Download Aegis Backup

Linux Installation

Aegis Backup for Linux is available as a standalone Debian/Ubuntu (.deb) package, or as a Snap package across all major distributions. Both include the restic backup engine.

Step 1: Install the App

Option 1: Debian / Ubuntu (.deb) — recommended

1. Download the .deb package using the button above, then open your terminal.

2. Navigate to your Downloads folder:

3. Install the package using apt:

Note: using sudo apt install will automatically pull in any required system dependencies. The package bundles its own Python environment and restic.

Option 2: Snap Package

The Beta is on the Snap Store's candidate channel. Install it from the Snap Store or in your terminal:

To back up to USB drives and detect them when they are plugged in, also run these once:

Step 2: Run the Setup Wizard

Launch Aegis Backup from your applications menu. After you accept the terms, the first-run wizard sets everything up in four steps: pick the folders to protect (usually your home folder), accept the default classes, add a first USB drive or NAS share, and set a passphrase.

The passphrase is optional but recommended: it encrypts every backup, so a lost drive exposes nothing. Print the recovery sheet the wizard offers and keep it somewhere safe — if you lose both the passphrase and the sheet, nobody can open the backups, including us.

Step 3: Keep Backups Running

Until you install the background service, scheduled backups only run while the window is open. In the app choose Configure → Background service → Install. It runs as your own user, never as root.

Then add a second destination on a different device, and keep one copy away from home — a drive you rotate, or a friend's computer. Needs attention on the Overview tells you while either is missing. See the documentation for plans, other computers and restoring.

Settings, the catalog and logs are stored in ~/.aegisbackup/ (with the Snap: ~/snap/aegisbackup/current/.aegisbackup/) and are kept when the package is removed or updated.
