KDMP backup prerequisites​

If you need to initiate KDMP or cross-cloud backups, ensure that you allocate additional buffer storage that is double the size of the original Persistent Volume Claim (PVC) in your application cluster. This buffer ensures that there is sufficient storage allocation for data changes, snapshots, or temporary data generated during the backup process.

Prometheus prerequisites​

If you have your own Prometheus installed cluster-wide, ensure that it does not reconcile with the Portworx Backup Prometheus in px-backup namespace.

When Prometheus and Alertmanager are in CrashLoopBackOff state, ensure the that the global or cluster wide Prometheus Operator does not interfere with the Prometheus and Alertmanager instances in px-backup namespace. If so, modify the cluster-wide Prometheus operator to exclude the namespace where the Portworx Backup Prometheus stack is installed.

Add the following entry under spec.template.spec.containers[0].args in the cluster-wide Prometheus Operator spec to resolve conflicts if any:

--deny-namespaces=<px-backup-installed-namespaceName

Alternatively, you can also set the scope of the cluster-wide Prometheus to defined namespace using the below parameter:

-- namespaces = <namespace where cluster-wide prometheus is installed>
note

Portworx Backup 2.3.0 and above use MongoDB 5.x versions internally, which require Intel/AMD Chipsets that support Advance Vector Extensions (AVX). If you are deploying Portworx Backup 2.3.0 and above, please ensure that your Intel/AMD Chipset versions support AVX.
