I've been on unmanaged MySQL for ~8 years now. Considered switching to managed but I'm not seeing any performance or stability issues, so I guess I'll just keep this train going until it craps out on me, then restore a backup onto a managed service, say sorry for the downtime, and that'll be that.
I get what your saying here, but its again the comparison with Github and extremely large sites thats the problem. Most of us dont run google/fb/github scale sites and the backup will probably fit on an external HDD and in some cases would be even downloadable over S3 in an hour.
That's what I can't be comfortable with : "would".
How long does it take to try it? A day?
Well then try it, either it'll work flawlessly on the first try, either you'll learn that the backup you have doesn't include logins, password and the security configuration that goes with it.
Or that the dump you took lost some data because it wasn't in the right encoding.
Or the tape drive you're using need specific drivers that aren't available on the web anymore because the company website's closed.
... This is a work of fiction. Any similarity to actual events might be purely coincidental...
