I have a windows 7 laptop with an 500gb Samsung 840 EVO SSD, this is the only drive in the laptop. I would like to attach an external 500gb Samsung SSD and create an exact bootable copy so in case if harddrive failure or corruption, I can simply remove my SSD and install the other SSD and be running as of my last backup. As far as the daily backups, is there a utility that will just image the backup drive with just the delta to avoid excessive wear and time? I searched other answers and it seems Windows 7 backup imager is not incremental. I also want to avoid the recovery-disk step. I just want to pop in the backup SSD and be off and running.
