How to restore a backup

This is a guide on how to perform a basic restore of a local backup of your Charmed MongoDB replica set or sharded cluster.

Prerequisites

A replica set with at least three nodes deployed OR a sharded cluster with at least one shard deployed
- See How To > Scale replicas and shards
Configured settings for S3 storage
- See How To > Configure S3
An existing backup in your S3 storage
- See How To > Create a backup

Determine the application to run backup actions on

The application to pass to juju when running backup and restore actions depends on whether your deployment is a replica set or sharded cluster:

When running Charmed MongoDB as a replica-set, this will be the name of your MongoDB application.

When running Charmed MongoDB as a sharded cluster, this will be the name of your MongoDB application running with the “config-server” role - never the shard applications.

List all backups

To list all backups available, run:

juju run <replica-set name | config-server name>/leader list-backups

This will display available backups similar to the output below:

    backup-id             | backup-type  | backup-status
    ----------------------------------------------------
    YYYY-MM-DDTHH:MM:SSZ  | logical      | finished

Restore a backup

Before restoring a backup, check that your Charmed MongoDB deployment is active and idle with juju status.

To restore a backup from the list, run the restore command using the backup-id:

juju run <replica-set name | config-server name>/leader restore backup-id=YYYY-MM-DDTHH:MM:SSZ

The restore will now be in progress.
