Back up your files to an external hard drive every night after you finish working. You never know when your computer might decide to crap out for good and it’s never guaranteed your files can be recovered. External hard drives with multiple terabytes of storage are pretty inexpensive these days. I started backing up my laptop a couple years ago. I sleep a lot easier now. I prefer a compact external drive that I can disconnect from my laptop. I like knowing that it’s completely unplugged from the laptop so there’s no chance of it randomly being corrupted or hit with a power surge.
