Learn cluster backup with Velero.
Velero
Velero is a tool that backs up Kubernetes objects and volume data to object storage (S3, GCS, Azure Blob). It doesn't need etcd access; it works through the API, so it is used in managed clusters too. It backs up by namespace or label selection and takes volumes as disk snapshots or at file level (Kopia):
velero install --provider aws --plugins velero/velero-plugin-for-aws:v1.10.0 \
--bucket yedek-tr --backup-location-config region=eu-central-1 \
--secret-file ./velero-kimlik --use-node-agent
velero backup create magaza-elle --include-namespaces magaza
velero backup describe magaza-elle --detailsScheduled backups
velero schedule create defines regular backups with a cron expression; --ttl is the retention period:
$ velero schedule create gece --schedule="0 2 * * *" --include-namespaces magaza --ttl 720h
Schedule "gece" created successfully.
$ velero schedule get
NAME STATUS CREATED SCHEDULE BACKUP TTL
gece Enabled 2026-11-03 10:20:00 +0300 +03 0 2 * * * 720h0m0sPractice Nightly backup
Write three commands: create a backup named magaza-elle for the magaza namespace; create a schedule named gece that backs up magaza every night at 02:00 ("0 2 * * *") and keeps it for 720 hours; list the schedules.

1 What is Velero's advantage over an etcd snapshot?
- It only works on kubeadm
- It backs up selectively at namespace level and also takes volume data Correct answer
