The data structures that are backed up and restored through SnapVault depend on the primary system.

On systems running Data ONTAP, the qtree is the basic unit of SnapVault backup and restore.

SnapVault backs up specified qtrees on the primary system to associated qtrees on the SnapVault secondary system. If necessary, data is restored from the secondary qtrees back to their associated primary qtrees.

On open systems storage platforms, the directory is the basic unit of SnapVault backup. SnapVault backs up specified directories from the native system to specified qtrees in the SnapVault secondary system.

If necessary SnapVault can restore an entire directory or a specified file to the open systems platform.

Answer : D

Add a new backup user to the Backup Operators useradmin group list. Enter the following command:

useradmin user add backupuser -g 'Backup Operators'

Generate an NDMP password for the new user. Enter the following command:

ndmpd password backupuser

The NDMP password is used to authenticate the NetBackup media server to the storage system. This password is required for setup on the NetBackup management station.

Answer : C, D, E

Section: Data Protection

NetApp also recommends that if deduplication is used on the source volume, then it should also be used on the destination volume. However, you are not restricted using deduplication on the source volume only.

The deduplication schedule is not tied to the qtree SnapMirror update. In other words, the deduplication process does not automatically start at the completion of the qtree SnapMirror transfer.

The fingerprint database and the change log files that are used in the deduplication process are located outside of the volume in the aggregate and are therefore not captured in Snapshot copies

Think of ndmpcopy as a sort of ftp for SAN. You can use it to copy files from one volume to another. Because the file is read from one volume and written to another, the constraints of volume types are not an issue.

Answer : D

Volume SnapMirror operates at the physical block level. It replicates the contents of an entire volume, including all Snapshot copies, plus all volume attributes verbatim from a source (primary) volume to a target (secondary) volume. Implicitly, the destination volume will be the same as the source volume. Since C is incorrect, A & B must be correct.

Qtree snapmirror operates at the logical level, so it is unimportant that the destination system has a different volume configuration.

ndmpcopy is similarly operating with data already read from the volume and so the destination volume type is not a consideration.
