Where can I cheaply store data backups with the ability to use rsync?

Question

Backup

I am looking for a service where it would be possible to cheaply store backup copies of data from a laptop (books, sources, ...). About 50GB I used
a Yandex disk. Unfortunately, the webdav speed was very slow (a couple of tens of kilobytes per second). And the utility under linux hung on the directory during the first indexing (or at least did not show signs of life).
I would not want to pay a lot, about 100-150 rubles a month.
You also need the ability to synchronize data without downloading everything anew each time via FTP.
Yandex disk with the ability to connect via webdav would be ideal, but the speed is not the same.
