file level backup direct to DD disk
Hello,
We have a 4 nodes which are part of cluster. Out of the 4 nodes(4 VMs), the one of the node is collecting all the data. Then that data is saved locally in a disk(Physical server) and that is backed up to DD disk.
Is it possible to run a script which can point to a Data Domain Pool to save instead of Local disk ?
Any example which of backup which can point to a Data Doman Pool to save directly ?

The core command for a standard file system backup is 'save'. If you want to start the backup (so-called manual backup) you simply specify
save -b pool object_to_save like in save -b Default /data
Now if you want to send the data to your DD you have 2 possibilities:
- Either define a new pool and label the DD volume appropriately.
- Label the DD volume to the same pool but unmount the other disks.
For automatic backups you better look at the 'workflow - visual representation' then select the pool, open the context-menu with a right-click on our mouse and select another pool.

@perumj1, What is the data that you are trying to store? Is it an application data like a DB, if yes see if you can find a networker module that supports said application. if not then you will need to create a backup dump in the local file system or some storage accessible to file system in order for the backup application to be able to pick it up.

or is your question about writing to a DD completely without using Networker? The question is so vague, that I don't understand what you are really asking?
If doing things outside of NW is required, and you don't want to simply write to a CIFS or NFS share, that you could create on a DD as well and mount that to any system supporting it, there is also the boostFS standalone application which offers accessing a DD via the boost protocol.
"Executive summary
Dell EMC Data Domain Boost - File System (BoostFS) provides a general file system interface to the DD Boost library, allowing standard backup applications to take advantage of DD Boost features.
The BoostFS Plug-In resides on the application system, presents a standard file system mount point to the application. With direct access to a BoostFS mount point, the application can leverage the storage and network efficiencies of the DD Boost protocol for backup and recovery. Only simple qualification is needed for the application to support BoostFS. The file system interface makes BoostFS easy to deploy, allowing it to be up and running in minutes."
I always prefer to have a backup application to be in control, so that one is aware of what data is in backup where?
But in this case I don't really get what you are even looking for as you are asking for scripting instead of having Networker schedule the backups (which is able to use pre/post command scripting on client end if so required)?
