Drupal vs Joomla! part 2

Well, I now have an embryonic website.  And I've got to grips with the document structure (actually, it makes a lot of sense to me).  User access permissions seem to be more configurable than the default state in Joomla.

Unfortunately my Ubuntu laptop threw a wobbly this morning while I was editing menus, and that had the effect of damaging the database.  Had a bit of trouble repairing the damage, but all seems to be well now.  

Which of course brings with it the question of backing up the website.  I can't see an obvious way to do that (other than manually copying the files and exporting the database via PHPMyAdmin).  Guess a spot of Googling is in order!  On the other hand, the University requires I stick to a defined set of modules, so this may be an issue...

I've selected a relatively plain theme, and will set about tarting it up a bit. Personally, I prefer quite spacious and essentially white web page design, so I may stick with that - and it'll be easier to edit the CSS file to make it "brand compliant".
