Running Backup/restore twice?

I'm restoring my wife's computer after a hard drive crash. she has an external drive backup. We ran backup/restore, but I'm not sure if we chose the right option for the "copy/replace" options, for files already present on the new computer. We chose to not replace any of those. Now I'm wondering if we should have just chosen to replace all files. So, could I just run backup/restore again, this time opting to replace all files with those from the backup?

Thank You, everything looks good so far. Leaving well enough alone!
