Where is there an automatic backup of about 100GB with version control to another physical location from Windows for a low cost?

Question

Backup

Need:
1. Backup on a machine located in another physical location.
1.1 It is desirable that the backup management system is located on the server side and is protected from hacking the client's machine.
2. To make it all work automatically.
3. Version control.
3.1 Smart version control is desirable, but not so that the vir wrote a bunch of data, then on top, and so on 50 times, as a result, due to lack of space, all the data was wiped before the vir appeared.
4. Reasonable price. Yes, the price of blackbase in the form of $5 per month (which is equal to $500 for 10 years) is quite an adequate price when you backup an entire 8TB drive, or even a 2TB drive. But I appreciated something, I can clean up 300 gigs from my screw, 80 gigs will remain occupied (of which half is Windows), and I won’t lose anything much. In general, you need to backup 50GB, well, a maximum of 200GB (if with all sorts of rubbish), but not terabytes, as blackbase suggests. And yes .. I think that the price for a backup should be calculated not by months, not by years, but if so, every 10 years. the screws broke twice, but when it comes to HDDs, they usually die gradually, which is hard not to notice from the symptoms of their behavior (at that time I did not know about smart) and usually there is time to buy a replacement). In general, I assume that data loss is a very unpleasant, but infrequent event, and the cost of a backup system should be estimated in terms of 10 years. And now I would like to pay about 100 bucks for 10 years for a backup of 50 gigs with a smart version control system, moreover, in installments, because I don’t make investments for 10 years in advance. I understand that it sounds a little crazy, but 2TB can be backed up for $500, why then 0.1TB cannot be for $25 (even if it's for $100)? I understand why - the cost of advertising and marketing does not depend on the capacity of the backup, but surely someone is not so invested in advertising and marketing, but they are hard to find?

Maybe someone knows, maybe there is something close to my desires?
UPD1: Blackbase B2 only asks for 50 cents per month ($60 for 10 years) for a 100 gig backup. But they provide the API, not the final product. Can eat what free screw software on work with them?
UPD2: Here's what I thought... The backup system could be compromised by an evil developer, or someone else. And this can lead to the destruction of data both on the machine where the client is located, and on the storage itself, if in principle it provides an api for the backup system with which you can delete data.
UPD3: I tested two inexpensive cloud solutions (one from Acronis, the second from Backblaze and CloudBerry recommended by them) - both turned out to be raw, I don’t know what. Dampness is primarily in the overrun of the occupied space. That is, if you are not very active with the data, then you need to take 3 times more space than you need. Simply because they have very "smart" version control algorithms.

Answer 1

I have not seen a solution that satisfies all the requirements.
If in parts

1. No problem. The backup storage can be placed anywhere, as long as there is network access. As for hacking, it is decided by the rights, although you can make a backup from a remote machine.
   
2. How you set it up will work - any script added to the cron will provide what you want. However, any automation must be monitored, because it tends to break down sometimes.
   
3. There are many solutions, including one that will not overwrite anything, but simply send a notification about the lack of space. Although I must say that I have not yet seen a virus that writes a bunch of data, and have not heard of such a thing.
   
4. There are storage facilities with a reasonable price. There are those who fit into the amounts you voiced. But vaults are just storage space, not a backup system. Backup software needs to be selected and configured independently. But those storages that offer ready-made backup systems, out of the box, everything is expensive there, very expensive, because it’s convenient out of the box.
