Let’s continue our journey of deploying the MySQL Database System
on OCI with Terraform.
This time we will see how we can use a backup (see [1] and [2]) as a source (initial data) for a new

data of the db system.
Let’s deploy a new MySQL Database Instance using a manual backup we made earlier:
We can also find the backup’s ocid using the oci cli
command:
$ oci mysql backup list …
