Backups

Linkding stores all data in the application's data folder. The full path to that folder in the Docker container is /etc/linkding/data. As described in the installation docs, you should mount the /etc/linkding/data folder to a folder on your host system.

The data folder contains the following contents that are relevant for backups:

  • db.sqlite3 - the SQLite database
  • assets - folder that contains HTML snapshots of bookmarks
  • favicons - folder that contains downloaded favicons

The following sections explain how to back up the individual contents.

Full backup

linkding provides a CLI command to create a full backup of the data folder. This creates a zip file that contains backups of the database, assets, and favicons.

Note

This method assumes that you are using the default SQLite database. If you are using a different database, such as Postgres, you'll have to back up the database and other contents of the data folder manually.

To create a full backup, execute the following command:

docker exec -it linkding python manage.py full_backup /etc/linkding/data/backup.zip

This creates a backup.zip file in the Docker container under /etc/linkding/data.

To copy the backup file to your host system, execute the following command:

docker cp linkding:/etc/linkding/data/backup.zip backup.zip

This copies the backup file from the Docker container to the current folder on your host system. Now you can move that file to your backup location.

To restore a backup:

  • Extract the zip file in a folder of your new installation.
  • Rename the extracted folder to data.
  • When starting the Docker container, mount that folder to /etc/linkding/data as explained in the README.
  • Then start the Docker container.

Alternative backup methods

If you can't use the full backup method, this section describes alternatives how to back up the individual contents of the data folder.

SQLite database backup

linkding includes a CLI command for creating a backup copy of the database.

Warning

While the SQLite database is just a single file, it is not recommended to just copy that file. This method is not transaction safe and may result in a corrupted database. Use one of the backup methods described below.

Warning

This method is deprecated and may be removed in the future. Please use the full backup method described above.

To create a backup, execute the following command:

docker exec -it linkding python manage.py backup /etc/linkding/data/backup.sqlite3

This creates a backup.sqlite3 file in the Docker container under /etc/linkding/data.

To copy the backup file to your host system, execute the following command:

docker cp linkding:/etc/linkding/data/backup.sqlite3 backup.sqlite3

This copies the backup file from the Docker container to the current folder on your host system. Now you can move that file to your backup location.

To restore the backup, just copy the backup file to the data folder of your new installation and rename it to db.sqlite3. Then start the Docker container.

SQLite database SQL dump

Requires SQLite to be installed on your host system.

With this method you create a plain text file with the SQL statements to recreate the SQLite database. To create a backup, execute the following command in the data folder on your host system:

sqlite3 db.sqlite3 .dump > backup.sql

This creates a backup.sql which you can copy to your backup location. As this is a plain text file you can also commit it to any revision management system, like git. Using git, you can commit the changes, followed by a git push to a remote repository.

Exporting bookmarks from the UI

This is the least technical option to back up bookmarks, but has several limitations:

  • It does not export user profiles.
  • It only exports your own bookmarks, not those of other users.
  • It does not export URLs of snapshots on the Internet Archive Wayback machine.
  • It does not export HTML snapshots of bookmarks. Even if you backup and restore the assets folder, the bookmarks will not be linked to the snapshots anymore.
  • It does not export favicons.

Only use this method if you are fine with the above limitations.

To export bookmarks from the UI, open the general settings. In the Export section, click on the Download button to download an HTML file containing all your bookmarks. Then move that file to your backup location.

To restore bookmarks, open the general settings on your new installation. In the Import section, click on the Choose file button to select the HTML file you downloaded before. Then click on the Import button to import the bookmarks.

Assets

If you are using the HTML snapshots feature, you should also do backups of the assets folder. It contains the HTML snapshots files of your bookmarks which are referenced from the database.

To back up the assets, then you have to copy the assets folder to your backup location.

To restore the assets, copy the assets folder back to the data folder of your new installation.

Favicons

Doing a backup of the icons is optional, as they can be downloaded again.

If you choose not to back up the icons, you can just restore the database and then click the Refresh Favicons button in the general settings. This will download all missing icons again.

If you want to back up the icons, then you have to copy the favicons folder to your backup location.

To restore the icons, copy the favicons folder back to the data folder of your new installation.
