A method for providing access to objects associated with a particular client in a cloud storage system is disclosed. The method includes the steps of establishing a connection with a user, providing a client namespace associated with the client to the user, where the client namespace represents objects stored on the cloud storage system and objects stored on a private storage system apart from the cloud storage system, receiving a request from the user to access an object stored on the private storage system, and providing information to the user to facilitate access to the object stored on the private storage system by said user. Other systems and methods are also disclosed. Important advantages of the present invention are facilitated by separating the logic for user access (control plane) from the actual storage (Storage plane). Private file system access can still be managed from the cloud, while keeping the client data private.

Methods of cloning data backup across namespaces are disclosed. In response to receiving a file replication request, one or more source files are cloned from a first namespace to a second namespace, as one or more destination files. A first attribute indicating that the source file(s) have been cloned to the second namespace as the destination file(s) is created. A source synthetic file is cloned from the first namespace to the second namespace, as a destination synthetic file, where synthetic information of the destination synthetic file points to the source file(s) as one or more base file. A second attribute indicating that the source synthetic file has been cloned to the second namespace as the destination synthetic file is created. Based on the first and second attributes, the synthetic information of the destination synthetic file is updated or propagated to use the destination file(s) as one or more base files on the second namespace.

Data replication using an extended file replication protocol

Methods of cloning data backup across namespaces are disclosed. One or more source files are cloned from a first namespace to a second namespace, as one or more destination files. When the cloning of the source file(s) is performed, a data structure including source file information and destination file information is generated. A source synthetic file is cloned from the first namespace to the second namespace, as a destination synthetic file, where the source synthetic file uses the source file(s) as one or more base files on the first namespace. When the cloning of the source synthetic file is performed, the data structure is looked up to obtain the source file information and the destination file information. Based on the source file information and the destination file information, synthetic information of the destination synthetic file is updated to use the destination file(s) as one or more base files on the second namespace.

Data replication using synthetic relationships between files

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.
