When you are cloning from a backup, what is the earliest timestamp of the backup is allowed in Autonomous Database?
You can use a running database to create a clone. For databases running onshared Exadata infrastructure, you can also use a backup as the source of your clone. When using a backup, you can select a listed backup to clone from, or create a point-in-time clone. Point-in-time clones contain all data up to a specified timestamp. The specified timestamp must be in the past.
Note When you create a clone from a backup, you must select a backup that is at least two hours old.
