Camunda 8 Backup

Hi Camunda Team, I have a couple of questions regarding the Backup:

https://docs.camunda.io/docs/components/concepts/backups/Actually they were asked by a client, and I wanted to double check with you:

  1. Can I customize backup configurations, such as specifying which components or datasets to include in the backup, or is the backup process standardized for all customers (backing up the whole)?
  2. In the event of a disaster or data loss, what is the process for restoring from backups?
  3. How quickly can backups be restored, and what steps do I need to take to initiate the restoration process?
  4. Are there any additional costs associated with using the backup feature, such as storage fees or charges for backup operations beyond certain thresholds?

I would be very grateful if you can reply to those questions
Cheers
Gerardo
