Policy Presets
A PolicyPreset custom resource (CR) is used to save and reuse configuration of Veeam Kasten Policies. Follow this page to learn more about using Veeam Kasten Policy Presets.
A PolicyPreset specifies schedule, retention, location and infrastructure information, while Policy that uses a preset is supposed to specify application specific information. A detailed description of the schedule settings can be found in the Policy Scheduling section.
For complete documentation of the PolicyPreset CR, refer to PolicyPreset API Type.
Example PolicyPreset Operations
Create a PolicyPreset
The following example illustrates how to create a preset for policies which execute hourly, retain 24 hourly and 7 daily snapshots and export every daily snapshot with the same retention schedule as for snapshots (i.e. retain 7 daily exported snapshots).
$ cat > sample-policy-preset.yaml <<EOF
apiVersion: config.kio.kasten.io/v1alpha1
kind: PolicyPreset
metadata:
name: sample-policy-preset
namespace: kasten-io
spec:
comment: My sample policy preset
backup:
frequency: '@hourly'
retention:
hourly: 24
daily: 7
export:
frequency: '@daily'
exportData:
enabled: true
profile:
name: my-location-profile
namespace: kasten-io
EOF
$ kubectl apply -f sample-policy-preset.yaml
policypreset.config.kio.kasten.io/sample-policy-preset created
# make sure it initializes and validates properly
$ kubectl get policypresets.config.kio.kasten.io --namespace kasten-io -w
NAME STATUS AGE
sample-policy-preset Success 32s
Update a PolicyPreset
To update a PolicyPreset, edit the spec portion of a PolicyPreset CR using your preferred method of submitting resource changes with kubectl.
$ kubectl apply -f sample-policy-preset-changed.yaml
policypreset.config.kio.kasten.io/sample-policy-preset configured
Once the change is submitted, Veeam Kasten will re-validate the PolicyPreset and update .status.validation accordingly.
$ kubectl get policypresets.config.kio.kasten.io --namespace kasten-io -w
NAME STATUS AGE
sample-policy-preset Failed 48s
sample-policy-preset Success 50s
Since Veeam Kasten processes API object changes asynchronously, to avoid confusion with a previous PolicyPreset status, it is recommended as convention that the status portion of the PolicyPreset is omitted when submitting changes.
Warning
Every preset's validation status change entails a revalidation
of all the policies that use this preset.
If the preset becomes invalid, the dependent policies also become
invalid, and thus their runs will be skipped.
Changing the preset's type (from being a backup only to backup+export
and vice versa) also entails policies revalidation.
Delete a PolicyPreset
You can delete a PolicyPreset using the following command.
# delete policypreset "sample-policy-preset" for Veeam Kasten installed in "kasten-io"
$ kubectl delete policypresets.config.kio.kasten.io sample-policy-preset --namespace kasten-io
policypreset.config.kio.kasten.io "sample-policy-preset" deleted
Warning
All the policies that use the deleted preset will be automatically marked as invalid.
