If it's on the same machine, it's not a backup. They should not have been on the VMs.
"looks like 100% data loss. thanks.. crystaltech.. :("
"you sort of assume your hosting company is competent. That's not a safe assumption in my experience."
"looks like it's 100% internet search caches for recovery. Any tips on recovering images, which typically aren't cached?"
"I had backups, mind you, but they were on the virtual machine itself :( I am OK on post-text, getting the post images is much harder.."
Looks like I was wrong on the SQL Injection cause!
ugh, server failure at CrystalTech. And apparently their normal backup process silently fails at backing up VM images.
I wonder was else was on the physical VM server besides the SO blog and Coding Horror. Also, it's curious as to why the VMs wouldn't have failovers.
