Backup data is stored in two regions on same continent, except for austriala where data is stored also in Asia.
I need to export backup, can I do this?
No
When talking a backup of the database, will performance be affected?
No for Gen2 and Yes for Gen1
I need to increase the read performance of CloudSQL, what are my options?
Create read replicas.
I need to increase the read performance of CloudSQL, what are my options?
Create read replicas, I can do this in any of the zones in the region.
I need to ensure high availability for Cloud=SQL MySQL, what options do I have?
You can create a fail-over instance of the data base.
What is CloudSQL proxy?
It enables you to connect form your application to CloudSQL with out exposing a public IP.
How can make a copy of ClodSQL quickly?
Use DB cloning.

Yes, this is an option in the web console.
Can I have two fail-over replicas of CloudSQL?
No, only a single replica is allowed.
When fail-over occurs of the CloudSQL database, will I have to use a new IP to connect with the CloudSQL?
No, the IP is changed to the failed over instance.
I have an on-prem MySQL database and I want to migrate it to cloud, what options do I have?
