have you done a sudo apt install btrfs-progs ?

I also have some guides and videos for btrfs on popos, if you are interested: https://mutschler.eu/linux/install-guides/

It's a popOS installer problem, by default it doesn't create any subvolumes. To create snapshots with Btrfs you need to create subvolumes. To create and manage snapshots with Timeshift, it requires subvolumes "/@" and "/@home" on the top level. I have presented a bug on the popOS installer, to date unanswered: https://github.com/pop-os/distinst/issues/221

Makes sense.

PopOS uses Systemd-boot for managing boot. Timeshift only supports GRUB.

tuxedlinux commented 4 years ago

@teejee2008 makes sense. So that means you can't use Timeshift on Pop OS?

I am using Timeshift just fine on POP! I use a "trick" regarding systemd boot instead of grub, in the sense that I am rsyncing the efi partition into @ so I can restore it easily when needed. I use timeshift-autosnap-apt for this. I've outlined everything in the link I shared above.
