These exact commands (together with a save-all) are already issued, see here. Furthermore, an explicit $ sync is issued. My best guess is that save-all involves complications in addition to the mere saving and thus sync thus not catch them all, i.e. does not wait.
I am happy to incorporate any new ideas of how to rectify this situation but I am unfortunately not aware of a good solution. The only thing I can think of is incorporating a small delay between save-all and $ sync
When backing up a running server with minecraftd-backup, I noticed that the tar command had output "file changed as we read it". This suggests that files are being modified by the running server during the backup, and I'm a bit concerned that this would result in corruption when the backup is restored.
Would it be possible for the script to do save-off and save-all prior to doing the backup, and then do save-on afterward?
@Xarius
No, the backup logic should not have changed. Note, triggering new backups is purely a systemd thing and the configuration is exclusively handled by systemd timers. As long as you configure them in /etc and not in /usr/lib/ your changes will not be overridden by an update.
Did something change with how backups are handled recently? I had them set to be hourly, and they reverted to being daily after the last update. But, now when I try to enable the backup system service, it claims it doesn't exist? Highly likely I'm just forgetting something simple here.
@DragonX256
hmm I changed the login shell about a year ago to /bin/bash in the corresponding .sysusers file. The commit is from 3 October 2020 11:48 UTC+2 to be precise. However, I have to admit I forgot why I made this change.
You may safely edit /etc/passwd and adapt the shell. The sysusers entry should already be correct.
Well okay, I had to delete package and minecraft user and reinstall package again to let systemd correctly create user with proper uid and gid.
Issue is resolved to me...
Okay, it's definitely odd why minecraft user gets nologin shell on my installation. I'll will look into that deeply... Maybe I just need to delete user.
@edh I changed minecraft user shell from /usr/bin/nologin to /bin/bash and it started working...
@DragonX256 Please try to produce a minimal example e.g. in a clean container.
First of all please verify that the minecraft server starts if you execute the necessary java commands from within a shell as the minecraft user. Second, please validate that your tmux setup is working, i.e. that you can spawn a session as the minecraft user. If both work then the management script should also work.

To get an overview of the available options provided by the management script, be sure to have a look at the help page or read the according section on the ArchWiki article [1].
You can quit the console without shutting down the server by press ctrl+a d (first ctrl+a and after releasing the buttons press d; ctrl+b also works). This will detach your input from the server console. The attaching and detaching is done with tmux (previously GNU screen) since it lets you view and type into the console, send single commands to it and keep it alive without a connected user. Take a look at the the command overview at the ArchWiki [2] to get a feel for its power. (@carmelo12341)
