Cloud Backup providers

I'm working on tightening up my backup regimen and as such would like to include offsite backups. I cannot afford to house a server in a datacenter myself and do not have any friends with backup servers that I can use as "off-site" until I can afford that. All of this being the case, I'm looking for a cloud backup service provider but have no interest in housing my backups on Google, Amazon, or Microsoft servers, the best known providers of such a service. When I tried searching for general recommendations in this sub, all of the relevant posts I found were at least 5 years old, and considering how rapidly the cloud computing landscape has changed in that time, I thought it was worth making a new one. Any help will be greatly appreciated. Thank you all very much in advance.
