I have 2 internal hard drives. If I use TI9, I read I can clone a complete copy of one hard drive/OS too. If I then send or save it to my other hard drive do I have to disconnect one of the hard drives?then connect again to do the incremental backups even if I save it in the Acronis safe zone? I am looking for a simple solution for backups. If I have to unplug one hard drive it would be easier to buy an external hard drive and just unplug and replug when I want to do incremental backups.
