Abstract
Implementations are provided for scalable cloud backup. A coordinator process can manage worker processes on nodes to package file system data that is targeted for cloud backup into node local upload objects. File data can be arranged into distinct block offsets of the node local upload object. A set of metadata tables can be generated that characterize each file that is backed up as well as file block location information for each data block. The node local upload objects can be uploaded to a cloud service provider. The set of metadata tables generated by the worker process can be coalesced into a global set of metadata tables that describe the data that has been backed up. In one implementation, after an initial cloud backup has occurred, a snapshot service of the file system can be used to incrementally backup blocks of the file that have been changed.
