TWRP Backup and Restore?

Does backing up my phone using TWRP without the data partition fix the phone if it somehow got the OS removed?

Depends what got wiped or messed up. If it was just the System partition, then yes you can backup and restore System which should solve your problem.

It certainly helped me when I was trying to install the KangVIP rom. I couldn't initially get it to boot, so I restored previously backed up stock Boot and System partitions and all was fine.
