that is true only with a fast connection to the cluster, as soon as you 
have higher latency this will bite the users..

also one problem is if a node gets offline while clicking, then this
blocks you a few seconds for sure...

yes, this is a problem that remains, but is there not a task log entry 
for backups?

could work yes, or a model window that gets completely masked instead of 
the grid..
