```
|
|
1. Edit each applicable unit file(s).
|
|
- Ensure paths are correct (ReadWriteDirectories, [WorkingDirectory](https://www.freedesktop.org/software/systemd/man/systemd.exec.html),
|
|
[ExecStart](https://www.freedesktop.org/software/systemd/man/systemd.service.html),
|
|
[ExecStop](https://www.freedesktop.org/software/systemd/man/systemd.service.html)).
|
|
- Ensure timers property "[OnUnitActiveSec](https://www.freedesktop.org/software/systemd/man/)" (backup interval) is set as
|
|
desired.
|
|
```console
|
|
$ nano minecraft-backup.service
|

```
|
|
1. Set file permissions.

1. Set file ownership and group.
|
|
```console
|
|
# chown root:root /etc/systemd/system/minecraft-*

|
|
1. Add user base upon "User" unit property value.
|
|
```
|
|
# useradd -r -s /bin/bash minecraft
|
|
```
|
|
```
|
|
-r create a system account.
|
|
-s user's login shell.
|
|
```
|
|
1. Add group based upon "Group" unit property value.
|
|
- **Note:** This step is only required if group name differs from username.
|
|
```
|
|
# groupadd minecraft
|
|
# usermod -a minecraft minecraft
|
|
```
|
|
```
|

-a add the user to supplementary group.

|
|
# systemctl enable minecraft-stats.timer
|
|
```
