Prerequisite Configuration Checklist for Recovery Service
This checklist describes the prerequisite tasks that you must complete before you can use Recovery Service as the backup destination for the databases in your tenancy.
Note:
Operational backups to two different backup destinations may create data loss scenarios. Therefore, before you enable automatic backups to Recovery Service, you must disable manual backup scripts and processes to other storage destinations.Table 2-1 Prerequisite Task Checklist to Use Recovery Service as the Automatic Backup Destination

Review Limits for Recovery Service
A service limit is the quota or allowance set on a resource. Use the console to verify that your tenancy's Recovery Service resource limits are adequate to meet your database backup demands.
Autonomous Recovery Service has maximum limits for the number of protected databases and the backup storage space utilization. The limits apply to each region.

Configuring Network Resources for Recovery Service
Use an existing IP4-only subnet in the database VCN for Recovery Service operations. Define security rules to control the backup traffic between your database and Recovery Service. Finally, register the private subnet as a Recovery Service subnet.
- About Using a Private Subnet for Recovery Service
Recovery Service uses a private subnet inside a virtual cloud network (VCN) where your database resides. The private subnet defines the network path for backups between your database and Recovery Service. - Review Networking Service Permissions to Configure a Subnet
Ensure that you have these Networking Service permissions required to create a subnet in the database VCN and to assign security rules for Recovery Service. - Review Subnet Size Requirements and Security Rules for Recovery Service Subnet

About Using a Private Subnet for Recovery Service
Recovery Service uses a private subnet inside a virtual cloud network (VCN) where your database resides. The private subnet defines the network path for backups between your database and Recovery Service.
Oracle recommends that your database VCN must have a single private subnet dedicated for backups to Recovery Service. Your Oracle Cloud database can reside in the same private subnet used by Recovery Service, or in a different subnet within the same VCN.
You can either create a private subnet or use a preexisting subnet in your database VCN. Oracle recommends that you use a subnet size of /24 (256 IP addresses).
Note:
Select an IPv4-only subnet for Recovery Service in your database VCN. Do not select an IPv6-enabled subnet as Recovery Service does not support using an IPv6-enabled subnet. See Creating a Subnet to learn more.- Security Lists
A security list allows you to add security rules at the subnet level. In your database VCN, select the security list that is used for the Recovery Service subnet, and add the ingress rules to allow destination ports 8005 and 2484.
- Network Security Groups (NSG)Network security groups (NSG) enable granular control over security rules that apply to individual VNICs in a VCN. Recovery Service supports these options to configure security rules using NSGs:
- To implement network isolation, create one NSG for the database VNIC (add egress rules to allow ports 2484 and 8005) and a separate NSG for Recovery Service (add ingress rules to allow ports 2484 and 8005).
- Create and use a single NSG (with egress and ingress rules) for the database VNIC and Recovery Service.
Note:
If you have configured a security list and an NSG within your database VCN, then the rules defined in the NSGs takes precedence over the rules defined in a security list.See Comparison of Security Lists and Network Security Groups to learn more.
After you create a private subnet in the database VCN, assign the security rules and then register the subnet as a Recovery Service subnet in Recovery Service. If you have created NSGs to implement security rules, then you must also ensure to associate the Recovery Service NSG with the Recovery Service subnet.
Note:
Oracle recommends using a private subnet for your backups. However, it is possible to use a public subnet.Parent topic: Configuring Network Resources for Recovery Service
Review Networking Service Permissions to Configure a Subnet
Ensure that you have these Networking Service permissions required to create a subnet in the database VCN and to assign security rules for Recovery Service.

Alternatively, you can create a policy that allows a specified group with broader access to networking components.
For example, use this policy to allow a NetworkAdmin
group to manage all networks in any compartment in a tenancy.

Review Subnet Size Requirements and Security Rules for Recovery Service Subnet
The security rules are necessary to allow backup traffic between a database and Recovery Service.
Note:
Select an IPv4-only subnet for Recovery Service in your database VCN. Do not select an IPv6-enabled subnet as Recovery Service does not support using an IPv6-enabled subnet. See Creating a Subnet to learn more.Table 2-9 Subnet size requirements and ingress rules for a private subnet used by Recovery Service
Item | Requirements |
---|---|
Recommended subnet size |
/24 (256 IP addresses) |
General ingress rule 1: Allow HTTPS traffic from Anywhere |
This rule allows backup traffic from your Oracle Cloud Infrastructure Database to Recovery Service.
|
General ingress rule 2: Allows SQLNet Traffic from Anywhere |
This rule allows recovery catalog connections and real-time data protection from your Oracle Cloud Infrastructure Database to Recovery Service.
|
Note:
If you use network security groups (NSG) to implement security rules or if your database VCN restricts network traffic between subnets, then ensure to add an egress rule for ports 2484 and 8005 from the database NSG or subnet to the Recovery Service NSG or subnet that you create.Parent topic: Configuring Network Resources for Recovery Service

After you have created a private subnet for Recovery Service in your database VCN, use this procedure to register the subnet in Recovery Service.
Note:
Select an IPv4-only subnet for Recovery Service in your database VCN. Do not select an IPv6-enabled subnet as Recovery Service does not support using an IPv6-enabled subnet.You can replace a subnet or add more subnets to support the required number of private endpoints.
