Snapshots is not something Btrfs "quietly" makes on its own, snapshots are something *you* create. Snapshots of static and unmodified data are essentially free in terms of disk space (due to CoW only the changes from the point snapshot was taken and further on, will require additional space); and if you heavily modify your files and want to also keep a trail of snapshots, it's of course up to you to ensure you have enough disk space for that. -- With respect, Roman
