GRIEFED! NEED ROLLBACK! HELP

PLEASE HELP! I logged off of my server for 3 hours or so, came back to find my friend had used a combination of TNT and Ghasts to blow up my huge city, this happened before I had a Rollback plugin installed. Now I need to perform a Global rollback or just any rollback which will fix the Ghast damage and his damage. I've got CoreProtect, BigBrother and SWatchdog, but none of them are really effective. Am i doing something wrong? I need commands, good ones.
HELP!

for coreprotect do /co rollback then the name t: then the ammount of time then r: then the radius should work

All those plugins suck! LogBlock FOR THE WIN!

Good luck though, I'd knock him in the face before you roll it back though.

Nothing you can do unless you have backups.

Amen to that, All these new plugins are for noobs. Long live LogBlock
