General FAQ for NDMP

Are backups and restores LAN-free?

Backups and restores using a library attached to a file server will be LAN-free. However, backup and restore operations using using a library attached to a MediaAgent will not be LAN-free.

Can I browse for content on all subclients?

No. You can browse for subclient content only on NetApp 7-Mode, NetApp C-Mode, and Isilon clients. For vendor-specific information about adding subclient content, see Guidelines for Adding Subclient Content.

Can I enable the Image Backup Set option on a SnapVault copy?

Yes, you can enable the Image Backup Set option (for SnapMirror to Tape) on a backup set containing the SnapVault copy. However, for 7-Mode file servers the image backup of the SnapVault copy will not exactly match the primary (source) volume. For example, the non-qtree data on the primary volume will be in a qtree on the SnapVault copy; the SnapVault copy may also contain data from other primary volumes.

Is SnapMirror to tape (SMTape) supported for Cluster-Mode?

SMTape is only supported for Cluster-Mode NetApp arrays running ONTAP 8.3 or later. The array must also belong to a Commvault version 10 CommCell updated to SP9 or later.

What are some of the operations that the MediaAgent allows me to perform?

The MediaAgent software allows you to perform the following operations with the NDMP data:

  • Back up data from file servers to a library attached to a MediaAgent

  • Perform auxiliary copy operations to a library attached to a MediaAgent.

  • Perform deduplication, encryption and compression operations.

  • Use a drive pool configured to a MediaAgent as a backup destination. The MediaAgent allows that any storage policy configured to use a drive pool can be selected as a backup destination.

What is Tape Silvering?

Tape silvering is the process of shipping a physical copy of the source data to a destination site. This is useful for large file systems as it saves time and resources and also avoids transferring the file system over the network. Refer to the EMC Celerra documentation for more information.
