I had 90+ hours in Fallout 3, as well as tons of other saved games, and my hard drive failed. This was back in 2010. I was so crushed. I can't believe I lost all of those save games.
I still haven't beaten FO3; honestly.
You gotta back that ish up.
I used to use an external drive for backing everything up but then one of those failed, too.
It was okay, because the hard drive hadn't failed, but I had to go get another external and then back everything up again.
Then I started researching cloud storage.
There's a ton of free and paid storage options out there and I recommend them for a couple reasons:
1. If a meteor crashes into your house and destroys both your PC and your external backup, the online backup is still there.
2. They have backups of their backups of your backups, because that's their business, so you really have the absolute smallest chance of losing your data.
(Note that if you invest in Backblaze through the link in this email, I will make a small commission at no extra cost to you.)
Personally, I use a service called Backblaze
because they're cheap ($5/mo per computer) and reputable.
A lot of my friends use them, too.
But, if you don't want to pay I don't blame you.
You can get free software that will automatically back your stuff up to an FTP server, Dropbox, Google Drive, etc.
You can find it in a quick Google search.
Make sure you back your stuff up so you don't lose your save progress.
Imagine being 2/3 of the way through Elder Scrolls 6: Morbliviorim and losing everything.
The people who had been watching your stream will be SUPER bummed.
Or worse...imagine losing the video files of a YouTube vid you've been working really hard on.
BACK IT UP BACK IT UP BACK IT UP.
