ISILON 's backup to TSM using NDMP three-way
Dear,
I need to configure a three-way NDMP backup of a ISILON (OneFS 8.0.x) to a TSM Server, but I didn't find any documentation about it. In the document "Dell EMC - Isilon OneFS Backup and Recovery Guide" only have information about how to configure a two-way NDMP backup with TSM Server (when there is a Backup Accelerator node in the cluster) and this is not our case.
I'll appreciate any help!
Regards,
Bruno

The first step is to start with another TSM NDMP client that is already properly configured. Basically, three-way NDMP is essentially sending data from the desired NAS to be backed up to another NAS that is directly-connected to TSM for backups. Typically, the directly-connected NAS is physically attached to tape resources, but that's not always the case.
The idea is, you want to configure the directly-connected NAS as the "data mover" in NDMP parlance: the NAS that moves block data to tape (TSM). IBM has documentation for TSM configuration,so I'd start there.
Let me know if that helps!

Firstly, thank you for your message!
In fact, I do not have any NAS that is directly attached to a library/tape drives.
I found some information from TSM documentation where the 3-way NDMP backup is also named as “filer-to-server”.
Below is figure about it.
“With the filer-to-server configuration, the library is attached to the DMA (Tivoli Storage Manager Server). The NAS device does not have access to the library, as shown in Figure. This configuration is also known as 3-way NDMP backup. The backup data from the NAS device is transferred over the network (TCP/IP) to the Tivoli Storage Manager server.”

Ahh - sorry - I missed an important, key detail. For the most part, you can follow the steps in the Isilon Backup and Recovery Guide for OneFS 8.0, but you won't be setting up any tape drives for a backup accelerator, since you don't have one. You'll need to use the drive definitions that already exist on the TSM server, as seen by the file-server you define in TSM.
Let us know if that helps!
