When SSD's became the hot ticket, I bought a high dollar one for my OS drive. Not trusting new tech, I also became a backup fanatic, using one internal standard HDD, and 2 external portable HDD's that are backed up every night. Sure as shootin'... about 8 months later the SSD locked up... the controller went bad. Thankfully, with a new SSD installed, and a 30 minute recovery of my data from my backup source, and I was back in business, with less than a 24 hour loss of data. If I was a backup fanatic prior to that, I became a backup madman after that.
Sure, I have my shooting and load data in an Excel spreadsheet... as well as a hard copy (I don't like to read off the computer... I like PAPER!) But I've also got full images of my OS, as well as my actual files themselves copied onto backup drives. I do NOT trust 'cloud' anything... all the cloud is, is someone else's computer, and you are putting your data in someone else's hands... which I have a problem with, given security breaches and such.
My actual load and shooting files are on a thumb drive... I don't have anything 'shooting' related on my internet-connected computer. I plug it in when I need to update something, and unplug it otherwise. It also makes my data portable. Thumb drives, however, are notoriously unreliable.... sooooo... I have a backup for my thumb drive, too.
What the other posters said is correct... if your computer is configured for it, you may very likely be able to roll back and recover your data, but if the corruption is local (your hard drive,) your files may be borked all the way. Corrupt files can also be a sign that your hard drive is on it's way out... something else to consider.
