Add up your downtime over a three year period by relying on Git (or gmail, or AWS) versus the cost of trying to engineer some local-backup system, and the downtime associated with that going awry.
Outages happens - as long as we're talking hours a year, pretty much everyone but life-safety systems, critical infrastructure, and payment/high-traffic commerce sites are probably better off just letting third-party cloud vendors manage their systems. Take the downtime and relax.
(Now, if downtime consistently gets into the 10s of hours/year, it's time to look for a new cloud provider. )
