Private File Saver - Desktop client to sync local files to AWS S3 buckets

What is Private File Saver?

It is a cross-platform desktop app that sync local files to your private AWS S3 bucket. AWS S3 is commercial-use cloud storage (object store) that provides end-to-end encryption, makes data stored inaccessible to cloud providers.

Features:

  • Sync local files to AWS S3 bucket
  • No installation required! Download and run, that's it.
  • Easy setup, with 3 simple steps
  • Able to detected file changes since last synced

Supported platforms:

  • Linux (Tested on Debian-based systems and Manjaro)
  • MacOS (Not done yet, help wanted)
  • Windows (Not done yet, help wanted)

Why Private File Saver?

Private File Saver is not a cloud storage service, it is merely a tool that helps synchronising local files to AWS S3 buckets. I personally don't trust conventional consumer cloud storage as much. I prefer storage solution with more granular control (encryption, access control, etc).

Secure with encryption at rest and on transmit

With AWS S3, all files can be encrypted from end-to-end, making sure that your files are not accessible by any parties other than yourself.

Highly durable

Files (objects) stored in S3 buckets are automatically replicated into multiple facilities in an AWS region. AWS ensures 11-9s for its data durability over a given year.

Setup Guide

Prerequisite:

  • You will need an active AWS account
  1. Download the executable
  2. Double click it
  3. Follow the initialization steps on the screen

For Developers

Application Architecture

Private File Saver is built using PyWebView + Vue.js, packaged with PyInstaller.

The core logic is implemented in Python, while the presentation layer is in Vue.js, glued with PyWebView.

Implementation Details

How files are compared?

Use md5sum: Private File Saver generates md5sum for all files and added it as metadata to the s3 object. The core logic compares md5sum from local files and remotely to determine if local file has changed.

You can’t perform that action at this time.
