AWS EBS Crash consistent snapshots

[fcharlier]

Hi !

I'm evaluating barman-cloud-backup for use on our small database and I was wondering about the following:

AWS has an API call which allows to do crash-consistent snapshots on an instance: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/ec2/client/create_snapshots.html

This allows in one call to have a snapshot created at the same time for all volumes attached to an instance (some volumes can be excluded if desired).

Would this be an option to use instead of looping over all volumes and creating a separate snapshot for each one (as currently implemented) ?
