that depends entirely on your needs. Copying away the Zope tree and the instances' products and extensions every time you change something on it and copying away the Data.fs every x hours isn't exactly hard, is it? And it requires less space. Having a VM lying aroung just to copy-over and run is also handy, but you need more resources. You decide. Design your backup/restore process well, when you need it you probably won't have much time thinking about it. > Interesting that a VM service would only require the RAM that Zope requires > normally. You would naturally think that the VM service would take up quite > a bit of RAM itself? I didn't say that. I just said, that respective to zope's RAM usage its irrelevant, whether it is inside a VM or not. Of course you need the RAM for the VM itself. --knitti _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
