Question about DB Backups
Using Jamroom
OK I found the root cause with the DB not being backed up, and have fixed it in version 1.1.0 which is in the marketplace. I updated your site, and have run a DB and module/skins backup no problem.
I also manually was running a profile backup, and it was around profile_id 14,000 when my system locked up here and I had to reboot, but it looks like it was working no problem as well. Try running the profile backup again manually and it should complete (it will take some time, but should complete).
Hope this helps!
