From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I have a server that has multiple services running under multiple users that each store data. I want to be able to bundle all this data up and send it to another server for backups.
At a high level, how do I manage permissions for this? Currently I run the backup as root, then chown it to a special backups user which can log in through ssh. But this all feels clunky to me.
I am somewhat in the same boat, but more gentoo sided. For the main repo they killed mkstage4 because its outdated and insecure. So like you i wanted to backup my data (my gentoo install) to my nas or local storage. Rsync is the magic bullet for this. You can use ssh to securley transfer data to or from the server. And it automate it via a cron job (i suggest fcron) for a automatic timed backup/sync. Now i will add, rysnc can be used as a backup. But as the name implies it syncs data from one pc to the other. So if you break your desktop and it syncs to your server. Your SOLPDQ, thats only if you automate it tho.
And for the services id reccomend making a directory and adding all the services to a group, which owns the directory. Or the more lazy solution, which is probably frowned uponed. But you can rsync your docker container data to a directory where it has permissions to copy/sync.
Id highly recommend Rsync tho and just syncing offsite to another computer
