Rescue disc for macrium reflect v6 home edition question

Do I need to create a new rescue disc for each image I save on my backup drive or, does the first one created work for all the saved images? Thanks!

You just need the 1 Rescue / Startup Disk...
after each marcium update - you will want to update your resue disk as well (create updated Macrium Rescue dsik.)

Just the one disc, it boots into Macrium then you can select what image you want to restore from your drive.
