, there is no other sources for installation like debain packages or something.
If you have skills and time, you can make
1) OS images with pre-installed Vesta
3) docker images (there is ready solutions in Internet)
and your sense of unsafety will be satisfied.
If, only if, vestacp.com terminated, but it's very unlikely, github will be live.
But if you have so many if, then backup all and all software ;-)

It's not impossible mission, pal, you can restore backup on other cp if you write parser (script) to those cp as our users do for other CP like DirectAdmin, Cpanel, CWP and etc.
