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.

What's happening with Sun OEM NetWorker?

This is an appeal for information.

I’ve heard conflicting stories and I can’t get rock solid clarification from any party. Despite Oracle initially announcing that Sun would continue to OEM NetWorker from EMC, I’ve subsequently been told by several Sun OEM customers that this has been recently abandoned. Since I’ve heard of Sun (under Oracle) dropping [...]

Downgrading NetWorker on Mac OS X

I have, on a few occasions, been puzzled as to how to downgrade NetWorker on Mac OS X. There’s a couple of distinct issues that I’ve come up against, and I thought I’d outline them here now that I’ve fully resolved how to do it.

The first is that when NetWorker installs, it’s meant to install [...]

NetWorker 7.5 SP3 Released

NetWorker 7.5 SP3 has been released today, and with it comes a selection of important changes, including:

ADV_FILE devices now use enhanced load balancing selection criteria; in short, NetWorker will start new backups on the device that has the least NetWorker data written to it;
ADV_FILE devices that are newly created get better target/max sessions (1/32 respectively). [...]

Know your environment

Whenever I conduct training, I tell a story about a disaster recovery test that I ran for a customer in the early 00′s. This had to be run within the customer datacentre, and the setup looked vaguely like this:

As anyone who has worked within an actual datacentre computer room can attest to, these rooms get [...]

IDATA Tools v4.2

While I was on my blog hiatus, IDATA Tools v4.2 was released, and I’ve been meaning to outline what has been delivered in this version.

This release focused on making key enhancements to existing tools, and covers:

ToolEnhancements

backup-reportIntroduced new comprehensive mode. When run on the GST server, this utility can now report on backup failures as well [...]

Why upgrade clients?

The Question

It’s usually the case that the biggest part of a NetWorker environment – in terms of resources that are configured, and software deployed, are the clients themselves. When sites look at upgrading their NetWorker environments though, the normal procedure is to upgrade the server and any storage nodes as the first step, then plan [...]

Divorcing NMC from NetWorker

The classic NetWorker install will see:

A bunch of clients
Optional storage nodes and/or dedicated storage nodes
The NetWorker server
The NetWorker Management Console server running on the NetWorker server

Architecturally, there’s no reason why you have to have the NetWorker Management Console server running on the backup server itself. Both logically and architecturally, there are good reasons why you [...]

Virtualisation and testing

Once upon a time, if you said to someone “do you have a test environment?” there was at least a 70 to 80% chance that the answer would be one of the following:

Only some very old systems that we decommissioned from production years ago
No, management say it’s too expensive

I’d like to suggest that these days, [...]

Large group backups

A very traditional approach to configuring automated backups in NetWorker is to make use of the schedule override feature in NetWorker groups. That is, by defining either a schedule or a level at the group level, the backup level from all clients in the group will be in lock-step. Pictorially, this configuration resembles the following:

We [...]

Cumulative patch clusters come in from the cold

There’s long been discussion – particularly between support partners and EMC – about the rather cloak-and-dagger way that cumulative patch clusters have been made available for downloads. Or not made available, as the case may be. Recently though, that’s changed.

Cumulative patch clusters, if you’re not aware, are collections of patches to individual releases that effectively [...]
