Usenet backup, automatic solution?

Question

Backup

I have a "home server" on ubuntu server with quite a lot of files (mostly movies). And I would like to organize a backup of all these several terabytes of data. I tried several services for online backup. Most of them do not have a Linux version. They also do not allow you to back up network balls (that is, it is also not suitable to run under home Windows). But the main problem is speed. The last CrashPlan I tried uploads files to the server at a speed of about 100 KB / s (it's hard to imagine how many months a backup will take ...), and downloads about 1 MB / s (not bad, but it will still take a lot of time).
And then it occurred to me to try using usenet for backup storage. Files from there I have downloaded at maximum speed. The only problem is that it is not clear how to automate the backup process. It is necessary that changed and new files be tracked in some way, packaged and uploaded to Usenet. And the history of what has already been uploaded with nzb files must be stored in some form. Plus periodic availability check and reloading of old files.
Maybe there is some ready-made solution? Under Linux without GUI or under Windows. It would be ideal if there was some program that would do everything the same as the same CrashPlan, but would use usenet servers for storage. That is, the entire backup process would be transparent to the user. But I doubt there is such a thing...
And if there is no ready one, then ideas or suggestions on how to organize a backup. And then the second server for backup is expensive to assemble ...

Answer 1

usenet is which newsgroups?
so it's not yours, how do you imagine your public backup, or let's say when your backup is deleted?
And in general, the use of navryatli will allow you to steal terabytes, this is not what it is intended for after all.
Buy yourself more screws, assemble a second computer on an atom and back up on it.
