GitBackup — GitHub Repository Backup Desktop App

Skill by ara.so — Daily 2026 Skills collection.

GitBackup is an Electron + React desktop application that clones all your GitHub repositories locally and optionally uploads compressed .tar.gz archives to AWS S3 or Cloudflare R2. It supports incremental updates, scheduled backups, concurrent processing, and encrypted local settings storage.

Installation

Download Pre-built Binary

Download from Releases:

Platform	File
macOS	GitBackup-x.x.x.dmg
Windows	GitBackup-Setup-x.x.x.exe
Linux	GitBackup-x.x.x.AppImage

Prerequisite: Git must be installed and available in PATH.

Build from Source

git clone https://github.com/hiteshchoudhary/gitbackup.git
cd gitbackup
npm install

# Development with hot reload
npm run dev

# Package for current platform
npm run package

# Platform-specific builds
npm run package:mac
npm run package:win
npm run package:linux

GitHub Token Setup

1. Go to github.com/settings/tokens
2. Tokens (classic) → Generate new token (classic)
3. Select scopes: repo (full access) + read:org (for org repos)
4. Copy the token and paste into the app's Setup page

Fine-grained tokens also work — grant Repository access → All repositories.

Core Services — Code Examples

GitHub Service (Octokit)

// electron/services/github.service.ts
import { Octokit } from "@octokit/rest";

export class GitHubService {
  private octokit: Octokit;

  constructor(token: string) {
    this.octokit = new Octokit({ auth: token });
  }

  async getAuthenticatedUser() {
    const { data } = await this.octokit.users.getAuthenticated();
    return data;
  }

  // Fetch all repos with pagination — handles 200-300+ repos
  async fetchAllRepositories(filters: RepoFilters): Promise<Repository[]> {
    const repos: Repository[] = [];

    if (filters.owned) {
      for await (const response of this.octokit.paginate.iterator(
        this...,
        { : , :  }
      )) {
        repos.(...response.);
      }
    }

     (filters.) {
       orgs =  ...();
       ( org  orgs.) {
          ( response  ...(
          ...,
          { : org., :  }
        )) {
          repos.(...response.);
        }
      }
    }

     (filters.) {
        ( response  ...(
        ...,
        { :  }
      )) {
        repos.(...response.  );
      }
    }

Git Service (Clone & Fetch)

// electron/services/git.service.ts
import simpleGit, { SimpleGit } from "simple-git";
import path from "path";

export class GitService {
  // Clone with all branches or fetch updates if already exists
  async backupRepository(
    repoUrl: string,
    backupPath: string,
    token: string
  ): Promise<void> {
    // Embed token in URL (cleaned after operation)
    const authenticatedUrl = repoUrl.replace(
      "https://",
      `https://x-access-token:${token}@`
    );

    const repoExists = fs.existsSync(path.join(backupPath, ".git"));

    if (repoExists) {
      // Incremental update — only fetch changes
      const git: SimpleGit = simpleGit(backupPath);
      await git.fetch(["--all", "--prune"]);
    } else {
      // First run — full clone with all branches
      fs.mkdirSync(backupPath, { :  });
       :  = ();
       git.(authenticatedUrl, backupPath, []);
    }

    
     :  = (backupPath);

      : {
        : config.,
        : config.,
      },
    });
  }

   (: , : ): <> {

    const archivePath = path.join(outputPath, archiveName);

    await tar.create(
      { gzip: true, file: archivePath, cwd: path.dirname(sourceDir) },
      [path.basename(sourceDir)]
    );

    return archivePath;
  }
}

Backup Orchestrator (Pipeline)

// electron/services/backup-orchestrator.ts
import pLimit from "p-limit";

export interface BackupOptions {
  repos: Repository[];
  backupPath: string;
  token: string;
  concurrency: number;       // 1-10

            : (error  ).,
          });
        }
      })
    );

     .(tasks);
  }
}

Scheduler Service

// electron/services/scheduler.service.ts
import cron from "node-cron";

export type ScheduleFrequency = "daily" | "weekly" | "monthly";

export class SchedulerService {
  private task: cron.ScheduledTask | null = null;

  schedule(

}

Encrypted Settings Store

// electron/store/store.ts
import Store from "electron-store";

interface AppSettings {
  githubToken: string;
  backupPath: string;
  concurrency: number;
  schedule?: {
    enabled: boolean;

    endpoint?: string;
    accessKeyId: string;
    secretAccessKey: string;
  };
}

export const store = new Store<AppSettings>({
  encryptionKey: "your-app-encryption-key", // electron-store encrypts at rest
  defaults: {
    githubToken: "",
    backupPath: "",
    concurrency: 3,
  },
});

// Usage
store.set(, token);
store.();
store.(, {
  : ,
  : process..!,
  : process..!,
  : process..!,
  : process..!,
});

IPC Bridge (Preload → Renderer)

// electron/preload.ts
import { contextBridge, ipcRenderer } from "electron";

contextBridge.exposeInMainWorld("electronAPI", {
  // GitHub
  validateToken: (token: string) =>
    ipcRenderer.invoke("github:validate-token", token),
  fetchRepos: (filters: RepoFilters) =>
    ipcRenderer.invoke("github:fetch-repos", filters),

  // Backup
  startBackup: (options: BackupOptions) =>
    ipcRenderer.invoke("backup:start", options),
  onProgress: (callback: (data: ProgressEvent) => void) =>
    ipcRenderer.on("backup:progress", (_event, data) => callback(data)),

  // Settings
  getSettings: () => ipcRenderer.invoke("settings:get"),
  saveSettings: (settings: Partial<AppSettings>) =>
    ipcRenderer.invoke(, settings),

  
  :  ipcRenderer.(),
});

// src/hooks/useBackup.ts — React renderer side
import { useState } from "react";

export function useBackup() {
  const [progress, setProgress] = useState<Record<string, RepoStatus>>({});

  const startBackup = async (repos: Repository[]) => {
    // Listen for per-repo progress events
    window.electronAPI.onProgress((data) => {
      setProgress((prev) => ({
        ...prev,
        [data.repoName]: data.status,
      }));
    });

    await window.electronAPI.startBackup({
      repos,
      concurrency: 5,
    });
  };

  return { startBackup, progress };
}

Configuration Reference

Setting	Description	Default
githubToken	PAT with repo + read:org scopes	—
backupPath	Local directory for cloned repos	—
concurrency	Parallel repo operations (1–10)	3
schedule.frequency	daily / weekly / monthly	—
schedule.time	Time in HH:MM format	—
cloud.provider	s3 or r2	—
cloud.bucket	S3/R2 bucket name	—
cloud.region	AWS region (S3 only)	us-east-1
cloud.endpoint	Custom endpoint (R2: https://<id>.r2.cloudflarestorage.com)	—

Cloudflare R2 vs AWS S3 Configuration

// AWS S3
const s3Config: CloudConfig = {
  provider: "s3",
  bucket: process.env.S3_BUCKET!,
  region: process.env.AWS_REGION ?? "us-east-1",
  accessKeyId: process.env.AWS_ACCESS_KEY_ID!,
  secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY!,
};

// Cloudflare R2 — uses S3-compatible API
const r2Config: CloudConfig = {
  provider: "r2",
  bucket: process.env.R2_BUCKET!,
  endpoint: `https://${process.env.CF_ACCOUNT_ID}.r2.cloudflarestorage.com`,
  accessKeyId: process.env.R2_ACCESS_KEY_ID!,
  secretAccessKey: process.env.R2_SECRET_ACCESS_KEY!,
};

Repository Filters

interface RepoFilters {
  owned: boolean;          // Repos you own
  organizations: boolean;  // Repos in your orgs
  starred: boolean;        // Repos you've starred
  forked: boolean;         // Forked repos
  collaborator: boolean;   // Repos you collaborate on
}

// Example: back up only owned + org repos
const filters: RepoFilters = {
  owned: true,
  organizations: true,
  starred: false,
  forked: false,
  collaborator: false,
};

Common Patterns

Adding a New IPC Handler

// electron/ipc/backup.handler.ts
import { ipcMain } from "electron";
import { BackupOrchestrator } from "../services/backup-orchestrator";

export function registerBackupHandlers(mainWindow: BrowserWindow) {
  ipcMain.handle("backup:start", async (_event, options: BackupOptions) => {
    const orchestrator = new BackupOrchestrator();

    await orchestrator.run({
      ...options,
      onProgress: (repoName, status) => {
        // Send progress back to renderer
        mainWindow.webContents.send("backup:progress", { repoName, status });
      },
    });
  });
}

Adding a New Settings Page (React)

// src/pages/Settings.tsx
import { useEffect, useState } from "react";

export default function Settings() {
  const [settings, setSettings] = useState<AppSettings | null>(null);

  useEffect(() => {
    window.electronAPI.getSettings().then(setSettings);
  }, []);

  const handleSave = async () => {
    await window.electronAPI.saveSettings(settings!);
  };

  return (
    <div>
      <label>Concurrency (1-10)</label>
      <input
        type="number"
        min={1}
        max={10}
        value={settings?.concurrency ?? 3}
        onChange={(e) =>
          setSettings((s) => ({ ...s!, concurrency: Number(e.target.value) }))
        }
      />
      <button onClick={handleSave}>Save</>
    
  );
}

Troubleshooting

Issue	Fix
git: command not found	Install Git and ensure it's in system PATH
Token validation fails	Confirm repo + read:org scopes are granted
macOS "app can't be opened"	Right-click → Open to bypass Gatekeeper
Windows Defender warning	Click "More info" → "Run anyway"
Rate limit errors (large accounts)	Reduce concurrency to 1–2; app handles pagination automatically
R2 upload 403 errors	Verify CF_ACCOUNT_ID in endpoint URL and correct R2 API token permissions
Incremental fetch not working	Ensure backupPath still contains .git directory
Scheduled backup not triggering	Keep app running in system tray (don't fully quit)

Development Tips

# Run dev server (Vite + Electron with hot reload)
npm run dev

# Type-check without building
npx tsc --noEmit

# Build renderer only
npx vite build

# Inspect electron-store saved data location
# macOS: ~/Library/Application Support/GitBackup/config.json
# Windows: %APPDATA%\GitBackup\config.json
# Linux: ~/.config/GitBackup/config.json
