METHOD OF EFFICIENT BACKUP OF DISTRIBUTED FILE SYSTEM FILES WITH TRANSPARENT DATA ACCESS

METHOD OF EFFICIENT BACKUP OF DISTRIBUTED FILE SYSTEM FILES WITH TRANSPARENT DATA ACCESS

Examples include techniques for backing up a file to long term "cold" storage by using circuitry, and logic for execution by the circuitry, to receive a request to back up the file in a distributed file system to cold storage, to copy the file from at least one data node of the distributed...

Zusammenfassung:Examples include techniques for backing up a file to long term "cold" storage by using circuitry, and logic for execution by the circuitry, to receive a request to back up the file in a distributed file system to cold storage, to copy the file from at least one data node of the distributed file system to cold storage, to set a location of the file in cold storage in a name node of the distributed file system, and to set a length of the file to zero in the name node.
