Don't worry about journaling. I'd leave it on for the backup: it won't hurt anything, and can help in some situations.

If you request an erase-then-copy, we'll duplicate the formatting of the drive from the source to the destination. If, however, you don't erase, we retain the properties you've selected. It doesn't affect the files within the disk (and allows you to do things like convert from case insensitive to case sensitive).
