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.

decide if it's worth it for the price.
I'm not saying it won't work, I believe it will. But if you have any problems down the line, tech support will be limited as to what they
can do
since the simulators don't have support contracts.

Hi,
One additional question regarding this topic. We're planing the usage of netapp sims, for somekind of small data
replication
from our central datacenter to home offices. Today we're syncing the data with unix tools, but we think about
implementing
a netapp sim, because of some very useful netapp functios. The amount will be about 1-2gb, which has to be mirrored each day to
the home
offices. I think we can optimize speed and and we would be able to throttle
bandwith
with the usage of the simulators snapmirror. The solution will be a blackbox for the users, just only for automatic
syncing
the data from our headquarter to their private office. For this usage, netapp functions provide very powerful and useful
methods,
thats why I'm thinking about this...
What do you think about these ideas? Are there any restrictions, which
do not
allow the commercial use of netapp sims? Or do you think it's just an unrealistic idea, to implement such a
solution?
Regards Andreas

No. The simulator liceses only work on simulators, not real filers. Licenses are priced by platform, but older (i.e. EOL platforms) may
not have
prices.
There's been talk about "home use" licensing, but I'm not aware if it
was ever
implemented.

I know this probably doesn't work. But if I purchase a old filer,
would
the simulator licenses work on that? How much does the licenses cost anyway?

Thanks, I thought that would be the case.

No. The simulator is limited to 28 1GB virtual disks.
