Enterprise Systems Backup and Recovery If you have an interest in, or work in data protection/backup and recovery environments, you should check out my book, Enterprise Systems Backup and Recovery: A Corporate Insurance Policy. Designed for system administrators and managers alike, it focuses on features, policies, procedures and the human element to ensuring that your company has a suitable and working backup system.

While this is pertinent to all versions of NetWorker, it particularly seems relevant mentioning now, since as of 7.5.2, we’re now seeing revised messaging from NetWorker when a tape becomes prematurely full. These new messages now state:
nsrd media notice: LTO Ultrium-4 tape 800814L4 used 2039 MB of 800 GB capacity
nsrd media notice: NetWorker media: (Warning) [...]
As I mentioned in a post yesterday, NetWorker 7.5.2 (or NetWorker 7.5 SP2) has been released, and with it comes a bunch of feature enhancements as well as a slew of bug fixes.
One of the criticisms of EMC’s development process for NetWorker for a while was that a new service pack would come out with [...]
Typical that it happens on a day when I’m travelling, but NetWorker 7.5 SP2 (aka NetWorker 7.5.2) has been released today.
There’s a bunch of updates and bug fixes in this release – I actually have really high hopes for it based on discussions I’ve had with various folks at EMC. I’m about to start an [...]
The scenario:
A clone or stage operation has aborted (or otherwise failed)
It has been restarted
It hangs waiting for a new volume even though there’s a partially written volume available.
This is a relatively easy problem to explain. Let’s first look at the log messages that happens. To generate this error, I started cloning some data to the [...]
Is your backup system a unicorn, or is it a horse?
If you’re thinking I’m off my rocker asking such an odd question, don’t worry, I haven’t temporarily taken leave of my senses. To assure you that I haven’t taken an odd turn, this is a continuation of a previous post – How Complex is your [...]
Covered in several places last week, including The Standalone Sysadmin, was the story about Dell updating their RAID firmware/systems on the latest PowerEdge servers to block the use of non-Dell supplied disks.
The offending support letter from Dell (quoting as per Standalone Sysadmin) reads:

There should be more software installed on your NetWorker server than just the operating system and NetWorker. In order to get the most out of it, you should have a toolkit of utilities and applications that are there, at your beck and call, to help you get the most out of your backup system.
It doesn’t [...]
Over at Xiotech’s blog, there’s an interesting piece about the evolution of 2.5″ drives in enterprise storage titled The Great Shrinking Disk Drive.
I’m not 100% convinced of Xiotech’s argument, but over the years I’ve seen increasing use of 2.5″ drives in enterprise computing – particularly to decrease the footprint and power requirements for DAS in [...]
We’re used to seeing EMC and NetApp punch it out in the blogosphere and tweetverse, with the occasional pause from both of them to have a minor dust-up with the likes of HP, IBM or HDS, but component manufacturers don’t seem to normally go for such … abrasive^H^H^H^H^H^H^H^Hdedicated … web behaviour.

I frequently work in support – I help a plethora of companies that have NetWorker issues, and I enjoy doing that work because it’s about fixing their issues and either getting them up and running again (if it was a serious issue), or helping them with something they’d not done before.
In short, I like helping [...]
