snbackup 1.2.0

CLI tool to backup Supernote note files

Simple utility to backup notes from a Supernote device over WiFi

I created this cli tool to backup notes from my Supernote Nomad (A6 X2) over WiFi. No accounts or third party cloud service providers are necessary. It will probably work on any of the Supernote devices running the most up-to-date software.

Github repo for snbackup

The purpose is to download notes from a Supernote device and save them locally for backup and safe keeping. This is different than exporting notes as it does not attempt to convert notes to a different format. It's only meant to download the note files (with a .note extension) exactly as they are found on the device. If you are interested in converting your notes to PDF or PNG after downloading, see another project called supernote-tool.

It works by using the builtin Browse & Access feature available on the Supernote device. This feature creates a small web server directly on the device and makes it possible to browse its files through a web browser. The Supernote device and your computer must be on the same local network.

Steps:

1. Install Python 3.10 or newer along with pip

2. Setup your Python virtual environment and install with pip install snbackup

3. Create a folder on your computer to store your Supernote note backups

4. IMPORTANT: Create a file called ``` or edit the one provided with this project. This file is required to determine where to save your backups and where to access the device on the network. For example I place my config file in the same directory as my backups.

Example `:

{
    "save_dir": "/Users/devin/Documents/Supernote",
    "device_url": "http://192.168.1.105:8089/"
}

All note backups, metadata files, and logs for snbackup are located under the save_dir location.

Should work the same for Mac or PC. Use the forward slashes just like in the example above even on Windows.

The device_url needed will be displayed on the Supernote when Browse & Access is enabled. Use that URL from your device here.

5. Make sure the Supernote device is connected to WiFi with the Browse & Access feature turned on

6. There are two ways to run the command from your terminal or command line:

   • snbackup

     This will look for the ` in your current working directory

   • `snbackup -c /the/path/to/``

     This optionally specifies the location of the `

The first run may take a few minutes depending on how big your notes are and how many you have on the device. The first backup is a full backup, but subsequent runs only backup the notes that have been modified since the last backup; this greatly speeds up future backups.

You can also force a full backup of all notes by running snbackup -f or snbackup --full

The notes are stored as is under your local save directory setup in the config.json file. If a note called Ideas lives inside a folder called Stuff on your Supernote device, it will be stored locally as /Users/devin/Documents/Supernote/<YYYY-MM-DD>/Note/Stuff/Ideas.note or translated to C:\Users\devin\Documents\Supernote\<YYYY-MM-DD>\Note\Stuff\Ideas.note on Windows.

Future plans:

• Add a proper first time setup option
• Add archive or cleanup feature to remove old backups
• Persist note metadata in sqlite instead of json file
• Add note validation option to ensure local and remote notes are identical
• A restore device feature to bulk move local backups back to device
