Using AWS PrivateLink and NetBackup MSDP-C

Level 4

Hi Friends,

I recently wrote a blog about the AWS PrivateLink and NetBackup deployment guide that I released and wanted to give you a closer look on how to use the NetBackup Media Server Deduplication Storage Pool Cloud Tiering (MSDP-C) to use as a backup repository with your AWS PrivateLink.

What I want to focus on in this blog is AWS PrivateLink and NetBackup MSDP-C.   

How does MSDP work?  The backup client sends the backup image to a media server, which hosts the plug-in that deduplicates the backup data. The deduplication plug-in breaks the backup image into segments and compares the segments to all of the segments that are stored in that deduplication node. The plug-in then sends only the unique segments to the NetBackup Deduplication Engine on the storage server. The Deduplication Engine writes the data to a Media Server Deduplication Pool.

Once you’ve set up your PrivateLink in AWS, it’s now time to connect to the S3 storage with MSDP-C.

To connect to the newly created AWS PrivateLink, log into the NetBackup Primary server and navigate to Storage > Storage Configuration.  An MSDP Storage Server will need to be added or an existing one can be used.  This document assumes one has already been created.



  1. From Storage Configuration, click on Disk Pools and +Add to create a new Disk Pool and Volume.



  1. Select the MSDP server that will be used and give the new Disk Pool a name.  Click Next to continue.



  1. Next click on Add volume.



  1. Add Volume Part 1.
    • Give The volume a name.
    • Click on Cloud Storage Provider.



  1. Add Volume Part 2.
    • Click on Amazon and click select.


  1. Add Volume Part 3.
    • Give the region a name.
    • Enter the Location Constraint.
    • Add the Service URL which is the DNS name given by AWS under Endpoints with the prefix “bucket.” attached.
    • Change or keep the defaults for HTTP/HTTPS ports.
    • Click on Add.



  1. Add Volume Part 4.
    • Select the newly created Region.
    • Enter in the AWS Access Credentials and Secret Access Key.



  1. Add Volume Part 5.
    • Select if you would like to change any of the default security settings.



  1. Add Volume Part 6.
    • Choose Select or create a cloud bucket.
    • Click on Retrieve List to connect to AWS.



  1. Add Volume Part 7.
    • After connecting to AWS, either select a pre-created bucket or click on the +Add button to create a new bucket.
    • Click Next to continue.


  1. Add volume Part 8.
    • Add any replication targets if required.



  1. Add Volume Part 9.
    • Review what will be created and click Finish.



  1. The Disk Pool has been created and the next step is to add a Storage Unit so backups can use the new AWS PrivateLink.



  1. Click on the Storage Units tab and click on +Add.



  1. Select MSDP and click Start.



  1. Name the MSDP Storage Unit and click on Next.



  1. Select the disk pool recently created.


  1. Select Media Server you’d like to use.
  2. When the desired selections have been made, click on Save.
  3. The storage configuration is complete, and the new media can be used to perform backups.

With Veritas NetBackup MSDP-C and AWS PrivateLink, users can now safely transfer de-duplicated data to and from the AWS cloud without the risk of exposing sensitive data to visibility, tampering or theft.  Users you can now access S3 directly as a private endpoint using a secure, virtual network which leverages a new interface endpoint within your Virtual Private Cloud (VPC).
