BorgBackup (Borg) est un programme de sauvegarde par déduplication. Il supporte la compression et le chiffrement.

Borg permet de fournir un moyen efficace et sûr de sauvegarder des données.

Also, savvy web developers can use it to make friendlier sites–we’ll see some examples in the following sections.

You probably use prefers-color-scheme a lot within your CSS media queries, to make a dark or light theme for your sites and apps based on user preference. Maybe you also add a toggle so people can choose their color scheme, irrespective of their OS settings. Beautiful. But now there's more to play with!
