摘要： Methods, apparatuses, and systems directed to improving shared file access in wide area network file systems. In a particular implementation, one or more elements of a wide area file system cooperate to keep an original file intact on a remote file server until a new copy of the same file is flushed to the remote file server. In a particular implementation, rename operations identifying a source and a target in connection with application-level save operations are executed as two composite operations including creation of the target, and a delayed deletion of the source. The delay after which the source is deleted can be configured to be just large enough so that the application save operation on a local cache can be completed.

摘要： The present invention, in particular embodiments, provides methods, apparatuses and systems directed to providing a Wide Area File System that is robust against network connectivity issues. In particular implementations, the present invention provides a WAFS disconnected-mode read-write access that provides for a more seamless user experience against WAN or other network connectivity failures. Specific embodiments provide for management, at a network device such as an EFG node, of file objects previously opened during a connected state with a remote file server appliance, creation of new file objects during a disconnected state and re-synchronization of those file objects (data and meta-data) when a connection becomes available.

摘要： Methods, apparatuses, and systems directed to reducing network traffic and processing overhead associated with directory refresh operations in wide area network file systems. In a particular implementation, the frequency of synchronization of certain directory contents information, such as security attribute information, that changes less frequently is reduced relative to other types of directory contents information that changes more frequently, such as file and folder names, last modified times, and the like. Other implementations reduce garbage collection overhead for a cached file system by deferring deletion of invalidated objects in a directory until a client application specifically identified the directory.

摘要： The present invention, in particular embodiments, is directed to methods, apparatuses and systems that provide an efficient compression technique for data streams transmitted to storage devices or over networks to remote hosts. Local storage as well as network transmission of streams is made more efficient by awareness and utilization of repeated sequences of data blocks. Such data blocks can be placed in a dictionary on persistent storage and shared across all streams. The dictionary is hierarchically indexed (two or more levels of indexing) to combine high efficiency search with efficient access to the stored data blocks. Additionally, data blocks, in particular implementations, are stored sequentially in order to improve overall performance.
