Whilst this is a new site, I have been running a site for my photography for a number of years. Recently, as part of the build for this site, I decided I should upgrade the core system the photography site runs on to Drupal 7. For various reasons this went wrong. Whilst I had a backup, it was incomplete for several reason. For a time, I felt that I had lost all the content for the site. This was naturally concerning and it made me realise that I had not made any effort for source control.
