I've watched following sort of comment appear periodically on thislist and in the past I've tended to let it slide.

It has never been an enterprise product.

Not this time. I think Tim Mooney and another person added somewhat tothis discussion but I want to add one thing.


Backup dependencies.

I often see NetBackup bandied about as the "be all and end all" ofenterprise backup products, but it doesn't do dependency tracking - itjust throws away images as soon as they're expired regardless of anyretention time that might be otherwise considered for an entirefilesystem backups. Is that something you'd expect to see in anenterprise backup product?

I'm not wanting to start a "my product is better than yours" war;there are a heap of features in NetBackup that annoyingly aren't inNetWorker - inline cloning and savesets being able to migrate from onefilled disk backup unit to another are two key examples.

Regardless though, what makes a backup product an enterprise productis as much as anything based on whether it scales and works withinlarge enterprises. Its fair to say NetWorker has this in spades. It isdeployed in very large organisations, it supports multiple tiers andcentralised management over those tiers, does all the things you'dexpect of enterprise products (multiplexing, spanning, rapid dataaccess, etc) and is _fast_. Or rather, it's as fast as yourenvironment can handle. (Don't believe me? 2.86GB/s, 10TB/h is apretty good starting point - and that was done in 2003? 2004? byLegato, SGI and McData, from memory.)

So, let's not get into debates about whose backup product isenterprise and whose isn't. The question is too much like theproverbial "how long is a piece of string?" question.


Cheers,

Preston.
