On the contrary, my intention is to make snapshots of the OS (btrfs) and my idea is to store the snapshots on the /home nvme drive (ext4).
I don’t know if that’s the standard practice or if I’m over complicating things. My SSD is only 240Gb (I think) while my nvme is a 1Tb drive, thus the intention to store snapshots on the nvme. Maybe the 240Gb is sufficient for say a month’s worth of snapshots plus the OS?
