When I'm presented with such ultimata I tend to nod, smile
pleasantly, and continue my work on local disks or, if they're very
insistant, proceed to get another job.  I expect those I work for to
trust my expertise, not to second guess me.

No, they are working in a manner which they, in their professional
opinion, consider better for some reason, which reason they are
typically willing and well able to support.  They fact that you
disagree is incidental and largely immaterial.  They are, one would
assume by the fact that they are working for you, professionals.  If
so, why are you telling them how to work?

Do you second guess and tell your car mechanic what tools and
methods he should use with your car?

<...delete rant about NFS being a virus...>

Network filesystems are inherently unreliable and do not implement
standard semantics (don't even mention NFS locking) for intermittent
or disconnected operation.  As such they are suitable for posted
data -- compleated work that is ready to be viewd or shared by
others on an almost solely R/O basis -- a need which is incidentally
almost compleatly satisfied by web and FTP servers.  Network
filesystems: Avoid.  Avoid.  Avoid.  That way lies the dark path of
silent corruption, wasted work days, and midnight screaming
sessions.

Really?  I've generally found my workstations to be more reliable
than the servers that surround them.  It is a shame that so little
attention is paid to distributed backup tools, techniques, and
strategies, and that instead the problem has been glossed over with
the generic evaluation of "too difficult/expensive/uncontrollable".

Sure.  Management gets them when I consider that they are ready for
the world to see, as defined by the fact that I submit them, check
the code into a shared repository, post them to the file server,
etc.  Until that point they are just slightly-less-than-random bit
orderings, localised areas of reduced entropy.  They are incompleat
works whose import and value cannot be determined due to the simple
fact that they are statements that haven't been uttered yet.

When they're posted, they gain value and are admissable.

Consulting treating you well?

Sorry, you seem to have read some post other than mine.

Find a competent company.

And go troll someone else, by the way.

Yup, tho I would follow (and recommend) the same line as a perm
hire.

Nahh, I'm just carrying scars from prior NFS experiences, and get a
bit twitchy sometimes.

Its not a question of competancy, but of change rates and loads and
the resulting effects on _opportunities_ for failure.

You may wish to re-read my original post then as you seem to have
not understood it.

You know, J C, I wasn't going to say anything, but this is a rather
ironic claim, giving that your entire tedious rant was based on
attributing to me a position I do not hold and never stated.

To wit, you seemed to attribute to me an assertion that employees should
be informed they're not allowed to keep company-important work materials
on their workstation hard drives.  Wrong.  That I did not say. 

I was questioning the entire rationale of a company backing up employees' 
workstation hard drives.  Bad idea.  Way, way too many problems when any
company-significant work material can and should be on the fileservers
where MIS can properly look after it.  The implication was not that
employees should not be _allowed_ to keep their stuff on their "desktop"
boxes, but rather that they have no business coming crying to MIS about
losing six months' work to an accidental deletion or local hard drive
failure.  Therefore, neither does it make sense for MIS to promise to
back up those local hard drives.

Now, frankly, those details should have been flippin' obvious, and our
having this conversation has been a waste of your time and mine --
twice, each.  Enough, sir.  Please work out past traumas elsewhere,
without highjacking my points for lengthly irrelevant digressions.
