volsnap error shadow copies deleted.

[nicholab]

Just had this error.

 

The shadow copies of volume E: were deleted because the shadow copy storage could not grow in time. Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied.

 

Why has it done this and just not held on to the other shadow copies if it can write in time?
