What is the best way to backup configuration files across multiple servers?

Question

Backup

Gentlemen, give me an idea - what is the best way to backup periodically certain configs on 10 servers (linux)? So far, only the idea comes to mind to write one big script that will run copying them to the ball (you can scp, of course, but too lazy to fiddle with the
keys ) copy the specified configs to the ball

Answer 1

Also look into rsnapshot, which does just as many copies as you need (every hour, every day, keep xx copies, etc). It is available in standard repositories for almost all Linux and has been used for a long time.
True, in theory, it needs a local path, but this is solved through, well, for example, nfs mount.

Answer 2

I'm leaning towards my script. In your own, you can prescribe paths for any OS, for any configs.
You can collect together in a convenient way (ssh, cloud, email)

Answer 3

inside the network - bash using cron: (s)ftp
externally - bash using cron: sftp - only!
