I have setup 3 data nodes and 3 master nodes, imported all the data that I need. I want to back up all that data and copy it to dev environment. What would be the best way to get this done?

I would like to get data from acgrcdata (0-2) and put it on a different machine but have no idea how to proceed with it

I'd probably use snapshot/restore feature to backup on a shared FS then restore that in the dev env.

@dadoonet How would I combine data from 3 data nodes? I guess a snapshot to shared fs will combine it?
