Unhappy [Q] unfortunately the process com.google.process.gapps has stopped after cwm restore

I have tried flashing other clockwork recovery's and and backing up and restoring and i keep getting this message one after another. the only way i can get rid of this is if I make a full swipe. It's not the biggest problem, i just feel unsafe if I ever want to flash a rom and not be able to restore old backups.
