Backing Up and Restoring an Instance
On Compute Cloud@Customer, supports backing up and restoring instances. The instance backup is created in an Object Storage bucket. From there, you can copy it to another server in your data center for safekeeping. When needed, you can import the backup into any Compute Cloud@Customer Object Storage bucket, and use it to create instances.
Use Cases
- Back up instances and any attached block volumes.
- Store the backups on another server for safekeeping.
- Restore a faulty instance and any attached block volumes.
- Use the backup to create matching instances.
- Use the backup and restore feature to migrate instances to another tenancy, or to another Compute Cloud@Customer.
The restored instance has some of the same characteristics as the source instance. For example:
- The type and version of the OS.
- The OS configuration matches the OS configuration of the source instance. This includes things like OS user accounts, installed applications, and so on.
- The type of storage, high-performance or balanced-performance, matches the source instance.
- All the software on the block volumes is available after you attached the block volumes to the restored instance.
Some aspects of the restored instance differ from the source instance, such as:
- The restored instance and associated components, like boot and block volumes have unique OCIDs that don't match the source instance.
- The source instance user account SSH keys aren't included in the restored instance.
- While creating the restored instance, you can configure the instance in a different compartment, with a different name, shape, subnet, and all the other attributes that you configure during the launch.
