2 Upgrades and Data Security
Version Upgrades
The software ships pre-installed; users mostly deal with version upgrades. The version and method follow the manufacturer's or delivery party's instructions — no self-deployment involved.
Recommended upgrade flow:
- Run "Back up now" under "System Settings" before upgrading and download the latest backup;
- Record the current version and business information to keep;
- Upgrade following the manufacturer's instructions;
- After upgrading, log in and verify warehouses, materials, stock, accounts, alerts and backup configuration;
- If anything looks wrong afterwards, keep the backup and site information and contact the manufacturer.
Pre-upgrade backup is mandatory; whether data is kept and settings change is defined by the upgrade notes. Never replace program files or touch system directories on your own — it jeopardizes future upgrades and data safety.
Data and Access Security
- Business data stays on the device with no public-cloud dependency; the actual reach is decided by the enterprise network and firewall policy.
- Download backups regularly to another device or offline storage and spot-check restores, so a device failure never means data loss.
- Set a strong administrator password and assign regular users by post and duty.
- Restrict access sources with the firewall; use a VPN or reverse proxy for external access instead of exposing the service port.
- Delete accounts of departing staff promptly and review last-login times regularly.
- No weak passwords on shared networks, and never share one account among several people.
