Figuring out how to do db backups _can_ also be fairly time consuming.
There's a question of whether you want to spend time learning AWS or spend time learning your DB's hand-rolled backup options (on top of the question of whether learning AWS's thing even absolves you of understanding your DB's internals anyways!)
I do think there's value in "just" doing a thing instead of relying on the wrapper. Whether that's easier or not is super context and experience dependent, though.
Hmmm, I think you have to figure out how to do your database backups anyway as trying to get a restorable backup out of RDS to use on another provider seems to be a difficult task.
Backups that are stored with the same provider are good, providing the provider is reliable as a whole.
