RMAN incremental restore
Sure it is possible. I have done this dozens of times.
It is a simple RESTORE, then a RECOVER phase 5 days later. Or you can even run RECOVER periodically to keep the copy up to date.

Just make sure you do not mess up the catalog with the copy database. Usually I just restore the latest controlfile and use without a catalog connection to prevent RMAN registering restored copies of datafiles in the catalog.

Or use DUPLICATE if you want to use Data Guard as suggested.
