Hi again,
In the configuration file you can find the files and directories for backup.
PLAYSMS_PATH="/var/www/html/playsms"
PLAYSMS_LIB="/var/lib/playsms"
PLAYSMS_BIN="/usr/local/bin"
PLAYSMS_LOG="/var/log/playsms"
You can backups this folders and run a “mysqldump” for the database.
Best Regards
Jaime
