Cobian Backup, it's free.

No, you have to run macrium and do the image manually.  That's probably the worst thing about using it for backup's, however the best thing is it is a complete image of your drive so no reinstalling/downloading anything in the event of a drive failure.   What NAS do you have?  yes that is where you'd store the image files.

There's a ton of softwares that can backup your stuff, be it from simple files all the way to an entire drive. Even Windows's built-in backup feature can somewhat do this well enough.x
 
I used to recommend Acronis True Image. Because it was fast, result in smaller backups than most and is easy to use, but they have also moved to a God damn yearly subscription model instead of a "buy once, keep forever" as they used to, so I can't in good conscience recommend them anymore.
 
 
Like others have mention, Macrium Reflect is good.
But right now I use Paragon Backup & Recovery. Also free and can do incremental/differential backups of select files, folders or complete drives on a schedule. Backup encryption, splitting(to save on DVDs for example) and what not, is also available. Interface took me a bit of time to get used to, though.

I read the title and thought you meant a literal time machine equivalent.  I was going to say the closest thing I can come up with is that instead of waiting until you are an adult  and regret not listening to good advice, listen to it while you are young and you probably won't wish you had a time machine and to go back and fix it.
 
As far as a time machine equivalent goes,  I use macrium reflect and make a complete image of my important drives.  I believe it's bit more involved than time machine and you require the same space to store your back up as the drive, but it does mean that in the event of a catastrophic failure you have your entire PC from the last image taken.    EDIT: I should point out that you keep the image on an external drive or another PC on your network).
 
The other option is to buy a pre-built NAS and use their backup software that lets you choose all the folders and times it makes a backup.  This way if your PC dies,  you only have to reinstall programs, everything else (documents, music, files etc) can be restored using the same software.   This is a bit expensive, but it will allow you to do it for any PC on your network.

You can make arguments for IPS vs VA all day. In the end black smearing is there for most VA panels, but it's not something that will ruin your experience. IPS does have worse contrast and because of that is worse for dark rooms. It's simply not able to produce black, which can produce a worse image even with IPS's better colors. There are advantages and drawbacks to both technologies and there is no simple "x is better" like many people make it out to be. It all depends on what the usecase is.
 
There are too many differences that i could list here. If OP wants a complete summary of TN vs. IPS vs. VA then watch this video:
 
Another thing: Don't shop based on HDR support. The reality is that HDR currently is a load of marketing mumbo-jumbo and most HDR certified monitors lack the required hardware to make use of HDR content, so they're realistically not even capable of producing an HDR image. If you really want HDR then you'll have to spend upwards of $1000 on a real HDR display using a FALD backlight with hundreds (or better, thousands) of zones or an OLED display. For everything else: Don't mind the HDR spec.
 
For good and fitting recommendations we need to know what specs you'd want and what budget you have. There are likely better monitors i could recommend with this information.

There are slightly better and slightly worse options, but we're in nitpicking territorry here. Overall the LG 27GP850-B is one of the best IPS monitors out there. It simply isn't the best value. Just be happy with it and don't overthink it! 😄 

$300 is unbeatable value for that monitor. So you didn't just "not make a terrible choice" but a great one.

I don't see why not IPS. VA does have deeper blacks, but IPS has no black smearing. Or at least far from as noticeable than VA.
 

I'd go with -  LG 27GP850. Bit cheaper but spec-wise a bit better also.

Acer has many good models, the reviews are hard to find...

thank you for all the help! I got the Ideapad 5 pro with the 5800h cpu, should be a nice computer!

You’ll likely be looking student projects designed to teach a concept and that can usually be done with smaller stuff.  Might do to find out what the minimum spec requirement for a given class is. 

well if you know what school you are going to the school will know who is teaching the class and the teacher will know what spec they are aiming for with their projects

I translate that as”potato, but shiney new potato” sounds like a discrete gpu is not required, especially with a machine with a decent iGP.

Then, i'd add the Acer Swift X into the Mix: 
 

For my part I would say most things with a Xe or vega11 iGP will do. M1 is also on that level or maybe a twitch higher, but it’s out of the running so it doesn’t matter.  6/12 maybe just for extra oomph. A really good 4/8 would likely do fine though.  Keyboard quality and ruggedness will matter because it’s a Uni computer. There are also specifics involving electronic note taking in classes I don’t know much about.  Apparently microsoft proper is the best of x86 at that. I don’t know what the microsoft stuff is called.  Surfacepro4 is supposed to have it. Other things might.

You never "need" big hardware for studying. No Uni can expect you having a $2000+ workstation. Most people can do fine with 7 year old Laptops, or $500 models, in terms of Hardware performance.
 
However, if you have a higher budget, you might as well use it for stuff like build quality, Better screen, speakers, etc.
 
Ideapad 5 with Ryzen 5000 series is decent, it should be full aluminum. Take a look into the Ideapad 5 PRO 14". it comes with a 16:10 Display instead 16:9 (more lines of code, more content at the same time), 400 nits brightness, 100% sRGB, 90 Hz and a sharp 2880x1800 Resolution. Should be maybe 100-200 dollar more.
Or around 1000 dollar, Lenovo Yoga Slim 7 Pro with the same Panel, but more build quality.
Notebookcheck has it tested today: https://www.notebookcheck.com/Lenovo-Yoga-Slim-7-Pro-14ACH5-im-Test-14-Zoll-Kraftpaket-mit-guten-Akkulaufzeiten.552278.0.html
But it's german, however if you're familiar with Notebookcheck, you can get some informations about battery life, heat output etc.
 
HP Envy 14 (1920x1200 Screen, Tiger Lake-U, 400 nits Display) is also a good choice, if the Price is right. There's a really good Review from Just Josh on Youtube, also from other Laptops.
This is one of the only Laptops, where the Intel Tiger Lake Chip doesn't throttle, even unplugged. It maintains 3,8 Ghz under Benchmarks, and can beat many Intel 6-Core CPUs.
Also, 16:10 aspectratio is always great.
 
Not offering a 16:10 aspect ratio, but you could look into the latest (or previous) Models of the Thinkpad T series or more compact, X series (Intel 11th Gen at least, or AMD Ryzen 4000 or 5000).
Their strength is a sturdy build, repairable, good support, and good Linux support in case you need that.
 
But my personal recommendation is: M1 Macbook Air (Upgrade the base model to 16gb Ram, and SSD as you need 256 or 512). it's THE Perfect student Laptop, as long all your Applications run under MacOS.
High performance, very long battery life AND battery efficiency, and all the time Silent because there is no Fan. Great Display, great form factor, great resale value, great speakers, best Trackpad int he Industry, great everything that is not Upgrading and repairing.
C# should be no issue, depending what IDE, Plugins etc you gonna use. Jetbrains Rider works under Rosetta, their IDEs for many other languages has been updated to Apple Silicon already. Rider should follow.
Visual Studio is Rosetta only too atm, but they are working on a native version: https://devblogs.microsoft.com/visualstudio/developing-on-a-m1-mac-with-visual-studio-for-mac/
Visual Studio Code is native already: https://code.visualstudio.com/updates/v1_54#_apple-silicon
Adobe Stuff runs great too, the major Applications running natively already too.

Its pretty easy, and a great learning experience, I would recommend doing it, I think most people where afraid of doing their first build until they did it too. 

Order is pretty much irrelevant:
 

q90t? yea id grab that over the q80t for that price. again its samsungs flagship. so it will be better

I guess, after my experience with Q80T I kind of having a second thought on using a TV as PC monitor, it really isn't convenient but Q90T definitely better in most area and grand for that is a very good price - at least for me, TV and monitor pricing kind of differ greatly from place to place.
 
The Q80T I tested was already purchased at aroudn a grand and that was a crazy good deal already. But I would probably get another monitor just for my main destop work.

I'll see if i can find any demo on the tv, might make it easier to decide if oled is necessary 😅

Dunno about ur local prices but in the UK the 65 inch C9 released at around £3300, u can now get it for £1900.
The new CX 65 costs £2800
The CX 48" costs £1500.
 
So for a main TV / movie display , you can get a 65" C9 for only a little more than a 48" CX, and you can get the C9 55" for less than that at about £1300.
 
You can also look at the B9.
 
The cheapest i've seen a LG OLED go is the 55" size, iirc it went down to about £1000 with the B8 and B9.
 
The prices will likely drop a little more, and most certainly around Xmas. Its up to you if its worth the wait. I'd be surprised if the 65" C9 went below £1500.

I haven't got first-hand experience of the LG, but from some forums and general reviews the LG software/UI/processor is better according to most people, which can make a user experience much better.
For me, I use an Nvidia Shield TV on mine, and use that 99% of the time... so for me it's just a case of turning the TV on, and switching Shield on. For others they have said that source switching can be a pain, but tried it myself and didn't have any problems.

It is a possibility with OLED indeed. Here is an extreme test case: https://www.rtings.com/tv/learn/real-life-oled-burn-in-test
 
If you are not watching multiple hours a day the same content with static bars/logo's there shoudn't be a problem.
