The original message does not seem to have made it through, so here I try again. Von: Claudius Ellsel Gesendet: Donnerstag, 10. Dezember 2020 15:37 An: linux-btrfs@vger.kernel.org Betreff: How to properly setup for snapshots   Hello, I recently started setting up btrfs on Ubuntu 20.04 LTS for usage as an SMB share mainly. Currently I am at the stage that I have two disks set up with RAID1 and automatically mounting them on boot with a fstab entry. Also I have setup samba and have transferred data on it. Now I wanted to create snapshots, but am not sure how exactly that works. The wiki does not say much and information on the internet is not really reliable. The problem might be that I currently don't have any subvolumes set up at all. Am I still be able to create snapshots in this stage or do I have to create a subvolume first from which snapshots can be created afterwards? Also I learned about snapper from SUSE which sounds nice, but I don't want to break things while trying to use it. Unfortunately I am already at a somewhat production stage where I don't want to lose any data. Hopefully somebody can shed some light on this, maybe we can also add info to the wiki so there is a somewhat "official" source to rely on. PS: I am not subscribed to this list, hopefully replies will reach me anyway. Kind regards Claudius Ellsel
