LND Node Backup Utility

About

This is a utility that runs as a daemon which allows for backuping up of a lightning node.

Usage

Configuring

You need to have a config file in $HOME/.lncm/nodebackup.toml

provider = "dropbox"
nodename = "testnode"
logfile = "/var/log/backup.log"
backupfile = "/root/.lnd/data/chain/bitcoin/mainnet/channel.backup"
pidfile = "/var/run/nodebackup.pid"

[apikeys]
dropbox = "APIKEYHERE"

Triggering channel backups (LND)

So you would like to see it work?

LNCM Install

docker exec -it compose_lnd_1 lncli exportchanbackup --all --output_file /root/.lnd/data/chain/bitcoin/mainnet/channel.backup

General LND Install

lncli exportchanbackup --all --output_file /root/.lnd/data/chain/bitcoin/mainnet/channel.backup

Installing

sudo /usr/bin/python3 -m pip install inotify
sudo /usr/bin/python3 -m pip install lndnodebackup

Running

After installing the utility simply invoke

lndnodebackup

This will run as a background task, which you can kill based on the PID.

Building

sudo python3 -m pip install setuptools wheel twine
python3 setup.py bdist_wheel
sudo pip3 install dist/nodebackup-X.X.X-py3-none-any.whl

Local testing

pip3 install dist/lndnodebackup-X.X.X-py3-none-any.whl
# Invoke after running
~/.local/bin/lndnodebackup start
# To stop, you can stop the PID with the normal kill signal

Distributing

python3 setup.py sdist bdist_wheel
# Test
python3 -m twine upload --repository-url https://test.pypi.org/legacy/ dist/*
# production
python3 -m twine upload dist/* 

Todo / What's Missing

• Support for Amazon S3
• Connect to LND and backup each channel individually and grab the text backup as well
• Robustness (maybe have the script handle SIGHUP to reload configuration file)
