Restore from Backup

Backups are saved to /root/zabbix-backup-YYYYMMDD-HHMMSS/.

After a fresh install, restore from a backup (same Zabbix version only):

# Restore database
mysql -u zabbix -p zabbix < /root/zabbix-backup-YYYYMMDD-HHMMSS/database.sql

# Restore config (optional)
cp /root/zabbix-backup-YYYYMMDD-HHMMSS/zabbix/zabbix_server.conf /etc/zabbix/
systemctl restart zabbix-server

Schema changes between versions may cause issues - only restore to the same version.
