Space-saving backups with sparse files or squashfs
On November 4th, 2015 In Linux
Recently I had some serious trouble with my Windows-based Laptop (yeah, I know...).
That’s when I decided it’s time to take a snapshot of the whole SSD. After all I don’t want to reinstall everything from scratch if (or should I say when?) my Windows installation decides to self-destruct.
