database versioning

Hey any admin should know this stuff cold but I'm a little fuzzy, hope you
can help!
I have a database mydb, about 5gb.
I want to keep a copy of it on the server, but as mydb_old.
(yes I have space for it!)
What's a good way to get it there, database copy wizard, copying files,
backup/restore?
Thanks.
(I want to keep the original mydb also, with the same filegroup filenames.
I'll do further work on mydb, but may want to reference the old mydb_old)
Josh
Tibor,
Thanks.
