SnapVault backup of a clustered Data ONTAP 8.2 or later system is done at what data set level?
The correct answer is C. FlexVol. In clustered ONTAP 8.2 and later, SnapVault backup relationships are defined at the FlexVol volume level, replacing the qtree-level granularity used in 7-mode.

Why each option
In clustered ONTAP 8.2 and later, SnapVault backup relationships are defined at the FlexVol volume level, replacing the qtree-level granularity used in 7-mode.
Aggregates are physical disk groupings that serve as containers for volumes; SnapVault does not create backup relationships at the aggregate level.
Directory-level granularity is not a supported SnapVault backup data set unit in ONTAP - SnapVault operates on volume-level Snapshot copies.
Clustered ONTAP 8.2 shifted the SnapVault backup unit from individual qtrees (the 7-mode model) to entire FlexVol volumes, meaning a SnapVault relationship is established between a source FlexVol and a destination FlexVol on the vault destination cluster or Vserver.
Qtree-level SnapVault was available in 7-mode ONTAP, but this model was replaced in clustered ONTAP 8.2 and later where the FlexVol is the backup unit.
