[Veritas-bu] Upgrade to NBU 6.0 or wait for 6.5...
Hi all, We run NBU 5.1 and are considering to upgrade to 6.0 in Q1 next year.. But what I have understood Symantec will release NBU 6.5 in summer time 2007. Of course there can be delays in 6.5 delivery and it may or may not bee unstable.. But anyhow, what are your plans if you run 5.1?

Re: [Veritas-bu] Upgrade to NBU 6.0 or wait for 6.5...
6.5 !! you may want to review documents for 6.0 - dont think this would be out until late 2007 surely! As for easy upgrade to this version again, could not tell you or even comment on this! If 5.1 does what you want it to do, then you may want to stick with this. If version 6.0 offers extra benefits that you need, then review the possibility of upgrade or migrate to a clean install.

Re: [Veritas-bu] Multithreaded / Multicore CPUs
NBU forks multiple processes per job so you should benefit from multi-core CPU's. However, since backup/restore depends greatly on data input (network) and output (tape/disk) you should ensure everything in the data path (drivers, etc) can utilise multiple processes.

Re: [Veritas-bu] Upgrade to NBU 6.0 or wait for 6.5...
Phil, 6.0 is the release that did the multithreading thing. I am not sure if all of netbackup is now multithreaded, but much of it is. For us the early 6.0 was really unstable, but we had several problems with 5.1 that were fixed with 6.0. (Because netbackup 5 was not multithreaded we had timeouts which lead to different socket errors when running more then one backup stream to a client). The 6.0 MP3 patch fixed many of the multithreading issues and MP4 added many more fixes. As 5.1 was not perfect, it may be to the point where 6.0 MP4 is better. It all depends on the options you are using, the hardware you are using, and the attributes of your workload. len From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Weber, Philip Sent: Thursday, November 23, 2006 5:54 AM To: Hampus Lind; veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] Upgrade to NBU 6.0 or wait for 6.5... Due to the emails I've seen on this list about 6.0 issues, I plan to stay on 5.1 until I have a pressing need to upgrade or 6.0 seems to have settled down. Apparently 6.5 may be multithreaded, which might influence my decision based on some hardware that is also coming in the door. Mind you, that suggests a re-write, so maybe we'll expect lots of problems with 6.5 when it comes out?

Re: [Veritas-bu] ACSLS Question
Justin, You don't need SSO to share the ACSLS library. One of the media servers should be the robotic control host, just like with a normal SCSI library. I think you'll need to define the library on each media server, but specifiy your first media server as the control host. You'll need SSO if you want to dynamically share the drives inside the library between media servers.

On 11/23/2006 12:47 PM, Scott Jacobson wrote: What was the alias Ed was referring to It's an emm alias. If your master or media servers have multiple NICs, they probably also have multiple names. In this case, you need to tell emm which alias correspond to which. For example, if you have foo.stp.example.com and foo.bck.example.com both pointing to the same server, you'd define that as an alias. My guess is that there was a bug in early 6.0 releases that sent the data out the wrong interface and it was fixed in MP4, causing the emm authentication to fail. This is just a guess though...
