Copy Database from Production to Development
Backup from PROD with COPY_ONLY, compression and restore it on DEV server is the best option.

Make sure to enable Instant File initialization to cut down the restore time.

Edit:


  I don't have a permissions to restore database. is it safe to use copy database ?


This might imply that you are not authorized to do such operation. You can ask your DBA to help you out once you have put in a proper support ticket.

Also, its quiet important to wipe out PII information when you do a restore on a NON PROD system - as @MichaelGreen pointed out.
