I/O wait fluctuating between 0 and 2%

The I/Owait on our cloud servers at the moment are fluctuating between 0% and 2%.

This is because we have just switched on our new Idera CDP (Continuous Data Protection) and it is backing up every file on the system.

Once this 1st pass is complete, changes will be backed up every hour, this will significantly speed up backups which currently take 4-6 hours per server each day.
