Abstract
Embodiments for balancing cloud resource capacity for cross-node movement of files in a scaled out backup system, and for dynamically allocating cloud storage resources in a multi-node network having a file system. A process determines a destination node with dedicated cloud storage capable of storing a file selected for long term retention. It transfers the file to the cloud storage of the destination node while maintaining metadata of the file in the cloud tier local storage of the destination node, such as by using remote procedure calls between the destination and source nodes. It then updates a global namespace of the file system with a handle indicating a current location of the file as the cloud storage of the destination file, thus allowing access to the file through the metadata stored in the local storage of the source node.
