You can create a backup of a volume using Block Volume.
For information to help you decide whether to create a backup or a clone of a boot volume, see Differences Between Block Volume Backups and Clones.
Avoid entering confidential information when assigning descriptions, tags, or friendly names to your cloud resources through the Oracle Cloud Infrastructure Console, API, or CLI.
Required IAM Policy
To use Oracle Cloud Infrastructure, you must be given the required type of access in a policy written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which compartment you should work in.
For administrators: The policy in Let volume admins manage block volumes, backups, and volume groups lets the specified group do everything with block volumes and backups. The policy in Let volume backup admins manage only backups further restricts access to just creating and managing backups.
When users create a backup from a volume or restore a volume from a backup, the volume and backup don't have to be in the same compartment . However, users must have access to both compartments.
If you're new to policies, see Getting Started with Policies and Common Policies. For reference material about writing policies for instances, cloud networks, or other Core Services API resources, see Details for the Core Services.
Using the Console
- Open the navigation menu. Under Core Infrastructure, go to Block Storage and click Block Volumes.
- Click the block volume that you want to create a backup for.
- Click Create Manual Backup.
Enter a name for the backup.
Select the backup type, either incremental or full. See Volume Backup Types for information about backup types.
- Optionally, you can apply tags. If you have permissions to create a resource, 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, see Resource Tags. If you are not sure if you should apply tags, skip this option (you can apply tags later) or ask your administrator.
Click Create Backup.
The backup will be completed once its icon no longer lists it as CREATING in the volume list.
Using the API
To back up a volume, use the following operation:
For information about using the API and signing requests, see REST APIs and Security Credentials. For information about SDKs, see Software Development Kits and Command Line Interface.
