Manual 7 of 8

Backup, LAN & Cloud

Protect business continuity without confusing backup tools with live shared retail concurrency.

What cloud continuity means

Cloud continuity is for backup snapshots, staged sync batches, and conflict-reviewed pulls. It is not the correct model for three live counters billing at the same time.

Use the right topology

Single PC

Use Local Desktop mode and keep regular backups.

Same-premise multi-PC

Use LAN Hub so one machine becomes the authoritative writer for invoices, stock, and payments.

Hosted / multi-location

Use Cloud Workspace when you need centralized hosted authority on the same model.

Backup and deployment topology guidance
Use continuity features for backup, restore, and staged sync. Do not market or operate them as live shared writes.
LAN Hub and Cloud Workspace exist to centralize invoice numbering, stock writes, and payment authority.
If multiple counters are live, authoritative topology is mandatory. Folder-sync is not a safe shortcut.
Annotated view: continuity protects recovery; authoritative topology protects correctness during concurrent billing.

Recommended continuity routine

  1. Keep local backups or export snapshots on a defined schedule.
  2. Use cloud continuity for continuity and restore planning, not for pretending one shared folder is a database server.
  3. For LAN Hub deployments, treat the host machine as critical infrastructure and protect its backup path.
  4. Test restore flows before relying on them operationally.

Operational warning

Do not use folder-sync or shared DB-copy workflows for simultaneous live billing across multiple PCs. Invoice number collisions and stock divergence are business risks, not theoretical edge cases.
