All of my backup clients, and the backup server, are on the same subnet
so that shouldn't be the issue.
As Jon pointed out since I probably want to do this as a one-time no
record backup, I might settle on creating a testing config and labeling
a tape for testing and going that route to have minimal disruption to
the normal backup cycle. Probably best, and not that hard to set up.
I'll give that a shot.

I recently upgraded the server side to 2.4.5 and a subset of my hosts
are consistently timing out on estimates each night, even after
doubling the time limit for estimates. The affected clients are
running 2.4.4p2. Is there a known issue here? Some clients also
running 2.4.4p2 are working, so I am not sure that is the problem.
amcheck reports no errors on any of the hosts.
I would like to debug this by not having to wait for the nightly
backup to fail but by just testing one backup target, tweaking, and
testing again. I could define another config altogether, but then I
have to load tapes for it, etc... is there an easy way to just force
a run, but of only one target, without adversely affecting things
when I go back to the full run?
Why not try a config backing up to disk and see if there are any
changes in behavior?
Further, any other speculation about why estimate timeouts would
start happening in a subset of clients but not other clients in a
config where the only change is a server upgrade from 2.4.4 to 2.4.5
which corresponded with a move from redhat 9 to fedora core 5 for the
server? Thoughts about the best way to debug?
Any commonality from a network perspective among those clients that
timeout - like they are behind a firewall or a particular class of
subnets and the likes?
