Question Quick question about backing up

I've been using SuperDuper for many years now (and love it). A few weeks ago our hard drive started acting up, so we switched over to using the backup as the main system. I just found out that the hard drive isn't the problem but the enclosure, so I put the original hard drive in a new enclosure and now it seems to be OK. I would like to keep the original hard drive as the main system, but there is now two weeks worth of new stuff on the backup. So here's my question;

Original hard drive has 3 files on it; A, B, and C

We do a backup and our backup drive also has A, B, and C

Then we switch over and start using the backup for a few weeks so now it has files A, B, c, and X, Y Z.

If we use the backup as the source and copy onto the original drive, will it copy over just files X, Y, and X?

The reason why I ask is that there is a program on our backup that seems to be corrupted and does not work. However the copy on the original drive does work.

I don't want hurt the good copy of the program (on the original drive) by over writing it with the corrupted version. Hope that makes sense
