A robust backup strategy is fundamental to keeping data safe.
By default, Elest.io automates a 3-2-1 backup strategy for all new services.
3 copies of your data exist at all times.
2 are kept in geographically distinct data centers in your selected region.
1 backup is kept on-site for fast restoring.
Each backup type has different retention periods and characteristics.
Local backups are useful if you need to take a quick backup of a small dataset locally and want to download the backup to your computer, or just be able to restore it later quickly.
Local backups only contain the software's data volume, not the OS or software itself.
From the service dashboard, click on the Backups tab, then click on Manual Local Backups.
From there you can make new manual backups, list existing backups, download, restore or delete previous local backups.
You are responsible for deleting manual backups to regain disk space. Elest.io will not automatically delete them.
Manual backups use the available disk space of your service.
Remote backups are sent to another datacenter in the same continent that your service (Ashburn USA for the US, Germany for EU zone and rest of the world). We use Borg Backups to do incremental backups with deduplication. It's very fast and efficient. This kind of backup includes only the data, not the software itself.
From the Dashboard, click on the Backups tab, then click on Automated Remote Backups.
From there you can make new manual backups, list existing backups or restore a backup.
Retention periods depend on your support plan: 7 days on Standard, 14 days on Premium and 30 days on Enterprise.
VM snapshots are made using the provider's snapshot API and are stored in the same region where you have your service.
It is only available under Support Plans Levels 2 and 3.
It's a full snapshot of the VM, meaning it contains everything: OS, Apps, data, etc.
To make a snapshot
From the Dashboard:
- Click on the Backups tab
- Click on Automated Snapshots
From there you can take new a manual snapshot, list existing snapshots or restore a snapshot.
Retention periods depend on your support plan: 2 snapshots on Level 2, and 4 snapshots on Level 3.
Restoring from a snapshot will overwrite the whole VM with the selected snapshot.
External backups are stored in your S3 bucket, so you own your backups directly. Elestio's external backup service is compatible with AWS S3 and any S3-compatible provider.
To enable external backups from the service dashboard click on the Backups tab, then click on Automated External Backups.
You will have to provide your S3 details. (endpoint, bucket name, API key, secret key)
Before entering the bucket
You can click on the "Verify Config" button to validate your settings.
Once activated, you will be able to click on Settings to configure the backups schedule. You can also take an external backup at any time with the "Take a backup" button.
If you click on Settings, you can configure the backups schedule and a number of backups to retain.
If you don't have access to an AWS S3 bucket or an S3 bucket from another provider, you can deploy Minio to get your own S3 Bucket
