Oh God, Zip drives. Brings back so many memories. It was the glorified floppy disk.
Zip drives were the stuff back in the day

OP, you should have a backup strategy regardless of your intent to install Windows, however I would never recommend doing anything with a partition or Boot Camp without one
Unless of course you have nothing on your drive that is important to you
This forum is littered with threads from people who have lost everything without a backup
Disk storage is always cheaper than data recovery
