Prerequisites

Note the following considerations for NDMP backups:

  • If the status of a disk object is offline, you cannot browse the disk in the management console or select it for backup.

  • The software operating on your NDMP storage system determines the maximum number of NDMP incremental backups of a specific path. For example, NetApp storage systems running supported versions of Data ONTAP support infinite incremental backups. Other appliances support eight true incremental backups of a given path; thereafter, incremental backups behave like DPX differential backups until the next base backup of that path. Consult your NDMP device vendor documentation for specific information on NDMP backup limitations.

  • File selection is only supported for NDMP nodes that are running NetApp Clustered Data ONTAP 8.3 or later. For other NDMP node types, you cannot select a descendant resource for exclusion in the source pane of the NDMP backup window.

Note. This capability requires that the NetApp cluster have vServer aware NDMP mode enabled and the following NetApp options also enabled:

>set advanced
>vserver services ndmp extensions modify -is-extension-0x2050-enabled true

  • On the source pane, a node expands to the directory/folder level. Underlying files may display but cannot be selected. For NDMP earlier than version 4, the level of expansion is more limited.

  • For NDMP appliances that do not support browsing beyond the volume level, such as nodes running NetApp Clustered Data ONTAP 8.2 or earlier, you can right-click on the volume name and use the Specify New Path option to manually enter the path to back up.

  • If you select multiple subdirectories as source objects, DPX backs up the entire common ancestor.

  • The NDMP device vendor may limit or restrict backup and recovery of certain files and folders. These limitations are inherently vendor-specific. Consult your NDMP vendor documentation for access limitations imposed on storage system objects.

  • NDMP backup cannot be used to directly protect the master server Catalog. The Catalog restore function does not support restoring data from NDMP archives.
