I know how to create the system image into an external drive where there has never been a system image before. But my question is when you create a new system image a month or week later, does this just "update" the old system image, or does it create a brand new image of the system? Just asking because the time it takes to create a brand new one takes some time.
I think I got it. Backing up files actually updates files inside libraries, personal folders, and inside the system image. I'm new at backing up my computer, but it's high time I learn how.
The smartest thing I did was start using an external drive for my data and music. Disconnect the drive and data can't be altered. Access is very fast. And I don't have to do any maintenance to the files. No defragmenting, reorganizing, etc.. Have 2 external drives, and one could be used as a backup file. I have been using external drives for quite a while.
All the hard disk on my computer contains are systems files and executables. I don't have to do maintenance on that hard disk very often. The external drive just plugs into a USB port.
