Why each option
In Data ONTAP's snapshot rotation scheme, each newly created snapshot receives n=0 and all prior snapshots have their n incremented, so a higher n value means an older snapshot.
When Data ONTAP creates a new snapshot, the freshest copy is assigned n=0 and every existing snapshot in the series has its n value incremented by one. This means a snapshot with a higher value of n was created earlier and is therefore older than snapshots with lower n values in the same series.
A higher n value indicates an older snapshot, not a newer one - the most recently created snapshot always receives n=0.
The value of n reflects only chronological order and has no relationship to the operational importance of the snapshot.
Importance is not a concept associated with the n numbering scheme; the value solely indicates relative age within the snapshot rotation.
