SYSTEM AND PROGRAM FOR REPLICATING A FILE |
摘要 |
Provided are a method, system, and program for replicating a file. A file is copied to a target storage file system stored as a base file. A reference file comprising the copied file is generated at a local storage. An update is applied to the file at the local storage. A delta file is generated indicating differences between the updated file at the local storage and the reference file. A file system command is used to transmit the delta file to the target storage file system store to store in a directory of the target storage file system, wherein the file in the local storage is replicated at the target storage by a combination of the base file and the delta file.
