Creating an RDS Custom for Oracle snapshot

RDS Custom for Oracle creates a storage volume snapshot of your DB instance, backing up the entire DB instance and not just individual databases. When your DB instance contains a container database (CDB), the snapshot of the instance includes the root CDB and all PDBs.

When you create an RDS Custom for Oracle snapshot, specify which RDS Custom DB instance to back up. Give your snapshot a name so you can restore from it later.

When you create a snapshot, RDS Custom for Oracle creates an Amazon EBS snapshot for every volume attached to the DB instance. RDS Custom for Oracle uses the EBS snapshot of the root volume to register a new Amazon Machine Image (AMI). To make snapshots easy to associate with a specific DB instance, they're tagged with DBSnapshotIdentifier, DbiResourceId, and VolumeType.

Creating a DB snapshot results in a brief I/O suspension. This suspension can last from a few seconds to a few minutes, depending on the size and class of your DB instance. The snapshot creation time varies with the size of your database. Because the snapshot includes the entire storage volume, the size of files, such as temporary files, also affects snapshot creation time. To learn more about creating snapshots, see Creating a DB snapshot for a Single-AZ DB instance for Amazon RDS.

Create an RDS Custom for Oracle snapshot using the console or the Amazon CLI.

To create an RDS Custom snapshot

  1. Sign in to the Amazon Web Services Management Console and open the Amazon RDS console at https://console.amazonaws.cn/rds/.

  2. In the navigation pane, choose Databases.

  3. In the list of RDS Custom DB instances, choose the instance for which you want to take a snapshot.

  4. For Actions, choose Take snapshot.

    The Take DB snapshot window appears.

  5. For Snapshot name, enter the name of the snapshot.

  6. Choose Take snapshot.

You create a snapshot of an RDS Custom DB instance by using the create-db-snapshot Amazon CLI command.

Specify the following options:

  • --db-instance-identifier – Identifies which RDS Custom DB instance you are going to back up

  • --db-snapshot-identifier – Names your RDS Custom snapshot so you can restore from it later

In this example, you create a DB snapshot called my-custom-snapshot for an RDS Custom DB instance called my-custom-instance.

For Linux, macOS, or Unix:

aws rds create-db-snapshot \
    --db-instance-identifier my-custom-instance \
    --db-snapshot-identifier my-custom-snapshot

For Windows:

aws rds create-db-snapshot ^
    --db-instance-identifier my-custom-instance ^
    --db-snapshot-identifier my-custom-snapshot
