Abstract
A method in a processing system for managing backup data on a set of nodes in a network data processing system. An inventory of files is generated on a set of nodes in the network data processing system. An initial map from the inventory is created, wherein the first initial map includes an identification of each file located on a node in the set of nodes. A location map is built from the initial map and the location map identifies a set of files and identifies each node on which a file in the set of files is located, wherein at least one node in the set of nodes is a peer node to another node in the set of nodes.
Claims22
A method in a processing system for managing backup data on a set of nodes in a network data processing system, the method comprising:
- generating an inventory of files on the set of nodes in the network data processing system;
- creating an initial map from the inventory, wherein the first initial map includes an identification of each file located on a node in the set of nodes;
- and
- building the location map from the initial map, wherein the location map identifies a set of files and identifies each node on which a file in the set of files is located, wherein at least one node in the set of nodes is a peer node to another node in the set of nodes.
A data processing system in a processing system for managing backup data on a set of nodes in a network data processing system, the data processing system comprising:
- generating means for generating an inventory of files on the set of nodes in the network data processing system;
- creating means for creating an initial map from the inventory, wherein the first initial map includes an identification of each file located on a node in the set of nodes;
- and
- building means for building the location map from the initial map, wherein the location map identifies a set of files and identifies each node on which a file in the set of files is located, wherein at least one node in the set of nodes is a peer node to another node in the set of nodes.
A computer program product in a processing system for managing backup data on a set of nodes in a network data processing system, the computer program product comprising:
- first instructions for generating an inventory of files on the set of nodes in the network data processing system, wherein at least one node in the set of nodes is a peer node to another node in the set of nodes;
- second instructions for creating an initial map from the inventory;
- and
- third instructions for building the location map from the initial map, wherein the location map identifies a set of files and identifies each node on which a file in the set of files is located, wherein the first initial map includes an identification of each file located on a node in the set of nodes.
A data processing system comprising:
- a bus;
- a communications unit connected to the bus;
- a memory connected to the bus, wherein the memory includes a set of instructions;
- and
- a processor unit connected to the bus, wherein the processor unit executes the set of instructions to generate an inventory of files on the set of nodes in the network data processing system;
- create an initial map from the inventory, wherein the first initial map includes an identification of each file located on a node in the set of nodes;
- and build the location map from the initial map, wherein the location map identifies a set of files and identifies each node on which a file in the set of files is located, wherein at least one node in the set of nodes is a peer node to another node in the set of nodes.
