Data replication using an extended file replication protocol

A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations of replicating synthetic data backup across namespaces, the operations comprising:

• in response to receiving a file replication request, cloning one or more source files from a first namespace to a second namespace, as one or more destination files;
• creating a first attribute indicating that the one or more source files have been cloned to the second namespace as the one or more destination files;
• cloning one or more source synthetic files from the first namespace to the second namespace, as one or more destination synthetic files, wherein each source synthetic file of the one or more source synthetic files includes at least one data segment from a source file and incremental data associated with the source file, and respective synthetic information of the one or more destination synthetic files respectively point to the one or more source files as one or more base files on the first namespace;
• creating a second attribute indicating that the one or more source synthetic files have been cloned to the second namespace as the one or more destination synthetic files;
• and
• based on the first and second attributes, updating the respective synthetic information of the one or more destination synthetic files to respectively point to the one or more destination files as one or more base files on the second namespace, wherein each destination synthetic file of the one or more destination synthetic files includes at least one data segment from a destination file and incremental data associated with the destination file;
• wherein the updating the respective synthetic information of the one or more destination synthetic files comprises changing one or more base file parameters in the respective synthetic information of the one or more destination synthetic files to respectively point to the one or more destination files.

A data processing system for replicating synthetic data backup across namespaces, the data processing system comprising:

• a processor;
• and
• a memory coupled to the processor to store instructions, which when executed by the processor, cause the processor to perform operations, the operations including;
• in response to receiving a file replication request, cloning one or more source files from a first namespace to a second namespace, as one or more destination files;
• creating a first attribute indicating that the one or more source files have been cloned to the second namespace as the one or more destination files;
• cloning one or more source synthetic files from the first namespace to the second namespace, as one or more destination synthetic files, wherein each source synthetic file of the one or more source synthetic files includes at least one data segment from a source file and incremental data associated with the source file, and respective synthetic information of the one or more destination synthetic files respectively point to the one or more source files as one or more base files on the first namespace;
• creating a second attribute indicating that the one or more source synthetic files have been cloned to the second namespace as the one or more destination synthetic files;
• and
• based on the first and second attributes, updating the respective synthetic information of the one or more destination synthetic files to respectively point to the one or more destination files as one or more base files on the second namespace, wherein each destination synthetic file of the one or more destination synthetic files includes at least one data segment from a destination file and incremental data associated with the destination file;
• wherein the updating the respective synthetic information of the one or more destination synthetic files comprises changing one or more base file parameters in the respective synthetic information of the one or more destination synthetic files to respectively point to the one or more destination files.
