Yes, and that would be the preferable way to do it assuming you have 
the drive space.

You may want to do periodic backups of the whole system more 
frequently than that, as there are always little changes that you're 
making there (application and system updates, and probably other 
changes as well).  In fact, it's best if you keep more than one copy 
of the whole system if you can - one older version, and one more 
recent version.  Just in case one of your backups isn't good.  (in 
commercial environments it's not uncommon to save backups nightly, 
weekly, monthly, and yearly, but that might be overkill for you.  I 
do it on my servers.)
