I heard that Timeshift for Linux is the ideal software for taking a snapshot of the HDD, so I downloaded it and installed it.
Well, it looks really good but unfortunately I don't have enough space on my HDD. However, I do have a 500GB USB external HDD
and that's where it failed. It doesn't read the USB drive. On the Timeshift GUI there is a flip-down box for (I assume) to change drives.
Is there any way that I could get this program to copy a snapshot of my HDD on to the external USB drive?
Otherwise I will have to look for an alternative
