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, or to another cloud provider (in the same or different region) will incur data transfer charges.

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:

    s3://<bucket_name>.s3.amazonaws.com/<directory>

    For example:

    s3://testchbackups.s3.amazonaws.com/backups/

    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:

    https://storage.googleapis.com/<bucket_name>/

  2. Access HMAC key and HMAC secret.

Backup / Restore

Backup / Restore to AWS S3 Bucket​

Take a DB Backup​

Full Backup

BACKUP DATABASE test_backups 
TO S3('https://testchbackups.s3.amazonaws.com/backups/<uuid>', '<key id>', '<key secret>')

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

BACKUP DATABASE test_backups 
TO S3('https://testchbackups.s3.amazonaws.com/backups/<uuid>', '<key id>', '<key secret>') 
SETTINGS base_backup = S3('https://testchbackups.s3.amazonaws.com/backups/<base-backup-uuid>', '<key id>', '<key secret>')

Restore from a backup​

RESTORE DATABASE test_backups 
AS test_backups_restored 
FROM S3('https://testchbackups.s3.amazonaws.com/backups/<uuid>', '<key id>', '<key secret>')

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

Backup / Restore to Azure Blob Storage​

Note

Exporting backups to you own bucket on Azure Blob Storage is not available yet. We will update this page when the feature is available.

Take a DB Backup​

Full Backup

BACKUP DATABASE test_backups 
TO AzureBlobStorage('<AzureBlobStorage endpoint connection string>', '<container>', '<blob>/<uuid>');

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

Incremental Backup

BACKUP DATABASE test_backups 
TO AzureBlobStorage('<AzureBlobStorage endpoint connection string>', '<container>', '<blob>/<uuid>/my_incremental') 
SETTINGS base_backup = AzureBlobStorage('<AzureBlobStorage endpoint connection string>', '<container>', '<blob>/<uuid>')

Restore from a backup​

RESTORE DATABASE test_backups 
AS test_backups_restored_azure 
FROM AzureBlobStorage('<AzureBlobStorage endpoint connection string>', '<container>', '<blob>/<uuid>')

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

BACKUP DATABASE test_backups 
TO S3('https://storage.googleapis.com/<bucket>/<uuid>', <hmac-key>', <hmac-secret>)

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

Incremental Backup

BACKUP DATABASE test_backups 
TO S3('https://storage.googleapis.com/test_gcs_backups/<uuid>/my_incremental', 'key', 'secret')
SETTINGS base_backup = S3('https://storage.googleapis.com/test_gcs_backups/<uuid>', 'key', 'secret')

Restore from a backup​

RESTORE DATABASE test_backups 
AS test_backups_restored_gcs 
FROM S3('https://storage.googleapis.com/test_gcs_backups/<uuid>', 'key', 'secret')
