Deduplication Option

[H_Sharma]

Hi Experts,

Please let me know which setting will override in Deduplication?

1:- Policy:- Disable Client side policy. 

2:- Client attributes in master server properties :- Prefer to use client side dedupe.

2:- Is Media server dedupe only done in puredisk?

3:- If we need to configure Dedude in Client side. Do we require any thing else apart from below?

    1:- Every Client with 64 Bit O/S, 4 GB RAM, CPU 2.2 GHZ with 8 CORE?

     2:- Enable the dedupe in Client attributes in master server properties :- Prefer to use client side dedupe.?

Thanks so much.

For the first 2 the policy setting will override the client attributes setting and de-dupe will happen on the media server

Media Server de-dupe is done with PureDisk, MSDP and in some ways also when using OST de-dupe as the de-dupe is done on the OST device

3 .1 64 bit supported O/S yes - the others are reccomendations but worth having

3.2 This should do the trick - if the client can do it then it will run as client side

Hope this helps

Hi Mark,

Thanks for your reply.

I understood that we could use Pure Disk and OST for Media Dedupe right?

Effectively yes - you can use PureDisk as a target disk pool for your backups within NetBackup and it gets referenced via your Media Servers.

The details are all in the deduplication admin guide.

It is just the terminology that you dont quite have right as media server dedupe is known as MSDP which means that the disk resides on the media server which has its own built in de-dupe engine - where as PureDisk is a seperate system with its own disk and de-dupe engine that your media servers use via OST

Hope that makes sense
