Honestly, NBU isn't a bad product. It's been around a long time, and if you use it in the traditional backup and recovery sense, it works quite well. Its database doesn't scale the way DB2 does, naturally.
When we were rebuilding our datacenters 6 years ago, TSM was in the running. We got the new version in to test, and a specialist from IBM came in to configure it in our lab. By the end of the five days, it still wasn't working. NBU was set up and running in about 2 hours. It's not nearly as powerful as a data management platform, and can't scale, but it's ridiculously simple compared to what TSM was. The other issue was that at the time, we were looking at dedupe tech and moving away from tape. TSM just wasn't there yet. NBU was pretty much leading at the time, especially with integration with dedup. And, to be clear, NBU is actually working great in our environment when we use it for traditional client-based backups. It's only the NetApp snapshot integration with VMWare that's lacking, but that's where we want to go. -Adam On Thu, Oct 29, 2015 at 5:05 PM, Michael Ryder <mryder1...@gmail.com> wrote: > I haven't heard *anything* nice about NBU, sorry. > > Are you able to say why they dropped TSM?
