Can a Sim be saved client side?

Can a Sim be saved client side? Asking cause been doing some reading on Google about sim back ups and basically this is what I am looking to do, but not sure if there is a way. Ya know most MMO's the world is saved on your hard drive on client side and with SL the world is ran server side. Obviously I don't want to save the whole world of SL on my drive, but like one or two sims I do combat in I was wondering if there was a way to in order to reduce lag. Correction a way to in a format where you get better game play, but also aren't ripping peoples crap. I mean the whole waiting for stuff to rez when ya run from one side of a sim to the next sucks to be honest. So was looking for a way to have it already on drive and then it just changes as that sim updates. I see alot of combat systems, but I find this really isn't the best suited game for hard charging combat. Did a raid once in SL and I did good to step out the door let alone kill anything. lmao

no, you cannot do this.

theoreticly someone could make a client that caches the textures and prims better but that would only be usefull for people that stick to a few sims.
I guess that is why it has not been done yet, not many people stick to just one or two sims.

Well LL has been developing a standalone server...

This ties into their other post...

OpenSim - which is kind of opensource clone of SL that I believe has some informal involvement by LL - provides a free downloadable sim you can run on your own computer and even connect it to their grid. But it's not easy - I haven't succeeded in doing this yet! But all you get is an empty island and a default avatar - you'd have to make everything you need on the island or for your avatar from scratch.

The Meerkat viewer http://www.meerkatviewer.org/ will allow you to transfer objects you have created from one platform to another apparently. Haven't tried it myself but looks promising.

While bree conifer and ee are right it does not solve the problem of the OP, spike wants a prefetched sim image to limit the rez time not have an actual copy of a sim.

when you look at clasic mmorpg setup there are two ways in wich it is solved, either the needed data is preinstalled on the HD or it is fetched during the connect time, these two options do not work in SL due to it's multi server layout and user created content.
prefetching would make tping to slow and preinstalling is not posible with usercreated content.

I would love something like this, maybe a set of customized caches? So that I could choose my home sim and maybe a few others, and tell it to keep textures for those sims saved regardless of how many other places I've visited and have it NOT empty when I clear the regular cache. I confess I don't know much about how caches work; I've always assumed it was just based on which objects in the cache were used most recently. But if that's true -- well, most recent doesn't mean most frequent or most important. I really don't want 500 textures from that mall I just visited replacing my home textures in my cache.

Can't have that Rihanna. That would be too smart.

I do all my SL building in my own Opensim now. The biggest benefit is that in Opensim there are commands for backing up the entire sim. I then transfer my builds to SL using Second Inventory (but will also try the Meerkat viewer). Using this technique I always have a backup of my builds, and my sim.
