Export Backups to your Own Cloud Account

Enterprise plan feature

This feature is available in the Enterprise plan. To upgrade, visit the Plans page in the cloud console.

ClickHouse Cloud supports taking backups to your own cloud service provider (CSP) account (AWS S3, Google Cloud Storage, or Azure Blob Storage). For details of how ClickHouse Cloud backups work, including "full" vs. "incremental" backups, see the backups docs.

Here we show examples of how to take full and incremental backups to AWS, GCP, Azure object storage as well as how to restore from the backups.

Note

Users should be aware that any usage where backups are being exported to a different region in the same cloud provider, will incur data transfer charges. Currently we do not support cross cloud backups.

Requirements​

You will need the following details to export/restore backups to your own CSP storage bucket.

AWS​

  1. AWS S3 endpoint, in the format:

    For example:

    Where:

    • testchbackups is the name of the S3 bucket to export backups to.
    • backups is an optional subdirectory.

  2. AWS access key and secret. AWS role based authentication is also supported and can be used in place of AWS access key and secret.

Note

In order to use role based authentication, please follow the Secure s3 setup. In addition, you will need to add s3:PutObject, and s3:DeleteObject permissions to the IAM policy decribed here.

Azure​

  1. Azure storage connection string.
  2. Azure container name in the storage account.
  3. Azure Blob within the container.

Google Cloud Storage (GCS)​

  1. GCS endpoint, in the format:

  2. Access HMAC key and HMAC secret.

Backup / Restore

Backup / Restore to AWS S3 Bucket​

Take a DB Backup​

Full Backup

Where uuid is a unique identifier, used to differentiate a set of backups.

Note

You will need to use a different UUID for each new backup in this subdirectory, otherwise you will get a BACKUP_ALREADY_EXISTS error. For example, if you are taking daily backups, you will need to use a new UUID each day.

Incremental Backup

Restore from a backup​

See: Configuring BACKUP/RESTORE to use an S3 Endpoint for more details.
