High CPU utilization due to many BPBKAR process
Hi All, I havea query, Today found a server in which CPU utilization was high upto 95%. When checked on the server, found many BPBKAR process were running there. That was obvious because backup for that server running, Is there a way we can minimize CPU utilization while "BPBKAR" process and backup keep running ? Means without affecting backup, can we make CPU utilization normal. Please advice and suggest...

Jobs in queued state: Waiting in NetBackup scheduler work queue on server :
Hello Everybody, We are seeing this all the jobs. I have checked other threads related to same problem but none of them helped. Nothing is moving in the environment, almost every backup is failing with 196 after staying in queued state. We opened a severity one case with support they are asking to increase the memory, we have ordered the new memory. But I am seeing no sighns that server is running out of memory or something like that. Anytime there is nearly 3 GB available of physical memory. Below is the output from one job. 8/22/2014 9:32:39 AM - Info nbjm(pid=12846) Waiting in NetBackup scheduler work queue on server 8/22/2014 9:34:41 AM - Info nbjm(pid=12846) Waiting in NetBackup scheduler work queue on server 8/22/2014 9:36:41 AM - Info nbjm(pid=12846) Waiting in NetBackup scheduler work queue on server 8/22/2014 9:38:41 AM - Info nbjm(pid=12846) Waiting in NetBackup scheduler work queue on server 8/22/2014 9:40:41 AM - Info nbjm(pid=12846) Waiting in NetBackup scheduler work queue on server 8/22/2014 9:42:41 AM - Info nbjm(pid=12846) Waiting in NetBackup scheduler work queue on server 8/22/2014 9:44:41 AM - Info nbjm(pid=12846) Waiting in NetBackup scheduler work queue on server 8/22/2014 9:46:41 AM - Info nbjm(pid=12846) Waiting in NetBackup scheduler work queue on server Secondly I tried this command as given in another thread just to check the scheduler queue but no use. nbpemreq -jobs screen all Maximum output size exceeded, see log We have already tried restarting the NBU, rebooting the master server but this things creeeps up every time. Everything is so slow now. If we triggering a job using bpbackup it takes good 20 minutes to show up in activity monitor. Tapes drives are free but still NBU is not able to assign them for the waiting job and those jobs are just waiting for the drives to continue. I am not sure which logs to provide. Let me know which logs and what other info is needed to look into this. Environment info: NBU 7.5.0.5 running on Solaris 10 20+ media server sharing same DD and Tape library SLP Duplication is used

Very Slow VM Backups
Hi, We are currently using Network based VM backups rather than SAN based, the Backup Host is a Windows 2008 server running NBU7.5.0.5 and has full access to the ESX servers, I have several policies set up including VIP's for covering the VM's. The back bone is a 1Gb LAN, the Backup Host is SAN attached to an HP VLS12000 which is emulating LTO4 drives, this is on 4Gb F/C When backing up the VM's I am only seeing on average 1.5M/s throughput, we have standard clients that are using the conventional NBU method whuch reach over 40M/s through the same medium. Just wondered if there were any tuning or other paramaters that we need to look at with the VM backups to speed them up. Kev

Backup image expiration cannot be modified because its SLP processing is not yet complete
We are using NBU 7.6.0.4, Windows Server 2012 R2 Standard. I need to check if the item is duplicated or not. Or if it is SLP not complete, I want to forcefully put it on tapes.

NetBackup Status Code 24 - Possible Parameters to Check
Hi Friends Receiving Status Code 24 is now becaming very common in our Infrastructure, where we are backing up alomost 7000 boxes using 10 different master servers. I agree there is a Technote Available from Symantec : http://www.symantec.com/business/support/index?page=content&id=HOWTO50801 for troubleshooting Status Code 24 Failures, but most of the time we are getting the situation where this is not enough to fix the issues. Can someone please help me to understand that what are the parameters need to be checked in Client / Media / Master server and the tuning can be made to fix the issue. Also is there any tool is avaiable to determine the root cause of the Status 24 Failure. Help would be highly appriciated
