I use CloneZilla https://clonezilla.org/ to move to new drives, so you could use it to make a bootable clone of your current drive. I would recommend booting once from the new backup drive just to confirm that it worked correctly as I've seen the clone complete but something went wrong and the clone drive wouldn't boot.

I just restored a backup that was created with the backup tool included with Windows 7 after I installed some updated drives caused Windows BSOD on bootup. The built in backup tool is nice as it allows you to keep multiple backup images, but you can't confirm that the backups will work like you can with using a cloned bootable drive.
