Timeshift and BTRFS

Ask Fedora
1

Hello, I have installed Fedora Workstation with a BTRFS root partition and everything works pretty well… aside from timeshift. It tells me to select a partition with the root subvolume at @. How can I make this the case? I looked here however I can’t figure out how to set this up.

                                253:0    0 191.6G  0 crypt /home

Any and all help is appreciated! Everything else works great on my NVIDIA Optimus laptop!

Start the installation. Blivet will now allow you to put an @ in a btrfs subvolume name.
