})

Creates a new DB instance from a DB snapshot. The target database is created from the source database restore point with most of the source's original configuration, including the default security group and DB parameter group. By default, the new DB instance is created as a Single-AZ deployment, except when the instance is a SQL Server instance that has an option group associated with mirroring. In this case, the instance becomes a Multi-AZ deployment, not a Single-AZ deployment.

If you want to replace your original DB instance with the new, restored DB instance, then rename your original DB instance before you call the RestoreDBInstanceFromDBSnapshot operation. RDS doesn't allow two DB instances with the same name. After you have renamed your original DB instance with a different identifier, then you can pass the original name of the DB instance as the DBInstanceIdentifier in the call to the RestoreDBInstanceFromDBSnapshot operation. The result is that you replace the original DB instance with the DB instance created from the snapshot.

If you are restoring from a shared manual DB snapshot, the DBSnapshotIdentifier must be the ARN of the shared DB snapshot.

To restore from a DB snapshot with an unsupported engine version, you must first upgrade the engine version of the snapshot. For more information about upgrading a RDS for MySQL DB snapshot engine version, see Upgrading a MySQL DB snapshot engine version. For more information about upgrading a RDS for PostgreSQL DB snapshot engine version, Upgrading a PostgreSQL DB snapshot engine version.

  • First character must be a letter.
  • Can't end with a hyphen or contain two consecutive hyphens.
Example: my-snapshot-id

Parameter additionalStorageVolumes : A list of additional storage volumes to create for the DB instance. You can create up to three additional storage volumes using the names rdsdbdata2, rdsdbdata3, and rdsdbdata4. Additional storage volumes are supported for RDS for Oracle and RDS for SQL Server DB instances only.

Parameter allocatedStorage : The amount of storage (in gibibytes) to allocate initially for the DB instance. Follow the allocation rules specified in CreateDBInstance.

This setting isn't valid for RDS for SQL Server.

If you restore an RDS Custom DB instance, you must disable this parameter.

For more information about automatic minor version upgrades, see Automatically upgrading the minor engine version.

Parameter availabilityZone : The Availability Zone (AZ) where the DB instance will be created.

Default: A random, system-chosen Availability Zone.

Constraint: You can't specify the AvailabilityZone parameter if the DB instance is a Multi-AZ deployment.

Example: us-east-1a

Parameter backupRetentionPeriod : The number of days to retain automated backups. Setting this parameter to a positive number enables backups. Setting this parameter to 0 disables automated backups. This setting doesn't apply to Amazon Aurora DB instances. The retention period for automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

Default: Uses existing setting

Constraints:

  • Must be a value from 0 to 35.
  • Can't be set to 0 if the DB instance is a source to read replicas.
  • Can't be set to 0 for an RDS Custom for Oracle DB instance.

Parameter backupTarget : Specifies where automated backups and manual snapshots are stored for the restored DB instance.

Possible values are local (Dedicated Local Zone), outposts (Amazon Web Services Outposts), and region (Amazon Web Services Region). The default is region.

Parameter copyTagsToSnapshot : Specifies whether to copy all tags from the restored DB instance to snapshots of the DB instance.

In most cases, tags aren't copied by default. However, when you restore a DB instance from a DB snapshot, RDS checks whether you specify new tags. If yes, the new tags are added to the restored DB instance. If there are no new tags, RDS looks for the tags from the source DB instance for the DB snapshot, and then adds those tags to the restored DB instance.

For more information, see Copying tags to DB instance snapshots in the Amazon RDS User Guide.

Parameter customIamInstanceProfile : The instance profile associated with the underlying Amazon EC2 instance of an RDS Custom DB instance. The instance profile must meet the following requirements:

  • The profile must exist in your account.
  • The profile must have an IAM role that Amazon EC2 has permissions to assume.

This setting doesn't apply to RDS Custom.

Parameter enableCustomerOwnedIp : Specifies whether to enable a customer-owned IP address (CoIP) for an RDS on Outposts DB instance.

A CoIP provides local or external connectivity to resources in your Outpost subnets through your on-premises network. For some use cases, a CoIP can provide lower latency for connections to the DB instance from outside of its virtual private cloud (VPC) on your local network.

This setting doesn't apply to RDS Custom.

For more information about RDS on Outposts, see Working with Amazon RDS on Amazon Web Services Outposts in the Amazon RDS User Guide.

For more information about CoIPs, see Customer-owned IP addresses in the Amazon Web Services Outposts User Guide.

Default: open-source-rds-extended-support

Parameter iops : Specifies the amount of provisioned IOPS for the DB instance, expressed in I/O operations per second. If this parameter isn't specified, the IOPS value is taken from the backup. If this parameter is set to 0, the new instance is converted to a non-PIOPS instance. The conversion takes additional time, though your DB instance is available for connections before the conversion starts.

The provisioned IOPS value must follow the requirements for your database engine. For more information, see Amazon RDS Provisioned IOPS storage in the Amazon RDS User Guide.

Constraints: Must be an integer greater than 1000.

  • RDS for MariaDB - general-public-license
  • RDS for Microsoft SQL Server - license-included
  • RDS for MySQL - general-public-license
  • RDS for Oracle - bring-your-own-license | license-included
  • RDS for PostgreSQL - postgresql-license
Default: Same as the source.

Parameter manageMasterUserPassword : Specifies whether to manage the master user password with Amazon Web Services Secrets Manager in the restored DB instance.

For more information, see Password management with Amazon Web Services Secrets Manager in the Amazon RDS User Guide.

Constraints:

  • Applies to RDS for Oracle only.

Parameter masterUserSecretKmsKeyId : The Amazon Web Services KMS key identifier to encrypt a secret that is automatically generated and managed in Amazon Web Services Secrets Manager.

This setting is valid only if the master user password is managed by RDS in Amazon Web Services Secrets Manager for the DB instance.

The Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key. To use a KMS key in a different Amazon Web Services account, specify the key ARN or alias ARN.

If you don't specify MasterUserSecretKmsKeyId, then the aws/secretsmanager KMS key is used to encrypt the secret. If the secret is in a different Amazon Web Services account, then you can't use the aws/secretsmanager KMS key to encrypt the secret, and you must use a customer managed KMS key.

There is a default KMS key for your Amazon Web Services account. Your Amazon Web Services account has a different default KMS key for each Amazon Web Services Region.

Parameter multiAZ : Specifies whether the DB instance is a Multi-AZ deployment.

This setting doesn't apply to RDS Custom.

Constraint: You can't specify the AvailabilityZone parameter if the DB instance is a Multi-AZ deployment.

Parameter networkType : The network type of the DB instance.

Valid Values:

  • IPV4
  • DUAL
The network type is determined by the DBSubnetGroup specified for the DB instance. A DBSubnetGroup can support only the IPv4 protocol or the IPv4 and the IPv6 protocols (DUAL).

For more information, see Working with a DB instance in a VPC in the Amazon RDS User Guide.

Parameter optionGroupName : The name of the option group to be used for the restored DB instance.

Permanent options, such as the TDE option for Oracle Advanced Security TDE, can't be removed from an option group, and that option group can't be removed from a DB instance after it is associated with a DB instance.

This setting doesn't apply to RDS Custom.

Parameter port : The port number on which the database accepts connections.

Default: The same port as the original DB instance

Constraints: Value must be 1150-65535

Parameter preferredBackupWindow : The daily time range during which automated backups are created if automated backups are enabled, as determined by the BackupRetentionPeriod parameter. Changing this parameter doesn't result in an outage and the change is asynchronously applied as soon as possible. The default is a 30-minute window selected at random from an 8-hour block of time for each Amazon Web Services Region. For more information, see Backup window in the Amazon RDS User Guide.

This setting doesn't apply to Amazon Aurora DB instances. The daily time range for creating automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

Constraints:

  • Must be in the format hh24:mi-hh24:mi.
  • Must be in Universal Coordinated Time (UTC).
  • Must not conflict with the preferred maintenance window.
  • Must be at least 30 minutes.

Parameter processorFeatures : The number of CPU cores and the number of threads per core for the DB instance class of the DB instance.

This setting doesn't apply to RDS Custom.

Parameter publiclyAccessible : Specifies whether the DB instance is publicly accessible.

When the DB instance is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB instance's virtual private cloud (VPC). It resolves to the public IP address from outside of the DB instance's VPC. Access to the DB instance is ultimately controlled by the security group it uses. That public access is not permitted if the security group assigned to the DB instance doesn't permit it.

When the DB instance isn't publicly accessible, it is an internal DB instance with a DNS name that resolves to a private IP address.

For more information, see CreateDBInstance.

Parameter storageThroughput : Specifies the storage throughput value for the DB instance.

This setting doesn't apply to RDS Custom or Amazon Aurora.

Parameter storageType : Specifies the storage type to be associated with the DB instance.

If you specify io1, io2, or gp3, you must also include a value for the Iops parameter.

Default: io1 if the Iops parameter is specified, otherwise gp3

Parameter tagSpecifications : Tags to assign to resources associated with the DB instance.

Valid Values:

  • auto-backup - The DB instance's automated backup.

Parameter tdeCredentialArn : The ARN from the key store with which to associate the instance for TDE encryption.

This setting doesn't apply to RDS Custom.

Parameter tdeCredentialPassword : The password for the given ARN from the key store in order to access the device.

This setting doesn't apply to RDS Custom.

Parameter useDefaultProcessorFeatures : Specifies whether the DB instance class of the DB instance uses its default processor features.

This setting doesn't apply to RDS Custom.

Parameter vpcSecurityGroupIds : A list of EC2 VPC security groups to associate with this DB instance.

Default: The default EC2 VPC security group for the DB subnet group's VPC.
