Thanks, I’ll look into Xamp.
In the meantime, I see a couple of potential problems with your second suggestion. Perhaps you can suggest workarounds.
The first is that I would not have access to my blog for reference if I were off-line, unless I maintained my own hierarchy locally which would be redundant.
Second, I plan to eventually install Gallery so that all my photos would be going into my database. The backup would be gigabytes in size. Since I would want to run the backup daily, this would be problematic.
