Traffic view on Fiber Optics
ENVIRONMENT
Netbackup = 10.1.1
Netbackup OS = 2019
Robotic Tape Library Drives are connected with NDMP host and Netbackup Server thru Fiber Channel
QUERY
How we can see the FC Traffi...
Forum Discussion
Yes I mean FT.
The configuration what I see "Robot Control is attached to an NDMP host" means the backups should use a FT path directly between NDMP host and Tape Drives. However I see a traffic (when triggering backup policy) increase when I see the Task Manager of Windows where Netbackup is installed
Netbackup Server Ethernet has nothing to do. No need to increase the traffic on its own Ethernet. The backups should use a FT path directly between NDMP host and Tape Drives
Just want to see if there is any Netbackup command available which can show the backup path being followed by backup policy
Hello,
There is a confusion in at least 2 things:
Transport Type = FT is not used for every data movement over FC. It is used for a specialized transport where data between Client and Media Server are moved through SAN (= so called Fibre Transport protocol). Movements between Media Server and backup device are not reflected here, even if Media Server is identical with Client and there is no transport over LAN.
Robot Control Host is irrelevant for backup transport. It only defines a server/device which moves with robotic arm while loading/unloading media. Backup data flow can be in a different way and depends on a policy/schedule storage unit. When misconfigued, even data from this NDMP host can flow over LAN to the library drives.
There is no command which would display backup path for a policy on a low level. Just check policy storage unit and its definition, and where are client data. We see just a part of your NBU domain, not the whole context, so we cannot assess this.

So is this possible to use a Fiber Optic between NDMP and Robot Tape Library if all Netbackup/Robot TL and NDMP all are connected via Fiber Switch as well

Just for reference.
Hello,
generally yes. Check here if your NAS device supports "direct-attach" backup method:https://download.veritas.com/resources/content/live/OSVC/100046000/100046445/en_US/nbu_100_hcl.html?__gda__=1678342080_15d294d8415d9a3833963bb9761b5f6c#ndmp_devices-ndmp_devices_-_connection_methods.
Then please share policy storage unit properties.
(Policy Backup Selection and Robot Control settings are not relevant here).
