PowerProtect Data Manager 19.15 Kubernetes User Guide

Notes

• You can only protect an asset with one policy at a time. Assets can move between protection policies, depending on the protection rule priorities. Protection rules do not automatically move assets that were manually added to a policy to a different policy.
• When creating a policy, limit the number of database assets within the policy to under 500 and stagger the start time of replication policies. These actions prevent potential replication failures.
• Before scheduling weekly, monthly, or yearly backups, set the PowerProtect Data Manager time zone to the local time zone. Otherwise, the backup still runs but is triggered based on the PowerProtect Data Manager time zone.
• Discovery of a Kubernetes cluster discovers namespaces that contain volumes from both container storage interface (CSI) and non-CSI based storage. However, backup and recovery are supported only from CSI-based storage. If you select a namespace from non-CSI storage, the backup fails.

  Optionally, if you want to protect a namespace that contains non-CSI storage, you can exclude the non-CSI PVC from the backup. If excluding the PVC, ensure that such a policy still meets your protection requirements.

Initial configuration

• Enable the Kubernetes asset source.
• Register the application hosts with PowerProtect Data Manager.
• Add credentials for Kubernetes assets.
• Where applicable, enable Changed Block Tracking (CBT).
• Deploy VM Direct protection engines.
• Where applicable, configure any necessary Service Level Agreements (SLAs). The PowerProtect Data Manager Administrator Guide provides instructions.

Objectives

• For replication after backup completion, PowerProtect Data Manager 19.12 or later and application agents 19.12 or later are required. It is recommended that you update the application agents to the latest version.
• To move a backup or replica to Cloud Tier, the corresponding objectives must have a retention time of 14 days or more.

Storage

• Add protection storage.

  The PowerProtect Data Manager Administrator Guide provides more information about working with storage units, such as the relationships between storage units and policies, security considerations, and applicable limitations.

• Before you add a replication objective, add remote protection storage for the replication target.
• Before you add a Cloud Tier objective, PowerProtect Data Manager requires:
  • Protection storage set up for Cloud Tier, with the system passphrase set.
  • The discovery of protection storage with a configured Cloud unit.
  • A configured and running data movement schedule on the cloud storage unit.
  The DDOS Administration Guide provides more information.

Networking

If applicable, complete all of the virtual network configuration tasks before you assign any virtual networks to the protection policy. The PowerProtect Data Manager Administrator Guide provides more information.
