# Backups

We're using [Ark][1] for backing up Kubernetes config and GKE resources. It is
available as a Git submodule in the `vendor/` folder (incl. the `ark`
executable).

In order to initialize submodules in your local repo, run once:

    git submodule init

Then, to fetch/update the modules, run:

    git submodule update

The Ark service is running on the Sidamo cluster and was set up using the
[official docs' GCP instructions and config files][4].

## Backup location

Cluster configuration (including all live resources) is backed up to [a Google
Cloud Storage container][3].

## Persistent volumes

Persistent volumes are just GCE disks. Thus, with the current config, Ark
creates volume snapshots as native [GCE disk snapshots][2].
