Abstract:
Provided are techniques for transferring data. It is determined whether an indicators map is to be associated with a source file that is being opened, wherein the indicators map indicates which source blocks of the source file have been updated since last being transferred to a target file. In response to determining that an indicators map is to be associated with the source file, it is determined whether the indicators map exists. In response to determining that the indicators map exists, it is determined whether the indicators map is to be trusted based on a last modified time and a last source file size stored in the indicators map and the source file. In response to determining that the indicators map is to be trusted, the indicators map is initialized. Then, in response to receiving a write for the source file, the indicators map is updated to indicate which portion of the source file has been modified.

US Classification:
711162, 707205, 707E1701
Abstract:
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.
