DerStrom is correct.
What's missing at the moment is unrecoverable from my end. It's attachments that from January, 2012 to December 2012. I've started to contact members with a list of specific blogs and articles which have missing files and requesting that they re-upload. I will be doing the same for forum posts in the next day or so. But if you wish, you can do this without waiting for the email from myself.
It is a very regrettable situation. And to prevent such a thing happening again I've setup a new backup system that automatically synchronizes all files to a remote location every night. This wont happen again!
