In my research I found two other people
reporting 49’s when running backups after an update.
Both on older versions ( as far back as
3.5)
And both of they say that it just fixed
itself.
Well…. Mine has just fixed its self.
I was testing at 4:00 pm and they failed
with 49’s
At 4:30 pm they worked.
Upgrade some more servers and they worked.
I asked everybody I could if anything was
done.
I have never been able to find a reason
for getting the 49 return codes on those servers.
But they are working now
