a later identified content object may include determining a fingerprint for the later identified content object, mapping that fingerprint to an address within the immutable distributed ledger to retrieve metadata previously mapped, and comparing the two fingerprints. Visual validation may be provided when the first and second fingerprints match, such as by displaying a positive icon adjacent the later identified object.

Real time visual validation of digital content using a distributed ledger

A method for assessing the risk and cost for data loss and disaster recovery (DR) plans includes providing an application having a graphical user interface (GUI) comprising first and second windows arranged adjacent to each other. The first window comprises a catalog of components used to generate data disaster recovery (DR) configurations and the second window displays the generated DR configurations. A first DR configuration is generated in the second window and components are added to the first DR configuration by dragging and dropping components from the catalog into appropriate locations of the second window. Metrics for the first DR configuration are calculated and reported in the second window. A second configuration is also similarly generated in the second window and the metrics results are graphically compared to each other.

Method for data disaster recovery assessment and planning

A cloud storage gateway is used to migrate a volume from a source cloud storage provider to a target cloud storage provider. If necessary, the gateway reconfigures the size of a logical cache associated with local storage devices so that the entire volume can be stored locally. Flushing is disabled and all of the locally stored volume pages are marked as dirty. After compression and encryption policies associated with the source and target are verified to be compatible, flushing is enabled and metadata is updated.

Cloud-to-cloud data migration via cache

Described are computer-based methods and apparatuses, including computer program products, for non-disruptive data path modification using target mobility. A management server is in communication with a switching fabric. The switching fabric is in communication with a host and a data storage element. The management server creates a takeover target based on a primary target, where the primary target is part of a virtual data path between the host and the data storage. The switching fabric, through the direction of the server, modifies metadata associated with the virtual data path to expose the takeover target so that the takeover target becomes part of the virtual data path. The management server unexposes the primary target so that the primary target is no longer part of the virtual data path. The delay between exposing the takeover target and unexposing the primary target is sufficiently small to prevent an error condition from occurring at the host.
