How To Extract a Folder from Duplicity Archive: Step-by-Step Guide

Ubuntu 7

Duplicity is a powerful tool that provides encrypted, digitally signed, versioned, and remote backup of files which can be restored at any time. One of its many features is the ability to extract specific folders from an archive. In this article, we will provide a step-by-step guide on how to extract a folder from a Duplicity archive.

Quick Answer

To extract a folder from a Duplicity archive, you can use the --file-to-restore option along with the appropriate time and date, source, and destination parameters in the Duplicity command. This allows you to restore the specific folder you want from the archive.

Understanding Duplicity

Before we dive into the steps, it’s important to understand what Duplicity is and what it offers. Duplicity backs up files by producing encrypted tar-format volumes and uploading them to a remote location. It uses librsync to record incremental changes, allowing for efficient storage of multiple versions of files. For more information on Duplicity, you can visit its official documentation here.

Extracting a Folder: The Basics

To extract a specific folder from a Duplicity archive, you’ll need to use the --file-to-restore option. This option allows you to specify the folder you wish to restore. You’ll also use the -t option to indicate the time and date from which to restore, and the destination to restore to.

Here is the basic syntax of the command:

duplicity -t <time> --file-to-restore <foldername> <source> <destination>

Let’s break down what each parameter does:

  • -t <time>: This specifies the time and date from which you want to restore. For example, -t 3D will restore files from 3 days ago.
  • --file-to-restore <foldername>: This specifies the name of the folder you want to restore. This can be a relative or absolute path.
  • <source>: This is the source of the Duplicity archive. This can be a local file path or a remote URL.
  • <destination>: This is the destination folder where you want to restore the files. This can be a local file path or a remote URL.

Step-by-Step Guide

Now that we understand the basics, let’s dive into a step-by-step guide on how to extract a folder from a Duplicity archive.

Step 1: Identify the Folder to Extract

First, you need to identify the folder you want to extract from the archive. This could be any folder that was included in the backup. For the purpose of this guide, let’s assume we want to extract a folder named logs from a backup taken 3 days ago.

Step 2: Run the Duplicity Command

Next, you’ll need to run the Duplicity command with the appropriate parameters. Here’s an example command:

duplicity -t 3D --file-to-restore logs file:///backup/location /destination/folder

In this example, -t 3D specifies that we want to restore files from 3 days ago. --file-to-restore logs specifies that we want to restore the logs folder. file:///backup/location is the source of the Duplicity archive, and /destination/folder is where we want to restore the files.

Step 3: Verify the Restoration

Finally, you should verify that the restoration was successful. You can do this by navigating to the destination folder and checking that the logs folder has been restored.

Conclusion

Extracting a specific folder from a Duplicity archive can be a complex task, but with the right understanding and steps, it can be done efficiently. Remember to always verify your restorations to ensure the process was successful. For more information on Duplicity and its features, you can refer to the official documentation.
