Acronis is still our favorite software for cloning hard drives, however some alternatives that others enjoy...
*Macrium reflect...probably the most recommended free version you'll see out there.
*Paragon has a free version of backup for home users (I've used their business products a lot, very similar to Acronis)..although it won't clone, it does backup.
*EaseUS ToDo backup
*Clonezilla..an oldie.
*AOMIE Backupper
*Windows own native backup
