fridge-backup is a helper for creating and managing incremental backups with BTRFS snapshots. It implements the scheme described on Fedora Magazine.
Snapshots are created for the current day (systemd units are in contrib/) and are then copied to remote BTRFS drives as specified by the user. No encryption is added in, it's expected you'll encrypt the entire drive.
There's also no explicit restore support - just copy over the files you want to restore using your favorite file copying program.
$ sudo fridge-backup snapshot
Takes a snapshot of
/home and places it at
$ sudo fridge-backup sync /my/external/drive/
Copies the latest snapshots to your external drive. It will look to see if a previous snapshot exists on the external drive that can be used to create an incremental snapshot (and it will correctly use newly copied snapshots for incremental purposes if it makes sense to).
If configured (see below), you can specify a drive name instead of a path.
$ fridge-backup status
Lists available snapshots. It is expected that this will work without being run as root.
You can also run
fridge-backup help and
fridge-backup help [subcommand]
for more details on options.
A configuration file can be specified with
--config config.toml (before
the subcommand) or in the default location of
An example configuration looks like:
[backups] [backups.drive1] path = "/run/media/user/drive1/" [backups.drive2] path = "/run/media/user/drive2/"
This allows you to run
sudo fridge-backup sync drive1 instead of needing to
specify the path to where drive1 is mounted each time. Additionally, if the
path is available,
fridge-backup status will output information on which
snapshots are available in that backup.
Currently paths of
/home/ are hardcoded, this will become
configurable in the future.
At this time removal of old snapshots is a manual process. This too will be implemented in the future.
fridge-backup is a statically compiled Rust program and should work on recent
Linux distros without issue. You will need to have the
The list of Rust dependencies can be seen in Cargo.toml and by running
cargo tree. It is kept minimal on purpose as this program will usually
be run as root.
