A technique is described providing offline support to business applications. Offline support allows a business application running on a portable electronic device without connectivity to a backend server to operate as though the business application has access to a backend server. The technique receives a sync request for content from the portable electronic device. A sync task is generated from the sync requests and processed to generate a package that contains the desired content. Once the package is generated, the package is stored in a package repository and a download notification is transmitted to the portable electronic device to notify the user that the package is ready. The package can in turn be delivered to the portable electronic device when a download request is received from the portable electronic device.

Asynchronous download for application offline support

Transmitting or storing subsegments is disclosed. A data stream or a data block is received and broken into a plurality of segments. For at least one segment, the segment is broken into a plurality of subsegments. A previously stored or transmitted segment similar to the at least one segment is identified. A fingerprint is computed for at least one subsegment. And, using the fingerprint for the at least one subsegment, determining whether the at least one subsegment is identical to a subsegment of the previously stored or transmitted segment without directly comparing the content of the at least one subsegment with the content of the subsegment of the previously stored or transmitted segment.

Subsegmenting for efficient storage, resemblance determination, and transmission

Determining a summary feature set is disclosed. A plurality of subsegments of a first segment are selected. For each subsegment, a plurality of values by applying a set of functions to each subsegment are computed. From all the values computed for all the subsegments, a first subset of values is selected.

Efficient computation of sketches

Stream locality delta compression is disclosed. A previous stream indicated locale of data segments is selected. A first data segment is then determined to be similar to a data segment in the stream indicated locale.

Stream locality delta compression

A method of managing duplicate segments from a segmented file storage system is disclosed. The method comprises indexing a segment according to a key for the segments wherein the index includes an identification of a first data location where the segment is stored and identifying a duplicate segment having the same key that is stored in a second location. The method further comprises determining that the duplicate segment is an undesired duplicate segment and eliminating the undesired duplicate segment.

Duplicate management

A system and method are disclosed for providing efficient data storage. A plurality of data segments is received in a data stream. The system determines whether a data segment has been stored previously in a low latency memory. In the event that the data segment is determined to have been stored previously, an identifier for the previously stored data segment is returned.

Efficient data storage system

Data replication with delta compression is disclosed. A primary system and a replica system are determined to both have an identical first data segment that is similar to a second data segment. The second data segment is encoded, wherein the encoding refers to the first data segment.

Data replication with delta compression

A technique is described providing offline support to business applications. Offline support allows a business application running on a portable electronic device without connectivity to a backend server to operate as though the business application has access to a backend server. The technique receives a client request to operate the application in an offline mode. The technique then retrieves a business object to be utilized in the offline mode and an event trigger for interacting with the business object. The native programming language is then determined and then an event handler written in a native language of the client device and that is associated with the event trigger is retrieved. The event trigger is then modified to point to the event handler. The business object, event trigger, and event handler are then packaged together.

Packaging application data and logic for offline support

A system and method are disclosed for providing efficient data storage. A plurality of data segments is received in a data stream. The system preliminarily checks in a memory having a relatively low latency whether one of the plurality of data segments may have been stored previously in a data segment repository. The memory having the relatively low latency stores data segment information. In the event that the preliminary check determines that one of the plurality of data segments may have been stored in the data segment repository, a memory having a relatively higher latency is checked to determine whether the data segment has been stored previously in the data segment repository.

Delta compression after identity deduplication is disclosed. A first data segment is determined to be identical to a first previous data segment. A second data segment, not determined to be identical to a second previous data segment, is then determined to be similar to a third previous data segment.
