[Q] restore backup twrp topic

I made a backup of my stock rom on my fido i747 before installing cm11. I made the backup using twrp but now that I installed cm11 twrp was removed and I'm now running clockwork mod. What's the easiest way to go about restoring my twrp backup? I'm guessing I just need to reinstall twrp and restore my previous backup...
Any help would be greatly appreciated.
