Create/update an automated snapshots config

This endpoint requires sudo capability.

This endpoint creates or updates a named configuration. Each configuration has an interval controlling how often snapshots are taken, a destination where the snapshots are written, as well as a retention policy governing when older snapshots get deleted.

Note that for cloud storage types, you can either provide credentials explicitly using the parameters below, or for GCP and AWS you can omit them and rely on the other mechanisms the cloud provider's SDK allows for authenticating, e.g. environment variables or files on disk in predefined locations.

Parameters

• name (string: <required>) – Name of the configuration to modify.

• interval (integer or string: <required>) - Time between snapshots. This can be either an integer number of seconds, or a Go duration format string (e.g. 24h)

• retain (integer: 1) - How many snapshots are to be kept; when writing a snapshot, if there are more snapshots already stored than this number, the oldest ones will be deleted.

• path_prefix (string: <required>) - For storage_type=local, the directory to write the snapshots in. For cloud storage types, the bucket prefix to use. Types azure-blob and google-gcs require a trailing / (slash). Types local and aws-s3 the trailing / is optional.

• file_prefix (string: "vault-snapshot") - Within the directory or bucket prefix given by path_prefix, the file or object name of snapshot files will start with this string.

• storage_type (string: <required>) - One of "local", "azure-blob", "aws-s3", or "google-gcs". The remaining parameters described below are all specific to the selected storage_type and prefixed accordingly.

storage_type=local

• local_max_space (integer: <required>) - For storage_type=local, the maximum space, in bytes, to use for snapshots. Snapshot attempts will fail if there is not enough space left in this allowance.

storage_type=aws-s3

• aws_s3_bucket (string: <required>) - S3 bucket to write snapshots to.

• aws_s3_region (string: <required>) - AWS region bucket is in.

• aws_access_key_id (string) - AWS access key ID.

• aws_secret_access_key (string) - AWS secret access key.

• aws_session_token (string) - AWS session token.

• aws_s3_endpoint (string) - AWS endpoint. This is typically only set when using a non-AWS S3 implementation like Minio.

• aws_s3_disable_tls (boolean) - Disable TLS for the S3 endpoint. This should only be used for testing purposes, typically in conjunction with aws_s3_endpoint.

• aws_s3_force_path_style (boolean) - Use the endpoint/bucket URL style instead of bucket.endpoint. May be needed when setting aws_s3_endpoint.

• aws_s3_enable_kms (boolean) - Use KMS to encrypt bucket contents.

• aws_s3_server_side_encryption (boolean) - Use AES256 to encrypt bucket contents. Cannot use with aws_s3_enable_kms parameter.

• aws_s3_kms_key (string) - Use named KMS key, when aws_s3_enable_kms=true

storage_type=google-gcs

• google_gcs_bucket (string: <required>) GCS bucket to write snapshots to.

• google_service_account_key (string) - Google service account key in JSON format. Depending on how the API is invoked, this may be need to be JSON-escaped, e.g. for newlines and double quotes. The raw value looks like this:

{
  "type": "service_account",
  "project_id": "project-id",
  "private_key_id": "key-id",
  "private_key": "-----BEGIN RSA PRIVATE KEY-----\nMIIEpQ ... /WZs=\n-----END RSA PRIVATE KEY-----\n",
  "client_email": "service-account-email",
  "client_id": "client-id",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://accounts.google.com/o/oauth2/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/service-account-email"
}

• google_endpoint (string) - GCS endpoint. This is typically only set when using a non-Google GCS implementation like fake-gcs-server.

• google_disable_tls (boolean) - Disable TLS for the GCS endpoint. This should only be used for testing purposes, typically in conjunction with google_endpoint.

storage_type=azure-blob

• azure_container_name (string: <required>) - Azure container name to write snapshots to.

• azure_account_name (string) - Azure account name.

• azure_account_key (string) - Azure account key.

• azure_blob_environment (string) - Azure blob environment.

• azure_endpoint (string) - Azure blob storage endpoint. This is typically only set when using a non-Azure implementation like Azurite.
