Question
SnapVault backup of a clustered Data ONTAP 8.2 or later system is done at what data set level?
Options
- AAggregate
- BDirectory
- CFlexVol
- DQtree
Explanation
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.
Common mistakes.
- A. Aggregates are physical disk groupings that serve as containers for volumes; SnapVault does not create backup relationships at the aggregate level.
- B. Directory-level granularity is not a supported SnapVault backup data set unit in ONTAP - SnapVault operates on volume-level Snapshot copies.
- D. 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.
