How to backup mail, contacts and gsuite/gapps calendar?

Question

Google

There is a task to take out mail on paid gmail, it is gsuite.
The question arises - how to backup everything? Everything is clear with your local mail server, but what about gsuite.
The Internet is full of proposals to carry out cloud-to-cloud backups, which is unacceptable.
I would like a solution that will allow us to drag scheduled backups to our servers, search and selectively restore data, something like Veeam Backup for office 365.
What worthy products can I look at?
P.S. gvault, cloud2cloud solutions are not suitable.
