title: Backing up Rancher Installed on a K3s Kubernetes Cluster
weight: 1
---
---
When Rancher is installed on a high-availability Kubernetes cluster, we recommend using an external database to store the cluster data.
The database administrator will need to back up the external database, or restore it from a snapshot or dump.
We recommend configuring the database to take recurring snapshots.
### Creating Snapshots and Restoring Databases from Snapshots
For details on taking database snapshots and restoring your database from them, refer to the official database documentation:
- [Official MySQL documentation](https://dev.mysql.com/doc/refman/8.0/en/replication-snapshot-method.html)
- [Official PostgreSQL documentation](https://www.postgresql.org/docs/8.3/backup-dump.html)
- [Official etcd documentation](https://github.com/etcd-io/etcd/blob/master/Documentation/op-guide/recovery.md)
