It would be really nice to have a full backup / restore possibility for WordPress. I have been spoiled by Joomla's JoomlaPack so I'D like to see something similar for Wordpres, too.
Here's what it should do:
- zip up all files or selected files from the server
- offer alternative archive solutions (file format) for large sites where zip archives might get too large and blocked by the host
- include sql dumps in the backup
- include easy restore possibilities like unpacker file + backup archive = easy restore
