NBU 5220 Performance
We recently deployed a 5220 appliance into our environment as it was to be the savior in our battle against a backup window we were no longer able to meet. When we finally got it online and into our NBU environment the initial performance was great. The area we were to most benefit was with VMware backups. The data stores mounted directly to the appliance would allow direct access to the snapshots for a fast and efficient backup. Before this, we were performing client side backups so the impact on the hosts every night was significant as we tried backing up 600+ vms. The plan was to be able to move all Dev and test off-host backups to the middle of the day as the performance impact was minimal and the end result was an increased window to complete things. As we started with noon-time backups deduplication rates were high and so were the speeds. However, this performance gain was short lived, as we began increasing the load we suddenly saw performance drop to a point of concern. Backups were no longer speedy, 3500KB per second to 10,000KB. There are some that might pop to 24,000KB, but in a sample size of 15 as I write this, only one is showing 24,000. Now, I do have a few ideas. 1. We have a 72TB appliance, therefore, 2 disk trays, during the backups, the one disk tray is going crazy, all the lights are flashing and you can really see that it is working. However, the second tray is doing nothing. While you might see a blink here or there, it is almost nothing compared to the other disk tray. Is this to be expected? When we looked at the disk configuration, it shows concat, is this normal? 2. Too much data at once and we are simply burying the appliance. In reality, what sort of performance should I be able to expect from the appliance? 3. Relating to number 2, since we only have the one appliance right now while we wait to get the remote appliance in place, we are duping off to tape. This is running at the same time as a backup, so this means at the same time the appliance is writing a lot of data, it is also reading it back to tape. 4. We are overloading the data store so that read speed is bad from source to destination. We have fewer hosts,therefore, if we limit the jobs per host we limit the number of machines backing up at once (obviously). This means that backups take way long, so we removed the limit per host and just set a limit per data store. As we are new to it all, I am not sure what impact where, but again, I am trying to list any and all ideas from the start. 5. The appliance does not support multi-pathing, therefore, we only have a single path to the disk. Beyond that I am not sure, but this is something that doesnt help with the showcasing of the appliances to management at the moment. However, given the initial performance I am confident we can get back there.

duplications from wrong media server
I have two 5200 appliances (2.0.1) one is in our primary data center and one is at our DR site connected by a 43mb pipe. My primary appliance has two LTO tape libraries directly attachedvia fiber that are used for doing monthly backups. I am using SLP's for the back up and duplications. Every weekend we do a full backup (1.3tb)that is backed up to my primary appliance and then duplicated to my DR appliance.During this backup i notice that my media server that is being used is primary > primary (for backup) and DR > DR (for duplications). This is perfectly fine. Now heres the trouble. When i mix a duplication to tape in this process the system trys to load balance the duplication between my media servers. Meaning: One duplication job will show the primary as the media server for the tape backup and one job will show the DR appliance. This would all be ok if the DR appliance was on my local LAN but it is not and therefore any duplication using it as the media server to tape can take over 24 hours to complete. In the SLP for my monthlys I have removed the DR appliance as a duplication so i dont know why it keeps responding. Example: i had a 245gb exchange DB duplication thatwas usingmy DR appliance as the media server and it had been running for 48hours and was only 60% complete. I noticed the job and cancled it. When it retried it picked up my primary appliance as themedia server and in25min it was complete(over fiber channel). I opened a ticket with support 2 months ago but we have yet to figure out the deal. This hasnt been that big of an issue until another group wanted to replicate some VTL's to the DR and realized that the bandwith is 100% consumed all the time by netbackup. i have been tinkering with this for months and cannot figure out what i have configured wrong so i want to consult the almight Community for answers. LOL! To me it sounds like the media servers are setup so that they can load balance but i cant find were to disable that.

Hello, Firstly, this is a big company, nearly 20-25 TB data is backedup as weekly full backup. I think the problem occurs when i have duplication and backup processes at the same time. Randomly some db backup fails with 6 errors at the middle of job. Sometimes i make rebase is off and these errors are lower than to rebaseon. After a fail, i retry to job and it mostly finishes successfully. i dont exactlyknow which logs are needed. i try to explain my envoirement. Master -> 7.5.0.7, windows 2008r2 Media -> 5220 appliance, 2.5.4 Clients ->windows 2008r2, sql2008 i found some link about the issue, but i dont know exactly these changes work or not. http://www.symantec.com/connect/forums/interrupt-when-backup-large-sql-databases http://www.symantec.com/connect/forums/5220-limits?page=0#comment-10092541 Thanks a lot

Compelling reason not to include eth0 in bond0 on NB5230 v2.6.0.1?
Hi, Is anyone aware of a compelling reason why we should not include eth0 in an 802.3ad bond0 (of 4 x 1Gb eth0/1/2/3) on an NB5230 master/media running v2.6.0.1? Is it officially supported in v2.6.0.1, and also in v2.6.0.2, and going forward long term? Thanks.
