Regular visitors will have noticed that has been down quite a lot over the last week. I’m pleased to say it wasn’t a data loss situation, but it was one of those pointed reminders that just because something is in “the cloud” doesn’t mean it’s continuously available. In the interests of transparency, here’s what happened: […]

NetWorker 8.2 SP2 is here

While NetWorker 9 went DA at the end of September and is seeing healthy uptake around the world, NetWorker 8.2 is still getting updates. Released a couple of weeks ago, NetWorker 8.2 SP2 includes a slew of changes. While undoubtedly NetWorker 9 will be seeing the majority of new-feature development henceforth, that’s not to say that NetWorker 8.2 won’t […]

Multihost consistent backups in NetWorker 9

NetWorker 9 introduces a new action that can be incorporated into workflows, Check Connectivity. You can use this prior to a backup action to confirm that you have connectivity to a host before starting the backup. Now, you may think this is a little odd, since NetWorker effectively checks connectivity as part of the backup process, but that’s […]

Linux Block Based Backups in NetWorker 9

As mentioned in my introductory post about it, NetWorker 9 introduces the option to perform Block Based Backups (BBB) for Linux systems. (This was introduced in NetWorker 8 for Windows, and has actually had its functionality extended for Windows in v9 as well, with the option to now perform BBB for Hyper-V and Exchange systems.) BBB is a highly efficient […]

NetWorker 9: The future of backup

Introduction When NetWorker 8 was released I said at the time it represented the biggest consolidated set of changes to NetWorker in the all the years I’d been working with it. It represented a radical overhaul and established the groundwork for further significant changes with NetWorker 8.1 and NetWorker 8.2. NetWorker 9 is not a similarly big set of changes: it’s […]

The LTO consortium has announced: That the LTO Ultrium format generation 7 specifications are now available for licensing by storage mechanism and media manufacturers. LTO-7 will feature tape capacities of up to 15TB (compressed) and streaming speeds of up to 750MB/s (compressed). LTO is now working off a 2.5:1 compression ratio – so those numbers are (uncompressed) 6TB […]

Melbourne DPUG and VMware Data Protection

Recently a colleague and I initiated the Melbourne Data Protection User Group (DPUG). If you’re interested in joining and participating and based in Melbourne, you can find details for the user group over at Meetup. Our first presentation was on Wednesday 9 September, and EMC Melbourne were kind enough to provide the office space for the session. […]

Updated checks in nsradmin

A while ago EMC engineering updated the venerable nsradmin utility to include automated checking options, with an initial focus on checks for NetWorker clients. As a NetWorker administrator I would have crawled over hot coals for this functionality, and as an integrator I found myself writing Perl scripts from company to company to do similar checks. As of NetWorker, the […]

Sampling device performance

Data Protection Advisor is an excellent tool for producing information about your backup environment, but not everyone has it in their environment. So if you’re needing to go back to basics to monitor device performance unattended without DPA in your environment, you need to look at nsradmin. Of course, if you’ve got realtime access to the NetWorker environment you […]

Recovery survey

Back in 2012, I ran a survey to gauge some basic details about recovery practices within organisations. (The report from that survey can be downloaded here.) It’s been a few years and it seems worthwhile coming back to that topic and seeing how things have changed within NetWorker environments. I’ve asked mostly the same questions as before, but […]
