Backing Up Blogger Blogs
As for transferring to Word Press or another platform … although the migration tool used to work, we tried just after the new Blogger appeared and found that the tool simply didn’t function any more. It may have been the volume of posts, or it may just have been changes in the way the Blogger menus work. Word Press appears to extract the posts by navigating the menus in Blogger, so when the menus weren’t what it expected it threw a tantrum and refused to migrate posts. That’s not to say they (Word Press) haven’t fixed it now though. Has anyone else tried recently?
If you have an existing blog and simply want to back it up you could simply browse each of the archives (monthly archives) and Save (As) the web page to your own PC from your browser’s File menu. A bit laborious if you have a large blog but once you’re up to date, just save the previous month’s on the first of the month and away you go.
Alternatively you could use a tool like this http://www.httrack.com/ that will crawl a site and back it up for you via http. If anyone has tried this or any other tool I’d be interested in their experiences, good or bad.
