Clone windows on external disk

[mogens]

Hi
I'm running windows 8.1 from an external SSD disk and want to try windows 10.
All runs fine now, but to be sure I want to backup/clone my current installation to another drive if anything goes wrong. Is this possible to make an bootable image to copy/restore back to the SSD so everything works as before?
Thanks

Give Acronis True Image a look. I believe they also sell a stand alone version in addition to the subscription model.
