Creating Database Backup Destinations for Oracle Exadata Database Service on Cloud@Customer

Oracle Exadata Database Service on Cloud@Customer provides a backup facility, which you can configure individually on each database.

To store database backups on a Recovery Appliance or on a network file storage (NFS) location that you manage, then you must first create a backup destination.

About Managing Backup Destinations for Oracle Exadata Database Service on Cloud@Customer

For backups, you can either use the Oracle Exadata Database Service on Cloud@Customer backup facility, or you can configure a backup location on a location you manage.

Oracle Exadata Database Service on Cloud@Customer provides a backup facility, which you can configure individually on each database.

See: Managing Databases on Exadata Cloud@Customer and Managing Database Backup and Recovery on Exadata Cloud@Customer.

If you want to store backups on a Recovery Appliance, or on a network file storage (NFS) location that you manage, then you must first create a backup destination. Each backup destination defines the properties that are required to connect to the Recovery Appliance or NFS location, and each backup destination must be accessible in your data center from the VM cluster nodes.

The Oracle Exadata Database Service on Cloud@Customer backup facility can also store backups on Oracle Cloud Infrastructure object storage, or on local Exadata storage on your Oracle Exadata Database Service on Cloud@Customer system. However, you do not need to create a backup destination for any of these other locations. Instead, applicable options for backup to cloud object storage or local Exadata storage are available directly when you create a database.

Note

Avoid entering confidential information when assigning descriptions, tags, or friendly names to your cloud resources through the Oracle Cloud Infrastructure Console, API, or CLI.

Prerequisites for Backup Destinations for Oracle Exadata Database Service on Cloud@Customer

To configure backup destinations on a Zero Data Loss Recovery Appliance location, or an NFS backup location, review the prerequisites.

  • For a Zero Data Loss Recovery Appliance backup destination:
    • The appliance must be configured with a virtual private catalog (VPC) user, which is used for taking the backups.
    • The appliance must be configured with the unique database name of the database being backed up, and a mapping to the VPC user.
    • The appliance must be accessible from the Oracle Exadata Database Service on Cloud@Customer system using the Oracle Net Services connection string, which is provided by the Zero Data Loss Recovery Appliance administrator.
  • For an NFS backup destination:
    • Oracle Exadata Database Service on Cloud@Customer non-autonomous databases:
      • You must mount the NFS server location to a local mount point directory on each node in the VM cluster.
      • The local mount point directory and the NFS server must be identical across all nodes in the cluster.
      • You must ensure that the NFS mount is maintained continuously on all of the VM cluster nodes.
      • The NFS-mounted file system must be readable and writable by the oracle operating system user on all of the VM cluster nodes.
    • Autonomous Database on Cloud@Customer:
      Note

      Oracle Autonomous Database on Exadata Cloud@Customer supports NFS versions 3 and 4. Mounts with both versions enabled, however, default to version 4.
      • To ensure that the Autonomous VM cluster can access the NFS server over the (preferred) Backup Network, enter valid Backup Network IP addresses while configuring the VM Cluster Network.

        If the backup destination is not accessible over the backup network but accessible over the client network, the backup traffic will be routed over the client network.

      • The NFS-mounted file system must be readable and writable by the oracle operating system user on all of the VM cluster nodes.
      • If permissions are being controlled at the user level, then the uid:gid of the oracle user for the Autonomous VM cluster is 1001:1001.
      • For NFSv4 servers that restrict port range, you must use the insecure option to enable clients other than an Administrator user to connect to the NFS server.

Using the Console for Backup Destinations for Oracle Exadata Database Service on Cloud@Customer

Learn how to use the console to create, edit, move, and terminate a backup destination for your infrastructure for Oracle Exadata Database Service on Cloud@Customer.

Using the Console to Create a Backup Destination

To create a backup destination, be prepared to provide values for the backup destination configuration.

  1. Open the navigation menu. Under Oracle Database, click Exadata Database Service on Cloud@Customer.
  2. Choose the Region that contains your Exadata infrastructure.
  3. Click Backup Destinations.
  4. Click Create Backup Destination.
  5. Provide the requested information in the Create Backup Destination page:
    1. Choose a compartment.

      From the list of available compartments, choose the compartment that you want to contain the backup destination.

    2. Name your backup destination.

      Specify a user-friendly name that you can use to identify the backup destination. The name doesn't need to be unique because an Oracle Cloud Identifier (OCID) uniquely identifies the backup destination.

    3. Choose either a Zero Data Loss Recovery Appliance or a network file system (NFS) backup destination.
      Note

      You can also set OCI Object Store as a backup destination. However, you cannot set it from this screen. You can configure OCI Object Store as a backup destination when creating a database. For more information, see Backup Destination Type in Using the Console to Create a Database.

      Select Recovery Appliance or Network Storage (NFS).

      • If you select Recovery Appliance, then you must also specify the following for Zero Data Loss Recovery Appliance:
        • Provide the Recovery Appliance connection string: Specify the Oracle Net Services connection string that connects to the appliance. This information is typically provided by the Zero Data Loss Recovery Appliance administrator.
          Note

          ADB customers must ensure to provide the connection string that connects to the recovery appliance in an Oracle "easy connect" string format, as shown below:
          host:port/service name

          Where host is the SCAN hostname of the Zero Data Loss Recovery Appliance.

        • Provide the Virtual Private Catalog (VPC) Users: Provide a VPC user name for connecting to the Zero Data Loss Recovery Appliance. You can specify multiple VPC user names in case you want to use the appliance as a backup destination for multiple databases. This information is typically provided by the Zero Data Loss Recovery Appliance administrator.
      • If you select Network Storage (NFS), then you must also specify the following:
        • Self-mount for non-autonomous databases:

          Provide the local NFS mount point path: Specify the local directory path on each VM cluster node where the NFS server location is mounted. The local directory path and the NFS server location must each be the same across all of the VM cluster nodes.
        • Auto-mount for Autonomous Databases:

          Use this destination for Autonomous Databases:
          • NFS server: Specify the IP address of the NFS server. Optionally, you can specify up to four IP addresses. These are just extra paths to the same NFS server. Note that Oracle supports only one NFS device for backups.
          • NFS export share: Specify the directory path where the exported file system is mounted.
    4. Configure Advanced Options.
      • Tags: (Optional) You can choose to apply tags. If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, refer to information about resource tags. If you are not sure if you should apply tags, then skip this option (you can apply tags later), or ask your administrator.
