Backups in ArangoGraph

How to create backups

To backup data in ArangoGraph for an ArangoDB installation, navigate to the Backups section of your deployment created previously.

There are two ways to create backups. Create periodic backups using a Backup policy, or create a backup manually. Both ways allow you to create backups in multiple regions as well.

Periodic backups

Periodic backups are created at a given schedule. To see when the new backup is due, observe the schedule section.

When a new deployment is created, a default Backup policy is created for it as well. This policy creates backups every two hours. To edit this policy (or any policy), highlight it in the row above and hit the pencil icon.

These backups are not automatically uploaded. To enable this, use the Upload backup to storage option and choose a retention period that specifies how long backups are retained after creation.

If the Upload backup to storage option is enabled for a backup policy, you can then create backups in different regions than the default one. The regions where the default backup is copied are shown in the Additional regions column in the Policies section.

Manual backups

It’s also possible to create a backup on demand. To do this, click Back up now.

If you want to manually copy a backup to a different region than the default one, first ensure that the Upload backup to storage option is enabled. Then, highlight the backup row and use the Copy backup to a different region button from the Actions column.

The source backup ID from which the copy is created is displayed in the Copied from Backup column.

Uploading backups

By default, a backup is not uploaded to the cloud, instead it remains on the servers of the deployment. To make a backup that is resilient against server (disk) failures, upload the backup to cloud storage.

When the Upload backup to cloud storage option is enabled, the backup is preserved for a long time and does not occupy any disk space on the servers. This also allows copying the backup to different regions and it can be configured in the Multiple region backup section.

Uploaded backups are required for cloning.

Best practices for uploading backups

When utilizing the Upload backup to cloud storage feature, a recommended approach is to implement a backup strategy that balances granularity and storage efficiency.

One effective strategy involves creating a combination of backup intervals and retention periods. For instance, consider the following example:

1. Perform a backup every 4 hours with a retention period of 24 hours. This provides frequent snapshots of your data, allowing you to recover recent changes.
2. Perform a backup every day with a retention period of a week. Daily backups offer a broader time range for recovery, enabling you to restore data from any point within the past week.
3. Perform a backup every week with a retention period of a month. Weekly backups allow you to recover from more extensive data.
4. Perform a backup every month with a retention period of a year. Monthly backups provide a long-term perspective, enabling you to restore data from any month within the past year.

This backup strategy offers good granularity, providing multiple recovery options for different timeframes. By implementing this approach, you have a total number of backups that is considerable lower in comparison to other alternatives such as having hourly backups with a retention period of a year.

Multi-region backups

Using the multi-region backup feature, you can store backups in multiple regions simultaneously either manually or automatically as part of a Backup policy. If a backup created in one region goes down, it is still available in other regions, significantly improving reliability.

Multiple region backup is only available when the Upload backup to cloud storage option is enabled.

How to restore backups

To restore a database from a backup, highlight the desired backup and click the restore icon.

How to clone deployments using backups

1. Highlight the backup you wish to clone from and hit Clone backup to new deployment.

   

2. Choose whether the clone should be created in the same region as the backup or in a different region.

   

3. The view should navigate to the new deployment being bootstrapped.

   

This feature is also available through oasisctl.
