[Zope] How to maintain an up-to-date mirror site in Zope? (not-so-newbie question!) question!)

[Steve Spicklemire]

Hi Alex,

   If the changes that are made are always 'one-way' you could rsync
Data.fs, or you could 'export' certain folders that could then be
'imported' at the mirror site. These could both be automated pretty
easily.  As you noted, if you take the rsync route you'll need to shut
down and restart Zope. If you do the export/import you can leave Zope
running (though you may want to pack the DB afterwards.) Another nice
feature of export/import is that you can have some parts of the site
that are managed at company B and other parts managed by company A. An
even better approach might be some kind of ZEO solution.. but I don't
know anything about ZEO other than the name. ;-)
