[Zope] backing up Zope2

Is running "Pack" in Zope still the best way to backup a site? (other than export). What I'm thinking of is like the reverse of utilities/load_site.py. I was trying to FTP an entire Folder and could not. When I 'get' a Folder, it says 550 Error opening file but I can cd into it and 'get' it's contents. Is the Data.bbb format anticipated to change any between Zope 2.a2 and Zope 2.0? Just trying to avoid losing any work. Alex Rice | alrice@swcp.com | http://www.swcp.com/~alrice Current Location: N.
