Publication number: US20150067706A1
Application number: 14/538,439

Various embodiments of a system and method for providing input/output virtualization for a file are disclosed. The system may include a filter program that intercepts a write request for a particular file and stores change information specifying the data and the write location indicated by the write request. However, the file itself is not modified. The filter program may also intercept a read request referencing the file and determine whether change information representing a write request to write data at the location specified by the read request has been previously stored. If so then the data specified by the change information is returned in response to the read request.

A method, system and computer-readable medium for providing rapid failback of a computer system is described. The method, which operates during failback of a secondary computer to a primary computer, accesses a map to determine a location of a latest version of data corresponding to a read request, where the location may be within either a primary data storage or a secondary data storage. The system comprises a primary computer coupled to a primary data storage and a secondary computer coupled to a secondary data storage. The primary computer maintains a write log and the secondary computer maintains a map. The computer-readable medium contains instructions, which, when executed by a processor, performs the steps embodied by the method.

Application number: 14/043,111

A method, system and apparatus for assembling and publishing frequent malware signature definition updates through the use of additive or “streaming” definition packages is provided. Embodiments of the present invention provide such functionality by publishing not only full malware signature definition updates on a long periodicity but also streaming malware signature definition updates containing newly certified signature definitions on a short periodicity. As newly-certified malware signature definitions are received, those newly-certified signature definitions are incorporated not only in the full signature definition file but also in a streaming signature definition update that contains only newly-certified signature definitions received during a streaming update period. At the end of the streaming update period, a streaming signature definition file is made available by publication to anti-malware clients. A streaming signature definition file only contains those signature definitions received during the assembly period for that streaming definition file.
