An alternate name file is utilized to store alternate names, such as those associated with hard links.

A method and system are provided to automatically and transparently version files across many desktop applications without requiring the user to take specific action to cause the versioning to occur. Previous versions and versioning information can both be stored using hard links, and the versioning information can be used to determine a version history for a file. Embodiments of the present invention do not require applications to be modified to support this versioning method. Further, using one approach, the application does not even know that the versioning is occurring. The present invention provides an automatic versioning solution that is completely transparent to the user, which causes overwrite operations to be seamlessly co-opted into versioning operations which retain previous document versions instead of overwriting them.

A solution to latencies associated with server side processing time, as well as to latency resulting from the transit of information or tools from a server side to a client or user side is provided. The server side and client side can be coupled via a hard link or a network-type connection such as the Internet or a local area network. Select delta page information is stored in a concise manner on client side. As a result, the client does not have to contact the server when a user requests page information that is associated with stored delta page information. The stored delta page information can be accessed and used to update the current page thereby yielding the requested page. Thus, latency from server side processing and network transit time is reduced. An algorithm can be implemented on the client side to identify relevant stored delta page information, and to update the current page with that delta page information.

A method and system for hosting one or more virtual dedicated servers on a hosting computer system is disclosed, such that accessing the system utilities and application programs is carried out remotely via a data network.

For enabling a fast reverse lookup of parent directories storing records of hard links to a specified regular file, a file system manager maintains a hard link database (HLDB) storing information for addressing hard links to the regular files having multiple hard links. The HLDB contains a corresponding HLDB file for each regular file having multiple hard links. In a preferred implementation, the inode of each regular file stores the addressing information for one hard link to the regular file, a corresponding HLDB file stores the addressing information for other hard links to the regular file, each HLDB file is a directory accessed by invoking file system manager directory access routines, and the HLDB has a directory tree providing a multi-level hash index for searching the HLDB given the inode number of a regular file.

The system and method described herein may use reverse path lookup to build mappings between file handles that represent network file system objects and full path names associated therewith and distinguish hard links between different file system objects having the same identifier with different parents or file names. The mappings and information distinguishing the hard links may then be cached to enable replicating changes to the file system. For example, a server may search the cached information using a file handle associated with a changed file system object to obtain the file name and full path name associated therewith. The server may then send the file name and full path name and metadata describing how the file system object was changed to a replica host, which may then replicate the change to the file system object.

This disclosure describes systems, methods, and apparatus for creating or updating a table in a fully-indexed hierarchical database for storing both structured and unstructured data, where the database structure rather than separate index files provides indexing. The database includes a hierarchy of nodes where the lowest nodes represent raw data and hard links to the raw data. Data records in a table, write request, update request, etc. can be exploded into attributes and values for those attributes, and then each value is stored in a separate file at the lowest nodes of the hierarchy.

Data is migrated from an original host storage system to another replacement host storage system. An original host storage system is connected directly to the replacement host storage system.

A system and method for ingesting (capturing) digital video media files for storage on a Linux® platform-based computing environment that creates Quicktime Reference-compatible Files in the Linux® environment. Quicktime Reference-compatible Files are created such that they are labeled as not created by Avid's codec, but rather, by a native Quicktime codec. Then, via the system and method of the invention, at the time the Quicktime Reference-compatible Files are created in the Linux® environment, the system and method automatically captures the Avid file and automatically creates hard-links to those files so that the QuickTime Reference-compatible Files refer to the hard links rather than to the original Avid files. That is, rather than using the direct reference to the media files, a hard link is created to provide a second reference to them. In this manner, via said hard links (e.g., object reference), a user is permitted indirect access to all digital audio and video data that is stored in the directory on the storage device, while not requiring access to the original Avid media files. Advantageously, there is no need to convert Avid-formatted files to the Quicktime format.
