Patent attributes
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.
