Did you verify it?  What happens if you run "Get-MailboxDatabase -Status  | select name, mounted" in PS window? Which version of NMM are you using?

Sure, but was that executed during backup attempt?  I'm not sure myself what is going on nor why, but obviously API gets an idea that DB is not mounted so perhaps running that command in loop while backup is running would be good to see what is going on and just to be safe on whether there is split brain or not.  Which CU are you using?
