My toon has been erased AGAIN

Hi peeps and admins...

Now that I'd decided to stop playing Pandaria, and seen WoTLK more active than ever, I just checked the Undead mage I left in Lordaeron server like a 2 years ago, to play with him again. And guess what? Is the second time one of my toons is erased in WoTLK! The first time was understandable cuz of the DOS attacks, that year when ALL toons in WoTLK was erased. But this time is for what reason? Disgracefully, I begun make backups with the new WEBS system like 3 months ago (to save my 5 toons in Pandaria), but now seems like pain to level and provide all good stuff to a WoTLK character again. Can anyone explain me if I can recover the second-time erased toon? Any support will be appreciated... =0)
