Restoring data from old mariadb columnstore to new one without disrupting the old one

From an old MariaDB columnstore, a live and running one, which cannot be stopped for a long time and having a database of 400 GB, is it possible to restore the database to another server, a new one? The tricky situation is that the data in old one is constantly changing too.

How can we restore the data from the old one?

I was thinking of enabling the binary log and taking incremental backup. Does it work with MariaDB columnstore?
