K8s Backup Restore Sidecar for Databases

This project adds automatic backup and recovery to databases managed by K8s via sidecar.

The idea is taken from the etcd-backup-restore project.

Probably, it does not make sense to use this project with large databases. However, if it is certain that a database will never grow large, the auto-recovery mechanism can come in very handy.

Supported Databases

Database	Image	Status
postgres	12-alpine	alpha
rethinkdb	2.4.0	alpha

Supported Storage Providers

• GCS Buckets
• Local

How it works

Limitations

• The database is deployed unclustered / standalone
• The database is deployed as a statefulset and the data is backed by a PVC
• No "Point in Time Recovery" (PITR)

Try it out

Requires:

• docker
• kind
• kubectl
• stern

1. Configure your backup provider configuration in deploy/provider-secret.yaml
2. Enable deployment of the provider secret by commenting in the kubectl command in the Makefile's start target
3. Run make start-postgres or start-rethinkdb

Manual restoration

Follow the documentation here in order to manually restore a specific version of your database.
