Amazon Relational Database Service (Amazon RDS) now supports increasing the allocated storage size when creating a read replica, when restoring a database from a snapshot, or when restoring a database instance to a point in time. This capability is supported on Amazon RDS for MariaDB, Amazon RDS for MySQL, Amazon RDS for PostgreSQL and Amazon RDS for Oracle databases.

You can specify the new storage size during creation of a read replica or restoration of a database instance. This is especially useful when your primary instances or snapshots are near their maximum allocated storage capacity. In addition, you can make any further storage modifications right after creation of the new database instance with new storage size.

Storage resize capability for DB instance replica and restore creations is available in all AWS Regions, including the AWS GovCloud (US) Regions. Storage resize is also supported by CreateDBInstanceReadReplica, RestoreDBInstanceFromDBSnapshot and RestoreDBInstanceToPointInTime APIs. Learn more about APIs that support storage resize in the Amazon RDS User Guide. To get started, visit the AWS Management Console.
