Windows 10
Make Acronis True Image backup on the hard disk.
But you need these files another copy on a portable hard drive that from time to time connect.
Acronis is a function of redundancy backup, but it works when it is backed up and connected a portable HDD (for redundancy).
My situation is different.
I need to configure so that:
I connected my portable HDD, and if there are any changes to the PC in a specific folder, they are copied to a portable HDD.
Prompt the program which can be put in the startup to do it automatically, when you connect a portable drive (copy will be created backupi *.tib)
