Backing up data for a namespace assigned to a tenant

A system comprising:

• a processing resource;
• and
• a non-transitory computer-readable medium, coupled to the processing resource, having stored therein instructions that when executed by the processing resource cause the processing resource to:
• maintain a tenant abstraction for each tenant of a plurality of tenants of a container platform that share resources of a container cluster, wherein the plurality of tenants and a plurality of namespaces of the container cluster are not required to have a one-to-one correspondence by including, within the tenant abstraction for a given tenant of the plurality of tenants, information indicative of a subset of the plurality of namespaces assigned to the given tenant of the plurality of tenants;
• receive via a user interface of the container platform a request to backup a particular tenant of the plurality of tenants;
• and
• responsive to receipt of the request:
• determine by the container platform the subset of the plurality of namespaces assigned to the particular tenant of the plurality of tenants;
• and
• for each namespace of the subset of the plurality of namespaces, cause a namespace-level backup/recovery tool to backup object data for each namespace of the subset of the plurality of namespaces within a backup location, and backup data associated with persistent volume claims for each unit of cluster replication within each namespace.

A non-transitory machine readable medium storing instructions, which when executed by a processing resource of a computer system, cause the processing resource to:

• maintain a tenant abstraction for each tenant of a plurality of tenants of a container platform that share resources of a container cluster, wherein the plurality of tenants and a plurality of namespaces of the container cluster are not required to have a one-to-one correspondence by including, within the tenant abstraction for a given tenant of the plurality of tenants, information indicative of a subset of the plurality of namespaces assigned to the given tenant of the plurality of tenants;
• receive via a user interface of the container platform a request to backup a particular tenant of the plurality of tenants;
• and
• responsive to receipt of the request:
• determine by the container platform the subset of the plurality of namespaces assigned to the particular tenant of the plurality of tenants;
• and
• for each namespace of the subset of the plurality of namespaces, cause a namespace-level backup/recovery tool to backup object data for each namespace of the subset of the plurality of namespaces within a backup location, and backup data associated with persistent volume claims for each unit of cluster replication within each namespace.
