I have been trying to understand how snapshots work (in BRTFS and in general), but I still have some questions, and would appreciate if someone could clear them for me. To make things easier, I tried to make most of them Yes/No questions: 1. When creating the filesystem, I only made btrfs partition with no subvolumes. Do I have to use subvolumes, or can I snapshot entire “/“? 2. Can I take a snapshot of a working / root filesystem? 3. If I make a snapshot of / and there are some separate partitions mounted under /mnt/ or /home/, will snapshot skip them? 4. If I have a snapshot of /, can I completely erase this partition and later restore it in full form that snapshot, or do snapshots work only if a limited number of files has been changed? If the former, then does it mean that snapshot size will be comparable to the original data size? 5. Can a snapshot be stored on a different partition? And if so, does that partition have to be BTRFS too? I ask, because I would also want to store snapshots in a cloud storage.
