The Snap Vault secondary system makes a snapshot of its own volume where the qtrees are located.

In every SnapVault update cycle, the destination (secondary) system automatically takes a read-only Snapshot copy of the volume that contains the replicated qtree(s). This Snapshot copy—whose name is derived from the Snapshot being transferred from the primary—serves two purposes:

1. It preserves a point-in-time, immutable backup on the secondary.

2. It becomes the baseline for the next incremental update.

Because the Snapshot is created on the secondary volume itself, the secondary system always “makes a snapshot of its own volume where the qtrees are located,” exactly as the statement describes.

Why the “False” option is wrong:

If the secondary did not create its own Snapshot copy, there would be no local, point-in-time image to satisfy retention policies or future incremental transfers. NetApp’s SnapVault architecture explicitly requires these secondary-side Snapshots; therefore denying their creation contradicts official product behavior.

“During a SnapVault update

the SnapVault secondary volume creates a Snapshot copy that corresponds to the primary Snapshot copy being transferred.”

” Section “SnapVault update

” step 2:

“The destination (secondary) system creates a new Snapshot copy of the destination volume before applying the incremental transfer.”

§4.3 “Snapshot copies on the secondary”:

“Each SnapVault update results in a new

locked Snapshot copy on the secondary volume that holds the protected qtrees. These copies are retained based on the configured retention schedule.”
