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.

There’s been some discussion in the EMC Community Forum lately as to whether it would be handy to have a directive preview option in NMC. I’d suggest it is, but if you need this now then you don’t have anything to wait for, so long as you’re willing to work on the command line.
The way [...]
While I touched on this in the second blog posting I made (Instantiating Savesets), it’s worthwhile revisiting this topic more directly.
Using ADV_FILE devices can play havoc with conventional tape rotation strategies; if you aren’t aware of these implications, it could cause operational challenges when it comes time to do recovery from tape. Let’s look at [...]
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 [...]
I had hoped that the NetWorker Power User’s Guide to nsradmin micromanual might be popular enough to get say, at least 50 or 100 downloads, but I’ve been overwhelmed by the hundreds and hundreds of downloads.
That high number of downloads has well and truly been reflected in the fact that the article introducing the micromanual [...]
Yesterday I experienced one of those weird NetWorker issues that is such an odd combination of factors that I felt it had to be discussed.
Here’s the scenario. A customer was:
Previously running NetWorker 7.4.2 on their backup server.
Upgraded the server to 7.5.1.
Had a bunch of Windows clients and one Unix client.
The Unix client was configured for [...]
There was a recent posting on the NetWorker mailing list regarding manual backups and whether they’re incrementals or not. The short answer of course is they’re not. The more challenging answer is whether or not you can actually generate a manual incremental backup.
You may think that as of 7.5 onwards, where the level is expressly [...]
Some time ago, I posted that EMC had added a jobquery utility to allow probing of the NetWorker jobs database (the one created/maintained by nsrjobd). Unfortunately, at the time, jobquery had been somewhat muzzled – you could give it commands, and it would spit output back to you, but it would never give you any indication [...]
While much of NetWorker 7.6′s enhancements have been surrounding updates to virtualisation or (urgh) cloud, there remains a bunch of smaller updates that are of interest.
One of those new features is the validcopies flag, something I unfortunately failed to check out in beta testing. It looks like it could use some more work, but the [...]
Something that continues to periodically come up is the need to remind people running manual staging to ensure they specify both the SSID and the Clone ID when they stage. I did some initial coverage of this when I first started the blog, but I wanted to revisit and demonstrate exactly why this is necessary.
The [...]
When I first mentioned probe based backups a while ago, I suggested that they’re going to be a bit of a sleeper function – that is, I think they’re being largely ignored at the moment because people aren’t quite sure how to make use of them. My take however is that over time we’re going [...]
