Exclude Specific Items from Backup
It is possible to exclude individual items from being backed up, even if they match the resource/namespace/label selectors defined in the backup spec. To do this, label the item as follows:
kubectl label -n <ITEM_NAMESPACE> <RESOURCE>/<NAME> velero.io/exclude-from-backup=true
Specify Backup Orders of Resources of Specific Kind
To backup resources of specific Kind in a specific order, use option --ordered-resources to specify a mapping Kinds to an ordered list of specific resources of that Kind. Resource names are separated by commas and their names are in format 'namespace/resourcename'. For cluster scope resource, simply use resource name. Key-value pairs in the mapping are separated by semi-colon. Kind name is in plural form.
velero backup create backupName --include-cluster-resources=true --ordered-resources 'pods=ns1/pod1,ns1/pod2;persistentvolumes=pv4,pv8' --include-namespaces=ns1
velero backup create backupName --ordered-resources 'statefulsets=ns1/sts1,ns1/sts0' --include-namespaces=ns1
Schedule a Backup
The schedule operation allows you to create a backup of your data at a specified time, defined by a Cron expression.
velero schedule create NAME --schedule="* * * * *" [flags]
Cron schedules use the following format.
# ┌───────────── minute (0 - 59)
# │ ┌───────────── hour (0 - 23)
# │ │ ┌───────────── day of the month (1 - 31)
# │ │ │ ┌───────────── month (1 - 12)
# │ │ │ │ ┌───────────── day of the week (0 - 6) (Sunday to Saturday;
# │ │ │ │ │ 7 is also Sunday on some systems)
# │ │ │ │ │
# │ │ │ │ │
# * * * * *
For example, the command below creates a backup that runs every day at 3am.
velero schedule create example-schedule --schedule="0 3 * * *"
This command will create the backup, example-schedule, within Velero, but the backup will not be taken until the next scheduled time, 3am. Backups created by a schedule are saved with the name <SCHEDULE NAME>-<TIMESTAMP>, where <TIMESTAMP> is formatted as YYYYMMDDhhmmss. For a full list of available configuration flags use the Velero CLI help command.
velero schedule create --help
Once you create the scheduled backup, you can then trigger it manually using the velero backup command.
velero backup create --from-schedule example-schedule
This command will immediately trigger a new backup based on your template for example-schedule. This will not affect the backup schedule, and another backup will trigger at the scheduled time.
