I have a home server that I’m using and hosting files on it. I’m worried about it breaking and loosing access to the files. So what method do you use to backup everything?
Some hosting sites advertise "unlimited" storage, but the fine print generally excludes "abusive users" from this policy. For web hosting, they'd probably consider backups of non-website data to a service intended for basic web hosting to be abuse.
Unless they have a home lab (sounds like they don't) or fancy expensive contract with a large cloud provider (unlikely), this is asking for trouble. Nobody offers unconditional data storage for free, its always a loss leader for another service and abuse will eventually get you banned.
I confirm that in the terms and condition they discourage the use as a private cloud backup and only to host stuff related to the website. Now.. until now I've had no complaints as I've been paying and kept the traffic at minimum. I guess I'll have to switch to some more cloud oriented version if I keep expanding. But it's worked for now !
