What cloud backup solution are you using? A lot of them offer additional protection that would keep a history of your files. You can essentially say "once a week create a point in time recovery of all my files" and then you could recover your files from that point in time.
This usually costs extra, and it makes sense why. They're essentially keeping extra copies of your data for you.
How that is configured allows you to determine your RPO, or recovery point objective.

So you can decide how much data you're comfortable losing by determining how often those point in time recovery events happen.
Did that make sense?
It does make sense. Thank you. I appreciate the link!
However, my cloud usage is purely as a proxy/load balancer, as none of my cloud providers hold any actual data. They're just routing traffic, and all data/processing is on premises. What I'm interested in, is how to setup something like what you describe, but on premises also. From a design stand point, if I wanted to protect myself from a ransomware attack, obviously my cloud backups would be lost because they're a mounted filesystem during a backup eventually. So I don't know how to wrap my head around handling this, just storage design wise as specific tools I can figure out. How does one create a recovery point, and keep it safe from something like this? Just image the entire file system from a live booted offline environment? Feels like a chicken-egg problem to me.
By definition a disaster recovery solution needs to be geographically separate. You're protecting yourself from catastrophe, and some of those scenarios include your main location burning down, flooding, being hit by a tornado, etc etc.
So you either need to collocate systems with a friend who you trust, purchase colocation services from a provider, or use a cloud service to achieve what you're looking for to truly have a DR solution.
As far as how to do that, the main idea is to have that point in time available on a system that, even if you get compromised, the backups won't. The old school method here is to use an external hard drive or a tape device, and physically store that offsite. So like use your regular backup mechanism, and in addition to what it's doing now schedule a daily/weekly/monthly job that backs up to this other device, and then store that away from your main location.
That's essentially the idea though, and there are any number of solutions you can use to do it.
