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.

As I mentioned in an earlier post, EMC have announced on their community forum that there are some major changes on the way for ADV_FILE devices. In this post, I want to outline in a little more detail why these changes are important.
Volume selection criteria
One of the easiest changes to describe is the new volume [...]
I had been aware for a while from an NDA conversation that these changes were on the way, but of course have not been able to discuss them.
However, with EMC opening up discussion on the EMC Community Forum – i.e., out in public, I now feel that I can at least discuss how excited I [...]
In the previous article, I covered the first five of ten reasons why tape is still important. Now, let’s consider the other five reasons.
6. Tape is greener for storage
Offline storage of tape is cheap, from an environmental perspective. Depending on your locality, you may not even have to keep the storage area air-conditioned.
Disk arrays and [...]
Various companies will spin you their “tape is dead” story, and I’m the first to admit that the use pattern for tapes is evolving, but to anyone who claims that tape has lost its relevance, I’ll argue otherwise.
This is part 1 of a 2 part article, and we’ll cover reasons 1 through 5 here.
1. Tape [...]
Close enough together that I have to declare them a tie, the top stories for February were:
micromanual: NetWorker Power User Guide to nsradmin, and
Carry a jukebox with you (if you’re using Linux) [plus the follow-up article, NetWorker and linuxvtl, Redux].
It’s fair to say that Carry a jukebox with you is remaining a big hit all [...]
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) [...]
Any regular reader knows that I don’t for a minute believe that tape is dead. However, it is time to address the changing use for tape within the enterprise datacentre, and what we’re going to see in the coming decade.
To start with, let’s examine the traditional role within tape within enterprise backup and recovery. Long [...]
I’ve debated for a while whether to do this or not, since it might come across as somewhat twee. I think though that in the same way that “My Very Eager Mate Just Sat Up Near Pluto” works for planets, having an A-Z for backups might help to point out the most important aspects to [...]
Looking at the stats both for this new site and the previous site, I’ve compiled a list of the top 10 read articles on The NetWorker Blog for 2009. The top 3 of course match the three articles that routinely turn out to be the most popular on any given month, which speaks something of [...]
A common mistake I see people make when planning VTL implementations is to aim to keep virtual media of a similar size to physical media they intend to stage/clone out to. For example, if planning to first backup to a VTL, then transfer out to LTO-4, a lot of people start planning around having virtual [...]
