Abstract

Provided are a system and article of manufacture for performing scheduled backups of a backup node associated with a plurality of agent nodes. Backup data sets on at least one machine in a network are associated with a backup node and a plurality of agent nodes in the network are associated with the backup node. The agent nodes are associated with machines in the network capable of backing up the backup data sets associated with the backup node. A schedule indicating a scheduled backup to backup scheduled data sets associated with the backup node is processed. At least one of the agent nodes is contacted to request the at least one agent node to perform the scheduled backup and backup the scheduled data sets, wherein the at least one contacted agent node performs the scheduled backup to backup the scheduled backup sets.

Claims

1. A method, comprising:

associating backup data sets on at least one machine in a network with a backup node;

associating a plurality of agent nodes in the network with the backup node, wherein the agent nodes comprise machines in the network capable of backing up the backup data sets associated with the backup node;

processing a schedule indicating a scheduled backup to backup scheduled data sets associated with the backup node;

contacting at least one of the agent nodes to determine whether the agent node is available to perform the scheduled backup;

assigning the scheduled backup to the contacted agent node in response to determining that the agent node is available to perform the scheduled backup; and

contacting the at least one of the agent nodes assigned the scheduled backup over the network to request the at least one contacted agent node assigned the scheduled backup to perform the scheduled backup and backup the scheduled data sets, wherein the at least one contacted agent node assigned the scheduled backup performs the scheduled backup to backup the scheduled backup sets.

2. The method of claim 1, wherein the backup node comprises a virtual node, and wherein at least one backup data set associated with the backup node is implemented within one node on the network that is different from at least one agent node associated with the backup node.

3. The method of claim 1, wherein the scheduled data sets are located on storage devices in the network, wherein the agent nodes backup the scheduled data sets by communicating with the storage devices over the network to cause a transfer of the scheduled data sets from the storage devices to backup storage.

4. The method of claim 1, further comprising:

indicating that one of the agent nodes is not available to perform the scheduled backup in response to determining that the agent node is not available to perform the scheduled backup, wherein the agent node indicated as not available is not contacted during a subsequent processing of the scheduled backup.

5. The method of claim 1, wherein selecting the at least one agent mode comprises:

selecting multiple agent nodes to perform the scheduled backup; and

assigning a portion of the scheduled data sets to each of the selected agent nodes to perform the scheduled backup with respect to the assigned portion.

6. The method of claim 1, wherein the at least one agent node performing the scheduled backup acts on behalf of the backup node when performing the scheduled backup operations.

7. The method of claim 1, wherein the contacting the at least one agent node to determine whether the agent node is available to perform the scheduled backup comprises:

selecting one agent node according to a serial ordering of the agent nodes, wherein the selected agent node comprises the contacted agent node; and

until one selected agent node is found to be available to perform the scheduled backup, selecting a next agent node according to the serial ordering to contact to determine whether the next agent node is available to perform the scheduled backup in response to determining that a previously selected agent node is not available to perform the scheduled backup.

8. The method of claim 1, wherein the contacting the at least one agent node to determine whether the agent node is available to perform the scheduled backup comprises:

broadcasting a message to multiple of the agent nodes to determine which agent nodes are available to perform the scheduled backup; and

selecting multiple of the agent nodes that are determined to be available to perform the scheduled backup as a result of the broadcasted messages to perform assigned portions of the scheduled backup.

9. A system in communication with machines over a network, wherein a plurality of agent nodes comprise the machines in the network, comprising:

a processor; and

a computer readable medium include code capable of causing the processor to perform operations, the operations comprising;

associating backup data sets on at least one of the machines in the network with a backup node;

associating a plurality of agent nodes in the network with the backup node, wherein the agent nodes are capable of backing up the backup data sets associated with the backup node;

processing a schedule indicating a scheduled backup to backup scheduled data sets associated with the backup node;

contacting at least one of the agent nodes to determine whether the agent node is available to perform the scheduled backup;

assigning the scheduled backup to the contacted agent node in response to determining that the agent node is available to perform the scheduled backup; and

contacting the at least one of the agent nodes assigned the scheduled backup over the network to request the at least one contacted agent node assigned the scheduled backup to perform the scheduled backup and backup the scheduled data sets, wherein the at least one contacted agent node assigned the scheduled backup performs the scheduled backup to backup the scheduled backup sets.

10. The system of claim 9, wherein the backup node comprises a virtual node, and wherein at least one backup data set associated with the backup node is implemented within one node on the network that is different from at least one agent node associated with the backup node.

11. The system of claim 9, wherein the system is in communication with storage devices in the network, wherein scheduled data sets are located on the storage devices in the network, wherein the agent nodes backup the scheduled data sets by communicating with the storage devices over the network to cause a transfer of the scheduled data sets from the storage devices to backup storage.

12. The system of claim 9, wherein the operations further comprise:

indicating that one of the agent nodes is not available to perform the scheduled backup in response to determining that the agent node is not available to perform the scheduled backup, wherein the agent node indicated as not available is not contacted during a subsequent processing of the scheduled backup.

13. The system of claim 9, wherein selecting the at least one agent mode comprises:

selecting multiple agent nodes to perform the scheduled backup; and

assigning a portion of the scheduled data sets to each of the selected agent nodes to perform the scheduled backup with respect to the assigned portion.

14. The system of claim 9, wherein the at least one agent node performing the scheduled backup acts on behalf of the backup node when performing the scheduled backup operations.

15. The system of claim 9, wherein the contacting the at least one agent node to determine whether the agent node is available to perform the scheduled backup comprises:

selecting one agent node according to a serial ordering of the agent nodes, wherein the selected agent node comprises the contacted agent node; and

until one selected agent node is found to be available to perform the scheduled backup, selecting a next agent node according to the serial ordering to contact to determine whether the next agent node is available to perform the scheduled backup in response to determining that a previously selected agent node is not available to perform the scheduled backup.
