Nick,
Don't get me wrong. This was just an idea for an alternative, you
described below.
These ideas with netapp sims should be used for field stuff or things
like that.
It is not planed for whole branches, only for several people, that's why
a real filer doesn't make sense and would be completely oversized.
So I'm looking for a solution to optimize these things and netapp
functions may improve the whole process.
I want to give it a try, if it's really competitive with standard unix
methods, that are already well proven.
Of course, support questions and license restrictions are other points,
we have to deal with...

So this data is obviously important to you, and something that you want
to
protect, this is why you're doing offsite data replication. I would
think
you would be much better off buying a filer, but since you're using the
simulator, I'm assuming that's a no-go. I'm assuming further, since you
have
the simulator, you have access to a unix/linux box to run it on. Here's
what
I would propose as an alternative:
Mount the volumes you want to sync off site on a unix box.
Open port 22 on your firewall to the remote site you want to sync your
data
to.
Follow the guide below, but add the option "-e 'ssh'" to the rsync
commands,
and set the source to be "ip.of.unix.source:/path/to/mounted/volumes"
and
the destination the location on the remote destination's unix machine.
This is a fairly straight forward process and uses standard methods
common
for doing backups in the unix world. It will preserve your premissions
and
allow you to recover from a specific point in time, just like snapshots
do.
It's not *quite* as nice, but I would imagine it would be preferable to
relying on a sim. Obviously, it does require a certain comfort level
with
unix, so your mileage may vary.
