New to Linux and using Mint 17.2. Started with persistent Live USB that ran out of space after a week. So made a backup of everything (entire filesystem) including the casper-rw file, created new Live USB with casper-rw partition instead of file. This currently works.
Now I want all the stuff back I had from that week of work. I want my programing includes and libraries, my themes, backgrounds... everything.
How do I do this? And how should I have done this if I was still in the position of just running low on space?
