14.14 Cloud Storage Options

These options are for using cloud storage for single-file operations. See Section 4.3.5.3, “Backing Up to Cloud Storage”, and Section 5.2.6, “Restoring a Backup from Cloud Storage to a MySQL Server”, for more information and instructions on using cloud storage with MySQL Enterprise Backup.

• --cloud-service=SERVICE

  Cloud service for data backup or restoration. Currently, there are two types of cloud storage services supported by mysqlbackup, represented by the following values for the options:

  • openstack: OpenStack Swift or compatible object storage services (for example, Oracle Cloud Infrastructure Object Storage and Oracle Cloud Infrastructure Object Storage Classic).

  • s3: Amazon Simple Storage Service (S3).

    Note

    Due to some issues, Amazon S3 is currently not supported by MySQL Enterprise Backup 3.12.

• --cloud-trace

  Print trace information for cloud operations. It works independently of --trace, which specifies the trace level for the non-cloud operations of mysqlbackup. Any non-zero value for the option enables the trace function.

  Default value is “0.”

• --cloud-proxy=proxy-url:port

  Proxy address and port number for overriding the environment's default proxy settings for accessing a cloud storage service.

  Note

  The list-image operation can be performed on a cloud backup only if the cloud proxy supports HTTP range headers.

• --cloud-ca-info=PATH

  (For release 3.12.3 and later) Absolute path to the CA bundle file for host authentication for SSL connections. When the option is specified, the usage of the CA bundle file is preferred over the usage of individual .pem files for host authentication. .

• --cloud-ca-path=PATH

  (For release 3.12.3 and later) CA certificate directory, in addition to the system's default folder.

• Options used only for OpenStack Swift (using them when the argument for --cloud-service is anything other than openstack will cause mysqlbackup to throw an error):

  • --cloud-container=SWIFT_CONTAINER

    The Swift container for the backup image. For Oracle Cloud Infrastructure (OCI) Object Storage, this is the object storage bucket.

  • --cloud-object=SWIFT_OBJECT

    The Swift object for the backup image. Note that names of objects within the same container (or bucket, for OCI Object Storage) have to be unique.

  • --cloud-user-id=SWIFT_USER_ID

    User ID for accessing Swift. The user credentials are authenticated using the Swift TempAuth identity system when the --cloud-tempauth-url option is used and by the OpenStack Keystone identity service when the --cloud-identity-url option is used.

  • --cloud-password=SWIFT_PASSWORD

    Password for accessing Swift for the user specified by the --cloud-user-id option. The user credentials are authenticated using the Swift TempAuth identity system when the --cloud-tempauth-url option is used and by the OpenStack Keystone identity service when the --cloud-identity-url option is used.

  • --cloud-tempauth-url=SWIFT_TEMPAUTH-URL

    The TempAuth URL for authenticating user credentials. Either this option or --cloud-identity-url (but not both) should be used when accessing a Swift service.

  • --cloud-identity-url=SWIFT_KEYSTONE-URL

    The URL of the Keystone identity service, when it is used for authenticating user credentials. Either this option or --cloud-tempauth-url (but not both) should be used when accessing a Swift service.

  • --cloud-tenant=SWIFT_KEYSTONE-TENANT

    The Keystone tenant for the user specified by --cloud-user-id, when the Keystone identity service is used for authenticating user credentials.

  • --cloud-region=SWIFT_KEYSTONE-REGION

    The Keystone region for the user specified by --cloud-user-id, when the Keystone identity service is used for authenticating user credentials.

• Options used only for Amazon S3 (using them when the argument for --cloud-service is anything other than s3 will cause mysqlbackup to throw an error):

  • --cloud-bucket=S3_BUCKET

    The storage bucket on Amazon S3 for the backup image.

    In order to perform cloud backups and restores with the bucket, the user identified by the --cloud-access-key-id option must have at least the following permissions on the bucket:

    • s3:ListBucket: For listing information on items in the bucket.

    • s3:ListBucketMultipartUploads: For listing multipart uploads in progress to the bucket.

    • s3:GetObject: For retrieving objects from the bucket.

    • s3:PutObject: For adding objects to the bucket.

  • --cloud-object-key=S3_OBJECT_KEY

    The Amazon S3 object key for the backup image.

  • --cloud-access-key-id=S3_KEY-ID

    AWS access key ID for logging onto Amazon S3.

  • --cloud-secret-access-key=S3_ACCESS-KEY

    AWS secret access key for the AWS access key id specified with --cloud-access-key-id.

  • --cloud-aws-region=S3_REGION

    Region for Amazon Web Services that mysqlbackup accesses for S3.
