Our blogs can be saved through Blogger. Here's the link to a post giving detailed directions, including screen shots.
I immediately tried the procedure, and it worked without a hitch. Since it only saves what's currently on the blog and scheduled posts, mark your calendar and repeat the procedure every month or two.
All you Blogger folks out there give yourself some peace of mind and save your blogs.
