My server rack is located in an uninsulated attic with two tiny windows. I haven’t measured the ambient temperature but I think it’s over 40°C. Yesterday one drive in my storage server reached 65°C - so for today I have shut it off until the rain comes. Fun times.
The question you’re asking is too broad. Every tool somehow differs from the others, but listing all differences requires in-depth knowledge of each tool and a lot of time.
At the end of the day, every tool somehow backs up your data. CLI interfaces, encryption algorithms, deduplication logic, supported backends, underlying programming languages and a lot more may differ. Identify what’s most important to you, test different solutions and then use the tool that works best for your use-case.
