I wouldn't mind learning Linux, I'm just not motivated to do it. There's no work benefit for me, and I've never come across something in personal use that made me wish I knew how to utilize the command line. Maybe if I knew more about what's possible I'd be more interested. I pretty much stay away from it unless I'm trying to fix some little issue and I've looked up how to do something.
I have to use the command prompt in Windows sometimes for Python stuff, for work and when I was in school. But I mostly don't use that either.
For me it's mainly just that it's free, I know how to use it, and some of the "odd" use cases I have can be done easily. I keep one mini PC that is essentially my home "server". That was the thing I was complaining out a few weeks ago because the hardware had died and I needed to buy a new one, and ran into some weird technical issues trying to load Linux on it because of an old corrupted USB stick.
For example, I was playing around for a while with something called RaspberryPints. It was a Raspberry Pi based web server that would allow you to broadcast your beer tap list to a laptop, tablet, or phone. The Raspberry Pi was... Unstable. It would get corrupted from time to time, requiring a complete reinstall. But because I had a Linux server sitting there connected to my router, I was able to simply install the apache web server and the RaspberryPints web content onto it, and suddenly I had a much more stable web server for my tap list.
Could I do that in Windows? Probably. But the sorts of projects that people create for this sort of thing are usually Linux geeks like me, so being native to Linux just makes life easier for me.
When I gather the money, I want to build a new desktop with 4 hard drive spaces. I don't like dual-boot, partitioned-drive setups because I've found it causes some glitches on the Windows side. I'm gonna install Windows on one drive, Linux on another, and my files will be located on a third so I don't have to reload everything every few years when a Linux distro stops being supported and I have to install a new version. I'll leave the 4th blank, but eventually I'd aim to make myself a Hackintosh. For as much as I dislike Macs, it does have music software I like that is simply not available on any other platform.
This portion would be a good use for a NAS for backup, instead.
And now that I'm working through this miniPC build, I'm going through and finally cleaning up a bunch of disparate personal file sources (partly pictures, but other stuff too). I want to get it fully organized for backup purposes.
That miniPC will have local storage, will have a USB HDD dock, and then I also have a NAS. With Linux, it's trivially easy to set up a cron job (regularly scheduled action) that will use a command line based rsync command that will make sure that all copies of these personal folders remained synchronized so as I add new files or pictures, I won't have to manually maintain both the local but also the backup copies. And then I'm looking at using cloud storage [final safety location for my personal files in case my house burns down lol], and many of the cloud backup storage providers have Linux clients for synchronizing with their service too.
If your files are important, I'd rather they be stored both on your primary storage / desktop (one copy) and on external storage or NAS (second copy) and on an offsite location (third copy). It's the 3-2-1 rule for backup.
