Puredisk Vs Inbuilt Dedupe in 7.0 - Comment:14 Jan 2013 : Link

See this NBU 7.0 FAQ:

http://eval.symantec.com/mktginfo/enterprise/other_resources/b-netbackup_7_faq.pdf

Extract from p. 2:

Q. How is deduplication in Netbackup 7 different than in PureDisk 6.6?

A. The NetBackup 7 deduplication technology uses the same engine as PureDisk. The biggest difference is that with NetBackup 7, there is no separate install; dedupe is built into NetBackup 7. NetBackup PureDisk continues as a viable option for customers who have unique requirements or large installments (petabytes of data).

Thanks for reply. Got confused as I am new to Netbackup. Few Question More

1:-what is the engine here?

2:- does built in dedupe require any additional hardware or software? I belive it is for Disk based backup and can be later archived to tape?

3:- does built in dudupe for small oraganization?

1. 'the engine' is the dedupe software

2, As per above extract from FAQ: ' there is no separate install; dedupe is built into NetBackup 7'. This means no separate software. You will need dedupe license key, As far as hardware is concerned - you need a media server with enough resources that supports dedupe and a big enough disk attached to your media server,
Please see requirements in 7.0 Dedupe Guide:

NBU Deduplication Guide http://www.symantec.com/docs/TECH127071

NBU Deduplication: Additional Info http://www.symantec.com/docs/TECH77575

Backups on dedupe disk can be duplicated to tape.

3. Built in dedupe is ideal for small organizations.

Best to upgrade to 7.1.0.4 or 7.5.0.4 as many dedupe bug fixes and improvements have been added to recent versions of NBU.

Hi Belse

The time you would like to protect the data in is also important(12hours to do 4TB of Backups or whatever). Whatever the requirement is, it will also play a part in the resources and infrastructure required to protect your data in the required time.
