hmm. … backups … you should always check backups before depending on them.
I backed up my site from my previous hosting company assuming it had copied all the folders where my wordpress installation was … all the misc stuff like images, etc
guess what, it didn’t !
thank goodness for my SQL backup which retained all my posts and comments, but alas, no images, no wordperss themes.
So next time, I will do what I did when I worked in IT, check the backups work before you need them
Update Jan 1, 2010
All is well, the “home directory” of my web site was archived in a single tar file … 
saved!
and I now have a backup of my website off line !
