The management scripts include a mechanism to create backups of the instances, i.e. instance configurations, logs and save folders. These backups are stored in the folder defined in /etc/7dtd.conf in the variable SDTD_BACKUP_ROOT. The backups will automatically be put in a new folder with the name being the current date and time. As the backups use ​hard links there will be no duplicated data, i.e. two consecutive backups will only take up additional disk space for the files that actually differ between the two. Still you can view any backup as being a whole backup.

To create a new backup just run

7dtd.sh backup

See Installation - Enable cron jobs for details on how to enable the automatic backup system.
