How to use Deja Dup to backup to Amazon S3

Deja Dup Is a backup program that supports local and remote / cloud backup, which compresses and encrypts data. Most of the work is done by duplicityDeja Dup is a command line backup tool, with Deja Dup acting as a graphical wrapper. The application is tightly integrated with the GNOME desktop and officially supports Google Drive and Nextcloud as cloud backup storage locations. Cloud storage, Openstack Swift and Rackspace cloud file services. Backups of these cloud services have been marked as deprecated in Deja Dup, but there are currently no plans to drop support for them, and “they will continue to exist for the foreseeable future.” However, they are hidden by default.

If Deja Dup is not already installed (Deja Dup is installed by default in many GNOME Linux distributions), it should be available in the repository.
With Deja Dup installed but closed, it’s time to change the option available only to Dconf. This option unhides the Amazon S3 option from the Deja Dup storage location option. You can use the Dconf editor by navigating to /org/gnome/deja-dup And change backend The essential s3. This can also be done using the following command:

gsettings set org.gnome.DejaDup backend s3

Similarly, you can also use gcs For Google Cloud Storage, openstack For Openstack Swift, and rackspace Rackspace Cloud Files service. I personally just try to backup to Amazon S3 from these services.
Now launch Deja Dup (which may appear as “Backup” in the application menu) and select the folder to back up and the folder to ignore. Next, click Storage location On the sidebar, you will be able to choose Amazon S3 as the storage location.
To use your Amazon S3 account to authenticate Deja Dup, you need an access key ID and secret access key, which you can get from your Amazon AWS console: Sign in, click your name in the upper right corner of the screen, then click My Security CredentialsAnd then expand Access keys, Create a new access key here, and save the key ID and secret access key in a safe place.
Go back to Deja Dup (on the Storage Location tab) and enter the Amazon S3 access key ID:Deja Dup Amazon S3

You can now create your first backup with a single click Overview In the Deja Dup sidebar and click Back Up Now Button:

You will be prompted for your Amazon S3 secret access key, followed by an encrypted password, which is used to encrypt the backup. If you plan to schedule automatic backups, you need to check the “Remember” box on both the Amazon S3 secret access key and the encrypted password. Do you want Deja Dup to save the backup in an existing S3 bucket? There is also a hidden setting-use the Dconf editor and navigate to /org/gnome/deja-dup/s3/ And change bucket Key value for your bucket name. Use commands instead of Dconf Editor to do this by:

gsettings set org.gnome.DejaDup.S3 bucket ''

Do you want to reset the Deja Dup backend key to the default value (only officially supported cloud backup backends are shown, so after this, Amazon S3 will no longer be an option in Deja Dup)? You can use the Dconf editor to do the following: /org/gnome/deja-dupAnd then open Use default value Options backend Key, or use:

gsettings reset org.gnome.DejaDup backend
