Velero backups can quickly grow in size if they're not maintained correctly. Let's perform the following steps to remove an existing backup resource and clean up scheduled backups:

1. Delete the existing backup named myapp-backup:

$ velero backup delete myapp-backup

2. Delete all existing backups:

$ velero backup delete --all

3. Delete the scheduled backup job named myapp-daily:

$ velero schedule delete myapp-daily
