Back up the notes you’ve saved to Pinboard.
If you’re using Homebrew, you can just run
brew install pinboard-notes-backup
If you’re using the Nix package manager, run
nix-env -i -A nixpkgs.pinboard-notes-backup
If you use NixOS, run
nix-env -i -A nixos.pinboard-notes-backup

Building from source
This is a Haskell program that you can build using Stack. With Stack installed, just type
to download and install GHC (the Haskell compiler) and then
to build the
pnbackup binary and install it. (The default installation directory is
~/.local/bin; pass an argument like
--local-bin-path=/usr/local/bin to change this.)
You can also build the project with cabal-install, but I’m less familiar with that approach.
This project uses GitHub Actions for automated building. The build is checked on the latest versions of macOS and Ubuntu Linux, with various combinations of Stack, cabal-install, and GHC 8.6.x, 8.8.x, 8.10.x, and 9.0.x. The project does not currently build under GHC 9.2.x because of a temporary incompatibility between req and that GHC version.
First you’ll need to grab your Pinboard API token from Pinboard’s password settings page. It’s a string like “maciej:abc123456”.
To save your notes to a file called “Notes.sqlite”, run
pnbackup -t maciej:abc123456 Notes.sqlite
replacing the example API token with your own. This will put all of your notes into a SQLite database called “Notes.sqlite”.
Each time you run the program, it will fetch the list of your notes from the Pinboard server. It will then download any notes that are new or that have been updated on the server, and it will delete any notes that have been deleted from the server. The program does one-way synchronization only: it will update your local database to match what’s on the server but it will never make any changes on the server.
The Pinboard API requires a three-second wait time between each request, and the text of each note must be downloaded in a separate request, so the initial download of your notes may take a while. Subsequent syncs will generally be much shorter, depending on how often you add or modify notes and how often you run pnbackup. If you want to see exactly what
pnbackup is doing as it works, pass it the
Your notes are stored in a table called “notes” with the following schema:
CREATE TABLE notes (
id TEXT NOT NULL UNIQUE,
title TEXT NOT NULL,
text TEXT NOT NULL,
hash TEXT NOT NULL,
created DATETIME NOT NULL,
updated DATETIME NOT NULL
These columns correspond exactly to the fields listed on the Pinboard API page.
Why SQLite and not some plain-text format? In the words of Paul Ford,
SQLite is incredibly well-documented. It’s also instantly usable as a database from the command line with no pre-processing at all, even for very large files, and there are immediately usable SQLite APIs for every programming language. Plus it’s incredibly easy to turn SQLite data into plain text, it has freely available extensions for geo, full-text, and hierarchical data, and it’s tiny and public-domain.
If you've used this application to back up your notes to a file called Notes.sqlite, you could use this quick and dirty Python script to print them in JSON format:
from json import dumps
conn = sqlite3.connect("Notes.sqlite")
conn.row_factory = sqlite3.Row
curs = conn.cursor()
curs.execute("SELECT * FROM notes")
print(dumps([dict(r) for r in curs.fetchall()]))
