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. The BACKUP commands listed below are run within the original service. The RESTORE commands are run from a new service where the backup should be restored.

note

Users should be aware that any usage where backups are being exported to a different region in the same cloud provider, or to another cloud provider (in the same or different region) will incur data transfer charges.

note

Backup / Restore into your own bucket for services utilizing TDE is currently not supported.

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.

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

note
  1. For restoring the backup from your own bucket into a new service, you will need to update the trust policy of your backups storage bucket to allow access from the new service.
  2. The Backup / Restore commands need to be run from the database command line. For restore to a new service, you will first need to create the service and then run the command.

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.

Backup / restore to Azure Blob Storage​

Take a DB backup​

Full backup

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

Incremental backup

Restore from a backup​

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

Backup / restore to Google Cloud Storage (GCS)​

Take a DB backup​

Full backup

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

Incremental backup

Granular backups

The BACKUP command also works with granular backups of specific tables. Example AWS commands for backing up a specific table are listed below. GCP and Azure commands are similar to the ones explained above, except that they need to be customized to backup specific tables.
