What is Veritas MSDP?
A storage server is an entity that writes to and reads from the storage. One host functions as the storage server, and only one storage server exists for each NetBackup deduplication node. The host must be a NetBackup media server.
How does deduplication work in NetBackup?
With media server deduplication, the NetBackup client software creates the image of backed up files as for a normal backup. The client sends the backup image to a media server, which hosts the plug-in that duplicates the backup data.
What is pure disk in NetBackup?

What is volume pool in NetBackup?
The Policy volume pool attribute specifies the default volume pool where the backups for the policy are stored. A volume pool is a group of media that is grouped together for use by a single application. The volume pool is protected from access by other applications and users.
How do I reclaim deduplication storage space manually?
Solution
- Expire all NetBackup images backed up to the PDDO storage pool.
- Check the Dedupe Storage queue folder.
- Run CR queue processing.
- Monitor processing progress by checking the storage log.
- Run PDDO data removal and wait for 5 minutes (or you can check the job run status in the PD GUI)
- Run Garbage collection.
How do I configure NetBackup media server deduplication pool?

What is MSDP cloud?
About the Media Server Deduplication (MSDP) node cloud tier. Starting with NetBackup 8.3, an MSDP server is able to directly write deduplicated data to cloud object storage.
What is the difference between a volume group and a volume pool?
Volume Group A logical grouping of volumes based on physical location. Whereas the pool is used for actual data, the group is used for administrative work. If you wanted to move all the volumes from one robot to another, you can either move the volumes one at a time or, if they’re all in the same group, move the group.
What is volume group in NetBackup?
A volume pool is a group of media that is grouped together for use by a single application. The volume pool is protected from access by other applications and users. Select a volume pool name from the list of volume pools. Whenever a new volume is required, it is allocated from the volume pool indicated.
How can I tell if Dedup is running?
Monitoring the event log can also be helpful to understand deduplication events and status. To view deduplication events, in File Explorer, navigate to Applications and Services Logs, click Microsoft, click Windows, and then click Deduplication.
What is MSDP used for?
The Multicast Source Discovery Protocol (MSDP) defines a topology connecting Protocol Independent Multicast sparse mode (PIM-SM) domains. MSDP provides inter-domain access to multicast sources in all domains by enabling all Rendezvous Points (RPs) to discover multicast sources outside of their domains.
How do I create a MSDP for NetBackup?

- Log on to the NetBackup master server from the Java console.
- Select Media Server Deduplication Pool.
- Enter the user name, password, and other required details.
- Enter the storage path for MSDP.
How do I set up NetBackup Cloud Catalyst?

- Add Azure credentials:
- Retrieve the default configuration values, update them for the media server nbumedia, and then commit the configuration.
What is the difference between a volume group and a volume pool in NetBackup?
What is volume pool in Veritas NetBackup?
Volume pools are configured in the Media and Device Management > Media node of the NetBackup Administration Console. Ensure that the volume pools you create have sufficient volumes allocated to them (or to a scratch pool if one exists).
What is scratch pool in NetBackup?
The scratch pool is an optional pool that contains the media that NetBackup can. allocate to other pools as needed. If you configure a scratch pool, NetBackup moves. volumes from that scratch pool to other pools that do not have volumes available. Only one scratch pool is allowed.
How do I increase my NetBackup retention?
Solution
- In the NetBackup Administration Console, expand NetBackup Management > Host Properties > Master Server > Double-click on master server > Retention Periods.
- Select a retention level that you want to redefine.
- The policy impact list now displays the names of all schedules that use the selected retention level.
What is Dedup scrubbing?
The Integrity Scrubbing job identifies corruption in the chunk store due to disk failures or bad sectors. When possible, Data Deduplication can automatically use volume features (such as mirror or parity on a Storage Spaces volume) to reconstruct the corrupted data.
How does MSDP pool size affect backup performance?
Significant performance impact has been observed in MSDP storage servers deployed in AWS or Azure, as well as VMware and Docker when the physical LUNs are shared between instances. Often, customers mistakenly believe that setting a high number of data streams on an MSDP pool will increase performance of their backups.
What is the maximum concurrent stream count for a single MSDP?
For example, a single MSDP storage server with a 500TB pool protecting Oracle workloads exclusively at 60K jobs per day was configured with a maximum concurrent stream count of 275. Initially, this was set to 200 and then gradually stepped up to 275.
How much disk space does MSDP take up?
Currently, the MSDP pool can consume the entirety of the appliance, or you can mix and match between Advanced Disk, Copilot share space and MSDP (any or all three) up to the maximum capacity of the system. So for a 5330, you could take 229TB and use it for Copilot, 229TB and use it for Advanced Disk, and 229TB for MSDP, for example.
When are additional MSDP storage servers required?
If those resources are being heavily utilized at the current state of a specific stream count, and yet there are still large numbers of jobs waiting in the queue for a lengthy period of time, then additional MSDP storage servers may be required in order to meet a customer’s window for backups and secondary operations.
