You restore your backup from within an existing Cloud instance. That may be your current instance or another one.

The article I linked in my previous answer above describes how to start the restore:

Restoring the backup will overwrite all data in that instance.

how do you access the backlog? DOes it create a new instance?

[Daniel Ebers]

Backlog in terms of Kanban/Scrum Boards are a whole different topic.
Please be so kind and open a new thread here in Community if the question is still current.
Please also explain what is meant by "does it create a new instance" in particular.

If the question should be about import/export of Jira Cloud please be so kind and rephrase your question so the Community is able to understand and able to help better.
