It is my understanding that Avamar is a self contained backup software and storage with deduplication. As far as I know, Networker does not have any built in modules that allow NW to deduplicate data. If it does, I want to know!
That said, with Networker, you can semi manage Avamar deduplication backups. You can direct client backups to the Avamar node and then the Avamar software takes over and processes the backup. The HUGE advantage of Avamar is two fold: Client side deduplication processing which dramatically reduces data across the pipe and variable block level deduplication, this is why you typically see dedupe ratios in the 98th percentile and beyond. The downside to Avamar is it is extremely expensive to maintain and upgrade.
We are running Avamar/ Networker setup. The Networker is 7.5.1. It is running smoothly. We are using this specially for Offsite backups that have narrow pipes. In some cases we do a backup at the offsite server to a portable media and move the backup to an onsite server and back that server onsite (this is quicker). In one case the full bakup of a server took one week when doing it without Avamar.
Then when the offsite server is backuped the data is there and little transfer is needed.
I can higly recommend the Avamar. The deduplication depends on the type of data and I cant really say for sure what the percentage exactly is.
We are running with Networker/Avamar integration and it works pretty well other than some quirkiness with reporting.
Bottom line is you need to have an Avamar target (think of this like buying a tape SILO) that is either the hardware appliance or software running in front of some storage that you will point Networker. So unfortunately the Networker integration with Avamar is free, but you need to buy Avamar to leverage de-duplication. The change is that the Networker client starting in version 7.4.2 includes the Avamar client libraries with the Networker client.
What gets really confusing is you could have your Avamar environment hosting backups on its on as well as Networker backups running against the node.
The reason we have this setup is to allow us to have all of our backups (duplicated via Avamar) and non-deduplicated managed by a single interface/process.

I hope that helps.
