When it comes to backing up a Fedora Silverblue system, some of the traditional tools may not function as expected. BorgBackup (Borg) is an alternative available that can provide backup capability for your Silverblue based systems. This how-to explains the steps for using BorgBackup 1.1.8 as a layered package to back up Fedora Silverblue 29 system.
On a normal Fedora Workstation system, dnf is used to install a package. However, on Fedora Silverblue, rpm-ostree install is used to install new software. This is termed layering on the Silverblue system, since the core ostree is an immutable image and the rpm package is layered onto the core system during the install process resulting in a new local image with the layered package.
“BorgBackup (short: Borg) is a deduplicating backup program. Optionally, it supports compression and authenticated encryption.”

Additionally, the main way to interact with Borg is via the command line. Reading the Quick Start guide it becomes apparent that Borg is well suited to scripting. In fact, it is pretty much necessary to use some form of shell script when performing repeated thorough backup’s of a system. A basic script is provided in the Borg Quick Start guide , as a point to get started.
