Seagate and Western Digital offer a version of Acronis, which

The WD version at least doesn't demand a WD hard drive, it's happy
with a USB WD disk which I use to store the images, even though my
hard drive isn't WD. It complains initially that it can't see a WD
drive, but gets on with the job when the WD USB disk is plugged in.
