Crumbs

Crumbs is a Proxmox Backup Server client for GNOME desktops. It is intended for immutable Linux desktops where the OS can be replaced or rolled and you just need to be selective about backing up user data.

Installation

You can install it by first adding this repo:

flatpak remote-add --user networkoctopus https://networkoctopus.github.io/flatpak/networkoctopus.flatpakrepo

then search for it in GNOME software.

or install manually:

flatpak install --user networkoctopus io.github.networkoctopus.Crumbs

Development

Test the core without GTK:

cargo test --no-default-features

Run the app on a system with GTK4 and libadwaita development packages:

cargo run

The Flatpak manifest builds both Crumbs and Proxmox Backup Client from pinned source revisions. The GitHub Actions workflow builds native x86_64 and aarch64 variants from the same manifest and combines them into one Flatpak repository. The development manifest temporarily permits Cargo network access.

The provisional application ID is io.github.networkoctopus.Crumbs. No project licence has been selected yet.

Licensing

Crumbs builds and bundles proxmox-backup-client as a separate executable in the Flatpak. That component is distributed under the GNU Affero General Public License version 3 by Proxmox. See THIRD_PARTY_NOTICES.md for pinned source revisions, the build patch, and license notices.
