timeshift

In this guide I will walk you through the installation procedure to get an Ubuntu 20.04 system with a luks-encrypted partition for the root filesystem (including /boot) formatted with btrfs that contains a subvolume @ for / and a subvolume @home for /home. I will show how to optimize the btrfs mount options and how to add a key-file to type the luks passphrase only once for GRUB. I will also cover how to setup an encrypted swap partition or swapfile. This layout enables one to use Timeshift and timeshift-autosnap-apt which will regularly take snapshots of the system and particularly on any apt operation. Moreover, using grub-btrfs all snapshots can be accessed and booted into from the GRUB menu.

In the following I will go through my post installation steps on Ubuntu, i.e. which settings I choose and which apps I install and use.

In this guide I will walk you through the installation procedure to get a Pop!_OS 20.04 system with a luks-encrypted partition which contains a LVM with a logical volume for the root filesystem that is formatted with btrfs and contains a subvolume @ for / and a subvolume @home for /home. The system is set up in a RAID1 managed by the btrfs filesystem. I will show how to optimize the btrfs mount options and how to setup encrypted swap partitions which work with hibernation. This layout enables one to use Timeshift and timeshift-autosnap-apt which will regularly take snapshots of the system and particularly on any apt operation. The recovery system of Pop!_OS is also installed to both disks and accessible via the systemd bootloaders. Due to the RAID1 managed by btrfs you get redundancy of your data.
