Create a backup
This is a guide on how to create and list backups of a Charmed MongoDB replica set or sharded cluster using Amazon S3 storage.
Prerequisites
- Access to Amazon S3 storage.
- Configured settings for S3 storage
- A replica set with at least three nodes deployed OR a sharded cluster with at least one shard deployed
Summary
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.
Create a backup
Before creating a backup, check that your Charmed MongoDB deployment is
activeandidlewithjuju status.
To create a backup, use the create-backup command on the leader unit:
juju run <replica-set name | config-server name>/leader create-backup
List all backups
To list all available, failed, and in-progress backups, use the list-backup command on the leader unit:
juju run <replica-set name | config-server name>/leader list-backups
