Abstract

A method and system for enabling agentless backup and restore operations on a container orchestration platform. Specifically, the method and system disclosed herein may entail facilitating the implementation of backup (or restore) workloads in a containerized environment without the co-execution of secondary storage agents therein, which traditionally manage these backup (or restore) operations.

First claim

What is claimed is:

1. A system, comprising:
a slave node comprising a slave node manager, a container runtime, and a first computer processor;
wherein an agentless workload and job configuration information (JCI) are delegated from the slave node manager to the container runtime; and

a master node comprising a master node interface, a workload scheduler, a backup-restore controller and a second computer processor,
wherein the container runtime, when executing on the first computer processor, is programmed to perform a method, the method comprising:
receiving the agentless workload and the job JCI;
extracting, from the JCI, a container image identifier (ID);
retrieving a container image associated with the container image ID; and
instantiating, to implement the agentless workload, a job pod set comprising a container created from the container image,
wherein the container is programmed to execute a set of tasks to complete the agentless workload,
wherein the agentless workload and JCI are deployed to the slave node from the master node interface,
wherein deployment of the agentless workload and JCI to the slave node, of a plurality of slave nodes, is determined by the workload scheduler using at least a set of job resource requirements (JRR) associated with the agentless workload, and
wherein the JCI and JRR are submitted to the master node interface, by the backup-restore controller, using a job request directed to implement the agentless workload.

2. The system of claim 1 , further comprising:
a container registry operatively connected to the slave node,
wherein the container image is retrieved from the container registry.

3. The system of claim 1 , further comprising:
a cluster comprising the master node, the plurality of slave nodes, and a persistent volume pool,
wherein the persistent volume pool comprises a cluster persistent volume operatively connected to at least the slave node,
wherein the slave node comprises a cluster persistent volume mount through which the container accesses the cluster persistent volume to execute the set of tasks.

4. The system of claim 3 , further comprising:
a cluster storage system (CSS) operatively connected to the cluster,
wherein the cluster further comprises a CSS plug-in that maps the cluster persistent volume to the CSS.

5. The system of claim 3 , wherein the persistent volume pool further comprises a backup persistent volume operatively connected to at least the slave node, wherein the slave node further comprises a backup persistent volume mount through which the container accesses the backup persistent volume to further execute the set of tasks.

6. The system of claim 5 , further comprising:
a backup storage system (BSS) operatively connected to the cluster,
wherein the cluster further comprises a BSS plug-in that maps the backup persistent volume to the BSS.
