backup-root-to-btrfs

Small project consisting of a bash script rsyncing whole linux filesystem to a btrfs storage.

How to install

Link backup.sh to executable path

ln -s PROJECT_FOLDER/backup-root-to-btrfs /usr/bin/backup-root-to-btrfs

(Optional) Have a notification on each time USB disk is plugged in

This is a simple approach consisting of

• A C piece of code showing a notification and launching the backup script.
• A systemd unit description to launch the notification with correct path.

Compiling and installing notification program

$ g++ main.c -o backup-root-to-btrfs-notify $(pkg-config --cflags --libs libnotify) $ sudo ln -s PROJECT_FOLDER/backup-root-to-btrfs-notify/backup-root-to-btrfs-notify /usr/bin/backup-root-to-btrfs-notify

Install systemd unit

In file PROJECT_FOLDER/systemd/backup-root-on-usb-plugged.service. Replace MOUNT-TARGET.mount with systemd actual mount target you want to. You can retrieve the mount target by plugging in your USB device and type:

systemctl list-units -t mount

Then: $ sudo ln -s PROJECT_FOLDER/systemd/backup-root-on-usb-plugged.service /etc/systemd/user/

Finally: $ systemd --user start backup-root-on-usb-plugged.service $ systemd --user enable backup-root-on-usb-plugged.service
