This seems to be based on EaseUS backup apps, using EaseUS drivers etc. Most of the files are in the program's folder -- the exceptions are the 2 EaseUS drivers added to Windows\ System32\ Drivers\. Mainly because of the drivers I recorded 172 new registry entries.
While I don't see any faults with AweClone 2.6, I don't see any advantages either. The difference between cloning & backup apps is that the backup app will write the raw data to an archive [usually a VHD], while a cloning app will write that data directly to another disk or location. I prefer performing a disk or partition image backup before doing anything major. Restore that backup to a different location or disk, & you've got a clone. It's more flexible that way, e.g. when you can't connect 2 drives at the same time, & you've got a backup in case something goes wrong, but the choice is yours.
Note that Windows is not always cooperative when you want to restore a backup or clone a disk or partition when the target disk is already internally attached or installed. It'll often require a copy of the software you're using on a bootable USB stick, or the basic contents of that USB stick copied to the hard drive with the boot loader modified. For that reason I recommend Macrium Reflect, free or paid versions. If the target disk isn't internally installed, a USB drive dock works fine.
Note also that Windows adds a unique ID to each drive partition, and you cannot have 2 partitions using the same ID, which happens with a clone -- Windows will ignore it. You can usually open Control Panel -> Admin Tools -> Computer Management -> Disk Management, right click to the left of the ignored drive, and click Online. That should cause Windows to issue a new ID.
