Using cloud storage as temporary cache for backup
Systems and methods are described to transfer content from a first computing device to a second computing that is not directly accessible from the first computing device. The transfer may be carried out using an application operating on the first computing device that uploads the content to the cloud storage service. The second computing device may operate an application that monitors the cloud storage service for recently uploaded content. When the second computing device detects that content has been uploaded to the cloud storage service, the second computing device may download the content. The second computing device may update a manifest file located on the cloud storage service to indicate that the content was downloaded. Subsequently, the first computing device may access the manifest file and determine that content was downloaded.
