This story has nothing to do with why Linux would be any better than Windows. Sure, if you lie to people, then anything can be convincing. What if I had a firewall installed in Linux, wouldn’t you have had the same issues?
This is sort of the problem I have with a lot of Linux enthusiasts, when you have a hammer, everything is a nail.
Compared to Windows and MacOS as a client desktop, Linux still severely falls behind, but it is getting better. For a server, Linux is just far superior.
Oh God. Those are the 2 worst ones. They are mainly used for IT tickets, not for developing software. Jira isn’t the worst, but it does lack basic features. It’s just when companies use Jira you just know you are going to have to deal with a bunch of PMs who all they care about is velocity.
There are so many other simplified alternatives these days. Basecamp is one.
If you don’t want to use a hosted provider, you can at least just start using git. Just do git init. Then you can start commiting changes. This way, you at least have a history of changes. Then just back that folder up like normal
You can use a few tools.
RSync
Rclone - probably want this one over RSync though.
Tarsnap
Duplicati
Restic
There’s obviously a lot more, but these are some of the more popular ones.
Now you need a way to back it up. Probably the best way is to tar it up first and then dump that file. You can also get something like deadmans snitch to ensure backups don’t break.
As you mentioned, if this is just source code, then the best thing would be to create source control and have it set up that way. Then you automate it and deploy the code when you make updates and have a history of changes.
It sounds like tarsnap is your best bet though. It will be the cheapest.
You can also backup to another storage provider like Google, Dropbox, or even AWS s3. S3 can get costly, but you can archive everything to the glacier tier which is pretty cheap.
Yes, you have iptables and nftables, but it’s not always enabled. So, when I said installed, I really meant enabled. I 100% agree with what you are saying though.
Unfortunately a lot of places just have shitty IT and people go rogue because of it. Some people are just impatient though as it sounds like in this case.
You also have things like apparmor and selinux. If those are enabled, you might be chasing your tail trying to figure out why something is not working. You would need to know where to look and how to fix it.
