Stramit just finished a new SharePoint tool : Granular Backup Manager
from his blog:
>>> This App is the steroid version of GuiSmigrate ;)
You can manage all the tree structure of a WSS site : each site and sub site can have his own backup and his batch file.
very nice tool, saves myself some scripting ;-) .
beware! It can only be used on a pure WSS server (no SPS installed)
