Transferring objects between different storage devices based on timestamps
Abstract:
A distributed file system includes a plurality of computing devices that are coupled to a plurality of storage devices. A first computing device transfers objects to an additional computing device. The first computing device determines times when multiple computing devices, including the first computing device, transferred objects to the additional computing device. The first computing device identifies the earliest of the times and may store this information on the additional computing devices. A second computing device resumes transferring data to the additional computing device when the first computing device becomes unavailable or inoperable. The second computing device may use the earliest of the times to determine which objects should be transferred to the additional computing device.
