Is a "twin drive system" an external disk drive onto which you would save a copy an image of your Windows application every week or so? If so, this can be configured to be done automatically in specific intervals, can't it?That's pretty much it, though the secondary drive can also be internal, but I don't recommend that.
At one time it was standard practice to have one's system image backup drive constantly connected and one's backup & recovery software set up to take full system image backups and/or incremental backups at specific intervals. Since the advent of ransomware, this is no longer recommended practice (unless you're using a cloud-based backup solution such as Carbonite, to name but one) because ransomware will encrypt each and every drive it can find that's currently connected on a given system, sometimes even on a given network once it finds the first entry point. The last thing in the world you want is for your system image and/or user data backup drive or drives to be encrypted during a ransomware attack, as then they cannot serve their intended purpose. Current best practice is to have a backup drive connected in only two circumstances:
1. You're taking a backup.
2. You're restoring from a backup.
Otherwise, they should be offline.
