Teltonika Backup Builder

Windows desktop tool (C# + WPF, MVVM) for working with Teltonika backup files (.tar.gz), focused on TRB/RUT style devices.

It provides two modes:

1. Backup duplicate mode
   Create multiple backup copies from one source backup and set devicename + hostname in /etc/config/system to custom values.
2. REST API rebuild mode
   Analyze a source backup, generate a list of REST API calls, run them step-by-step or all at once, then generate and compare a resulting router backup.

---

Features

1) Backup duplicate mode

• Select one source backup (.tar.gz).
• Enter multiple hostnames (one per line, or comma/semicolon separated).
• For each hostname, create a new backup file:
  • File name is adjusted to include the target hostname.
  • In /etc/config/system, option devicename and option hostname are set to that hostname.
• Optional verification after generation.

2) REST API rebuild mode

• Analyze selected backup and extract /etc/config/* files.
• Build a planned API call list (visible in UI).
• Show full request preview for the selected call.
• Execute:
  • single selected call, or
  • all calls sequentially.
• After execution:
  • generate a new backup on the router via API,
  • download it,
  • compare /etc/config between original and API-result backup.
• Connection fields:
  • Router IP/URL (default 192.168.2.1),
  • username (default admin),
  • password.

Requirements

• Windows
• .NET SDK 10.0+

Build and run

dotnet build .\TeltonikaBackupBuilder.slnx
dotnet run --project .\TeltonikaBackupBuilder.App

---

API behavior (important)

• The app uses REST endpoints for rebuild mode (no shell command execution).
• Planned calls include config updates and backup actions (generate/download).
• Router HTTPS certificates are currently accepted without strict validation in the client (development convenience).

---

Limitations / notes

• API coverage depends on firmware/device endpoint compatibility.
• Some complex config areas may require endpoint-specific handling depending on router model/firmware.
• Always test on non-production devices first.
