Abstract: 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.
