Retrospect questions

[RobinS]

Using Retrospect 6 on latest OS X.

I want to back up certain files from hard drive A to hard drive B.
If something is not on the original that is on the backup, that should be deleted. If something has a newer date on the original, that should be replaced. Everything else should be ignored.
Sounds simple.

You would think that to back up something you need a source and a destination. I can't imagine most people backing up every single file in a folder(s). Yet I can't seem to find a way to pick which files to backup.

I would have thought most logical solutions would involve using commands that are commonly used on Apple software. Hold down the Command key and click which files to highlight, etc. But no. Its got to be different.

Am I missing something or is this yet another example of the inconsistancy of Apple compatible software?

Can I use Path Finder or Finder to do this somehow?
