The backup (saveset ALL) with client NW 8.0.1.1.build 132 to server NW 
7.6.2 failed on 2 of 3 clients with this error:

That's not a hopeful sign

This client above is Win2008 R2; a Win2012 client failed with the same 
error. Yet a 2nd Win2012 client backed up without error. I did restore a 
file to one of the servers that failed with this error, though. 

When I get back in the office Thu, I will have to investigate. We may have 
to delay the NW 8 upgrade to the storage nodes only ...
