The following steps are involved in backing up NAS volume data using NDMP:

1.The DMA server creates a connection to the FluidFS cluster IP address.

NOTE: NDMP does not provide High Availability (HA). If a backup session is interrupted due to connection loss, the session is terminated.

2.The NDMP server on the FluidFS cluster creates a temporary snapshot of each NAS volume that the DMA server designated for backup. Alternatively, when performing a backup of replication target NAS volumes, the FluidFS cluster does not create a dedicated NDMP snapshot. Instead, it uses the base replica snapshot from the last successful replication.

Temporary NDMP snapshots are named using the following format: ndmp_backup_<session_ID>_<controller_number>

NOTE: Manually deleting the temporary snapshot will immediately terminate the current backup session. The error on the DMA application will be data unavailable or internal.

NOTE: If a backup session is terminated with an error, the temporary snapshot might remain, and can be safely deleted manually.

3.The NDMP server copies the NAS volume data to the DMA server.

4.After receiving the data, the DMA server moves the data to a storage device, such as a local disk or tape device.

5.Once the backup completes, the NDMP server deletes the temporary snapshots.

Supported DMAs

For the latest list of supported DMAs, see the Dell Fluid File System Version 3 Support Matrix. At the time of this writing, the FluidFS cluster supports the following DMAs:

CommVault Simpana 9.0

Quest NetVault Backup 8.6x and 9.0x

Symantec BackupExec 2010R3 and 2012

Symantec NetBackup 7.0

Symantec Protection Engine

IBM Tivoli Storage Manager 6.3

Configuring NDMP

Before you can take an NDMP backup, you must add a DMA server and configure the NDMP user name, password, and client port.

Adding a DMA Server

Configure one or more DMA servers from which the NDMP server can service NAS volume backup requests. There is no limit on the number of DMA servers taking backups at any point in time.

The DMA server must run a supported NDMP backup application.

The DMA server must be network accessible.
