Techniques to provide mobile access to content are disclosed. A request from a mobile application running on a mobile device to access content is received at a connector node. A user credential associated with the request is used to identify at the connector node a policy associated with the request. A policy metadata associated with the policy is provided from the connector node to the mobile application running on the mobile device. The mobile application may include application code that is responsive to the policy metadata to perform, with respect to the request to access content, an action indicated by the policy.

Policy-based mobile access to shared network resources

Techniques to perform event-based synchronization of data among a plurality of endpoints are disclosed. In various embodiments, a user interaction associated with synchronization set data that has been synchronized based on synchronization events downloaded from a synchronization server configured to propagate changes via a synchronization event stream is observed. The observed user interaction is used to infer a user preference with respect to downloaded synchronization set data. Access is provided to synchronization event related data in a subsequent download in a manner determined based at least in part on the inferred user preference.

Learning client preferences to optimize event-based synchronization

Techniques to synchronize data across a plurality of endpoints are disclosed. An indication that data associated with a file or other object included in a synchronization set has been changed is received from a first synchronization endpoint associated with the synchronization set. A synchronization event that reflects the change is created and added to a synchronization event stream that is accessible to a second endpoint associated with the synchronization set.

Event-based synchronization in a file sharing environment

Techniques to perform event-based synchronization of data are disclosed. In various embodiments, a synchronization is performed at a synchronization client, based at least in part on one or more synchronization events downloaded from a synchronization server. A result of said synchronization is verified at least in part by comparing a computed representation of synchronization set state as stored at the synchronization client with a corresponding computed representation of synchronization set state as stored at the synchronization server.

Verification of event-based synchronization

Techniques to perform event-based synchronization of data are disclosed. In various embodiments, an indication is received, during the course of performing a synchronization event-based synchronization with a synchronization client, that a user of the synchronization client has provided an input associated with a request to access a file or other object the changes to which have not yet been downloaded completely to the synchronization client. Download of the changes to the file other object with respect to which the input associated with a request to access is associated is reprioritized, to enable the synchronization client to provide access to the file or other object more quickly than would have been possible without the reprioritization.

Dynamic reprioritization of content download during synchronization

Techniques to perform secure authentication to provide mobile access to shared content are disclosed. In various embodiments, a user credential associated with a request to access content is received at a connector node from a mobile application running on a mobile device. The user credential is used to create at the connector node a secure credential token that includes the user credential. The secure credential token is used to provide to the mobile application on the mobile device, via the connector node, access to content on two or more servers residing on a protected network with which the user credential is associated.

Secure authentication to provide mobile access to shared network resources

A method and system of recovery point data view shift through a direction-agnostic roll algorithm is disclosed. The method includes forming a data view around a recovery point, and shifting the data view around the recovery point through a direction-agnostic roll algorithm that uses at least one of a roll-forward algorithm to shift the data view to a time after the recovery point and a roll-backward algorithm to shift the data view to a time before the recovery point. A data integrity is determined to be consistent at the recovery point by examining data and meta-data associated with the recovery point. The recovery point is associated with one of an automatically generated event, a user definable event, and/or a prepackaged event. A marker data is generated at the recovery point to enable the direction-agnostic roll algorithm to reduce a recovery time objective when an algorithm is applied.

Recovery point data view shift through a direction-agnostic roll algorithm

Methods, software suites, and systems of generating a recovery snapshot and creating a virtual view of the recovery snapshot are disclosed. In an embodiment, a method includes generating a recovery snapshot at a predetermined interval to retain an ability to position forward and backward when a delayed roll back algorithm is applied and creating a virtual view of the recovery snapshot using an algorithm tied to an original data, a change log data, and a consistency data related to an event. The method may include redirecting an access request to the original data based on a meta-data information provided in the virtual view. The method may further include substantially retaining a timestamp data, a location of a change, and a time offset of the change as compared with the original data.

Generating a recovery snapshot and creating a virtual view of the recovery snapshot

Methods, software suites, networks, and systems of recovery point data view formation with generation of a recovery view and a coalesce policy are disclosed. In one embodiment, a network includes a virtualization module to form a data view around a recovery point, a recovery module to generate a recovery snapshot having an ability to position forward and backward from the recovery point when a rolling algorithm is applied, and an events module to generate a coalesce policy around the recovery point to reduce a storage requirement. The network may include an export module to transfer the data view to an external processing device as a virtual volume using one or more of an iSCSI and a fiber channel transport interface. The export module may automatically communicate the data view to a backup tape to provide extended data retention using a lifecycle management policy.
