MySQL Cluster NDB Backup performance

Hi there ,

I have been trying to backup an NDB cluster to NFS storage.

The same NFS share is mounted to the same location on all of my RHEL NDB nodes (there are 6).

Running a backup with a simple "STARt BACKUP" is very very slow. The IO spikes to 200 MB/s every 60 seconds and then does nothing for the remaining 59 seconds.

Is there anything I can do to speed it up ?

I am using 8.0.24 and have recently upgraded to 8.0.25.
