Basics - Configuring a reports-only user

Something that’s come up a few times in the last year for me has been a situation where a NetWorker user has wanted to allow someone to access NetWorker Management Console for the purpose of running reports, but not allow them any administrative access to NetWorker. It turns out it’s very easy to achieve this, and […]

Pool size and deduplication

When you start looking into deduplication, one of the things that becomes immediately apparent is … size matters. In particular, the size of your deduplication pool matters. In this respect, what I’m referring to is the analysis pool for comparison when performing deduplication. If we’re only talking target based deduplication, that’s simple – it’s the size of the […]

NetWorker to the Cloud

Introduced alongside NetWorker 8.2 SP1 is integration with a new EMC product, CloudBoost. The purpose of CloudBoost is to allow a NetWorker server to write deduplicated backups from its datazone out to one of a number of different types of cloud (e.g., EMC ECS Storage Service, Google Cloud Storage, Azure Cloud Storage, Amazon S3, etc.) in an efficient […]

One target to rule them all

Introduction It’s true there are some data types that broadly aren’t suitable to sending to Data Domain – any more than they’re suitable for sending to any other deduplication appliance or system within any environment. Large imaging data and video files will yield minimal deduplication except over successive backups (assuming static data), and compressed and/or encrypted data aren’t all suited either. But the majority of data […]

Files and files and files

A while ago, I gave away a utility I find quite handy in lab and testing situations called genbf. If you’ll recall, it can be used to generate large files which are not susceptible to compression or deduplication. (You can find that utility here.) At the time I mentioned another utility I use called generate-filesystem. While genbf is designed to produce potentially very […]

New role

I’m pleased to say that on Monday I’ll be starting a new role. While I’ve worked closely with EMC for many a year as a partner, and more recently in a subcontracting position, come Monday that’ll all be changing… …I’m joining EMC. I’ll be working in the Data Protection Solutions group as a sales engineer. I’ve […]

Basics - Taking a turn about the filesystem

“Miss Eliza Bennet, let me persuade you to follow my example, and take a turn about the room. — I assure you it is very refreshing after sitting so long in one attitude.” Jane Austin: Pride and Prejudice. The NetWorker savegrp command has a lot of different command line options, but one which falls into that […]

Upgrade times

We live in a world of activities. Particularly in IT, almost everything we do can at some point be summarised as being an activity. Activities we perform typically fall into one of three organisational types, viz.: Parallel – Activities that can be performed simultaneously Sequential – Activities that must be performed in a particular order Standalone – Activities that can be performed […]

Turbocharged EMC NetWorker, v1.1

Today I’m announcing the availability of Turbocharged EMC NetWorker, v1.1. As you can imagine from the version number, this is an incremental update rather than a substantial revision of the previous document. The change log for the updated manual is as follows: Added details on the nsradmin -C option for automated client probes Added details for reporting on VBA […]

World backup day misses the point

It’s fair to say I’m a big fan of backup and recovery. So much so that a substantial part of the last 19 years of my career have been devoted to it in some form or another. Yet here’s the rub: World backup day (March 31) is full of good intentions but has entirely the wrong focus. By that […]
