You're absolutely right about all this. I have indeed a back-up of the
last two days, and I felt really safe with this. The only thing which
went wrong is that I haven't used svn for a few weeks and don't know why
the base got corrupt and hence I didn't notice it and back-uped the
corrupt DB. I guess that I'll add a daily incremental dump to another
backup procedure.
Anyway, I'll keep on using SVN since I find it being a lot easier to use
than CVS and it's also really more versatile :-)
