Administrator Guide

NOTE: NDMP has no load balancing built in. A single DMA backing up 10 NAS volumes from a single client VIP forces all 10
sessions on the same NAS controller. Therefore, use DNS round-robin to provide load balancing by specifying the DNS name
of the FluidFS cluster in the DMA.
• NDMP user name and password (default user name is backup_user)
• Port that the NDMP server monitors for incoming connections (default port is 10000)
(Optional) In addition, some DMA servers require more information, such as the host name of the FluidFS cluster, OS type, product name ,
and vendor name.
• Host name of the FluidFS cluster, which uses the following format:controller_number.FluidFS_cluster_name
• OS type – DellFluid File System
• Product – Compellent FS8600
• Vendor – Dell
Most backup applications automatically list the available NAS volumes to back up. Otherwise, you can manually type in the NAS volume
path. The FluidFS cluster exposes backup NAS volumes at the following path:
/NAS_volume_name
To improve data transfer speed, increase the number of concurrent backup jobs to more than one per NAS controller, distributing the load
across the available NAS controllers.
NDMP Exclude File Under Paths Using FluidFS
When you dene a backup using DMA, you can select specic directories from the virtual NAS volume to include in, or exclude from,
backup jobs.
Requirements
The following requirements must be met to include or exclude NDMP paths:
• The path specied can be a directory or a le. If the path is a directory, all child elements of that directory will be included in (or
excluded from) the backup.
Each path specied is a child of the backup root directory and must start with a forward slash (/).
• The maximum number of paths that you can include or exclude is 32.
• Each path can be a maximum of 128 bytes long.
• The rst or the last element of the path can contain a wildcard character (*).
• If both include and exclude paths are dened, the NDMP server will rst check for include, then check for exclude.
1 In the Storage view, select a FluidFS cluster.
2 Click the File System tab.
3 In the File System view, expand NAS Volumes and select a NAS volume.
4 Click Edit Settings.
The Edit NAS Volume Settings dialog box opens.
5 Select Data Protection.
6 Select or clear the NDMP Exclude Files Under Paths checkbox.
7 Specify a path to exclude and click Add.
NDMP Exclude Files Matching the Patterns Using FluidFS
Conguring DMA clients with data-exclusion patterns might not work with a few backup vendors such as BackupExec and Netbackup.
FluidFS has an option for handling exclude paths and patterns, which will be skipped when executing NDMP backup on the NAS volume.
This option can be congured at the NAS volume level, and is available under NAS Volume Settings.
