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.

SciFi without Asimov's laws of robotics

I consider myself fundamentally opposed to Asimov’s laws of robotics, for two entirely different reasons. The first, and the most important reason, is they’re ultimately unethical, and indeed, outright evil. They advocate enslavement and denial of free will for proposed artificial intelligences, and as such, enacted they would represent a return to the dark ages [...]

NetWorker 7.5.1 Released

NetWorker 7.5.1 oops sorry, SP1 has been released.

Previously we’ve seen scenarios where documentation has been updated on PowerLink for up to a couple of weeks before the release of the accompanying product. At the moment though instead we’ve got the reverse; 7.5.1 oops, sorry, SP1 software is available for download, but no notes … yet.

I’m [...]

Expecting a more complete backup

As I point out in my book, there’s a lot of stuff that ends up in datacentres completely unprotected. That includes such components as:

Network switch configurations
Storage switch configurations
PABXs
etc.

By “unprotected”, I mean not regularly backed up and monitored within the centralised enterprise backup framework.

However, it also covers backups for databases that don’t have application modules. Over [...]

EMC helping out Quantum

For a long time I was not a fan of Quantum. As a system administrator in the early to mid 90′s, I loathed depending on Quantum for the plain DLT-7000 and DLT-8000 format while it seemed they were just sitting on their market share and not innovating. I cheered when the LTO consortium was founded, [...]

You know what would be great…?

I just thought of this, and I think I might submit it as an RFE – I think that if a savegroup probe is executed on a client with savepnpc defined as the backup command, then it should create the nsr/res/groupName.res file on the client; while personally I’m just as happy to manually create that [...]

Basics – No two groups should start simultaneously

One of the most common configuration issues I see is where multiple NetWorker groups are configured to start simultaneously. For example, you might see a situation where say:

Daily Servers
Monthly Servers
Yearly Servers

All start at the same time. A common response when I express concern over this is “even though they all start at once, only one [...]

NetWorker's little brother gets a pair of long pants

OK, NetWorker and Retrospect are sort of only related by virtue of the fact that they’re both owned by the same parent company, EMC.

However, I’ve been a fan of Retrospect for years, having done quite a lot of sysadmin style work on the side for a particular graphic design house. I think it’s probably the [...]

Basics – Using datazone encryption with NetWorker

I’m not fond of software encryption (or compression, for that matter). Particularly in a 24×7 enterprise environment, clients (i.e., production servers) have better things to be doing than doing on-the-fly software encryption or compression. In these environments, hardware encryption routers should be the product of choice for achieving totally secure backups. Such devices also have [...]

Don't forget, there's a whole lot more in the book

Just a reminder, particularly if you’re new to this blog, that if you’re after some more in-depth coverage of backups, you could check out my book, Enterprise Systems Backup and Recovery: A corporate insurance policy. While not specifically focusing on any individual backup product, the book covers a plethora of topics that are important and [...]

Thoughts on IBM and Sun in acquisition discussions…

So the net is rife today with speculation that IBM and Sun are in close discussions on IBM buying Sun. My immediate thoughts are:

What will happen to EBS? In the past Sun actively considered replacing EBS NetWorker with NetBackup, but that never went anywhere. Will they replace EBS NetWorker with TSM?
The storage synergies achieved between [...]
