I want to use the `max_snapshot_bytes_per_sec` to throttle the speed of the Elastic search snapshot. Checked the documentation, could not find an example on how to specify the limit.

Which one of the below value is correct to limit the speed to 10mb.

{"type":"fs","settings":{"location":"/var/ESBackup/snapshot\_test","max\_restore\_bytes\_per\_sec":"10m"}}

or

{"type":"fs","settings":{"location":"/var/ESBackup/snapshot\_test","max\_restore\_bytes\_per\_sec":"10mb"}}

or should the value be specified in bytes as the name indicates?
