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.Solved1.9KViews4likes6Comments
When too much process on appliance, randomly some of database backup fails at the middle of process
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 lotSolved1.4KViews3likes6Comments
Symantec 5230 Appliance - Disk Space Warning Message
I am receiveing an emailalert (Warning) each morning relating to disk space utilisation on the de-dup pool in my 5230 Appliance (which is at 80%) and wish to raise the threshold for the warning to 85%. The appliance is sitting steady at 80% so I am not too concerned. Where can I change the limit ? Thanks, AJSolved1.6KViews3likes3Comments
SNMP configuration for 5020-DeDupe appliance & 5220-MSDP
Is there any way to add a query to MIB list to recive an alert in trap reciever(SNMP server) fromDeDupe appliance & 5220-MSDP, whenever entire pool goes down(Situation when backup fails with status 2074). How can I change the priority for MIB lists ???? Regards, BharathSolved655Views3likes1CommentNetbackup Appliance 5230 - /disk: Input/output error
Hi. Good day! Need someone to point me to the right direction please. We've been using the appliance for almost two months now and it has recently been encountering mount issues with a specific volume. This volume contains all our backup data and my fear is that if it becomes corrupted then I would lose critical data. error: df: `/disk': Input/output error what is the best way to protect this data? can i do a tape backup for the contents of the filesystem? what is that process called? or is there any alternative? thanks in advance. alain1.4KViews2likes7Comments
Buffer Settings for Duplication to LTO 5 Tape
We're using a Netbackup 5230 Appliance connected via 8Gb fibre to an HP MSL 8096 LTO 5 tape library with 4 drives. I've read many posts recommending leaving the buffer size as default: SIZE_DATA_BUFFERS : 262144 (Default) SIZE_DATA_BUFFERS_DISK : 262144 (Default) SIZE_DATA_BUFFERS_FT : 262144 (Default) This is how they are currently set, and when monitoring backups to disk, I see the following in the log: 01/29/2014 19:49:09 - Info bptm (pid=3752) using 262144 data buffer size 01/29/2014 19:49:09 - Info bptm (pid=3752) using 30 data buffers Which is expected, however, when duplicating to tape, the logs indicate the following: 01/31/2014 17:00:15 - Info bptm (pid=30607) using 65536 data buffer size 01/31/2014 17:00:15 - Info bptm (pid=30607) using 30 data buffers Can someone clarify why it would be set this way and is this as expected?

Enabling Native Tape Drive Compression on LTO5 and LTO6 Drives
Does anyone have a walk through on enabling tape drive compression(NOT software compression)? I've been doing some research and it appears commands such as: sdparm - <device>, and sginfo -a displays the following information: Data compression (SSC) mode page: DCE 1 [cha: y, def: 1, sav: 1] DCC 1 [cha: n, def: 1, sav: 1] DDE 1 [cha: n, def: 1, sav: 1] RED 0 [cha: n, def: 0, sav: 0] COMPR_A 255 [cha: n, def:255, sav:255] DCOMPR_A 255 [cha: n, def:255, sav:255] I have 6 Netbackup 5200 and 5220s connected to an IBM3584 with 12 LTO4, 5, and 6 drives via FC. The library and drives are functioning however, I'm not getting no where near the data compression on the LTO6 tapes that I thought I would. I'm only seeing about 3.1TB on a LTO6 tape. Can someone explain the output above and what my settings should be. Thanks.Solved6.9KViews2likes7CommentsUser Access Management on Appliances
Hi all, Am I reading it right that User Access Management, because it's part of the NBAC, isn't available on the NetBackup Appliances? Does this mean either I can give users admin access or nothing at all? I am aware of the command line ability to assign a role to a user/group to allow them CLISH or Shell, but I was hoping to at least use the built in roles in NetBackup and am surpised to see this not available for Appliances. Thanks in advance. RichardSolved1.2KViews1like4Comments
Netbackup Appliances is stucking over the night in the backup window
Hello, We are running netbackup master on a windows 2008 sp1 r2 server. In addition, all our backups go to 4 appliances that function as Media servers. Recently, we encountered long backup times. Sometimes, backups get stuck, causing other backup jobs not to start running and finnally cause them to abend with a 196 code. Please advise.Solved1.4KViews1like8Comments
