Snapshots also have the neat property of not being the full size of your corpus unless you are always major compacting, because they are hard links. This can be confusing if you use "du" to check the sizes of your snapshots to see if they're consistent, because du only counts disk usage the first time it sees a hard link. It is somewhat counter-intuitive that snapshots effectively get larger over time as they become the only copy of that version of the sstable on disk, when the "original" sstable is deleted via compaction. =Rob
