NetBackup Basics and how to make YOUR life easier ...
This entry is intended to cover a number of issues that I see time and time again with members posting questions on the forum, and from my experience as a NBU TSE. The advice below is intended ... (1) To make your life easier (2) To assist in making a quicker resolutions (A) Command Issues *************** A common question - Where is the <command> I cannot find it ? The vast majorty of NetBackup binaries are located in the following directories, therfore by simple looking, you should find the command. You could also search, using the search feature in windows, or the find command in Unix. Unix/ Linux /usr/openv/netbackup/bin /usr/openv/netbackup/bin/support /usr/openv/netbackup/bin/admincmd /usr/openv/volmgr/bin There are also so 'scripts' available in /usr/openv/netbackup/bin/goodies Windows <install path>\veritas\netbackup\bin <install path>\veritas\netbackup\bin\support <install path>\veritas\netbackup\bin\admincmd <install path>\veritas\volmgr\bin There are also some 'scripts' available in <install path>\veritas\netbackup\bin\goodies It is even easier, if you add these paths to the PATH variable of the operating system. This allows you to run commands without having to type in the comlete path each time, or, cd to the directory. Unix: Add the directories to the PATH variable in the .profile file in the home directory of the user you log in as. For example ; PATH=$PATH:/usr/openv/netbackup/bin/admincmd:/usr/openv/netbackup/bin:/usr/openv /netbackup/bin/goodies:/usr/openv/netbackup/bin/support:/usr/openv/volmgr/bin:/u sr/openv/java:/netbackup:/opt/sfw/bin:/netbackup/scripts:/opt/VRTSaz/bin/vxazd:/ opt/VRTSat/bin/:/opt/VRTSaz/bin/:/opt/vormetric/mseo/server/bin:/opt/vormetric/m seo/agent/bin:/usr/openv/db/bin Windows: Add the directories the the PATH user variable (Right click computer, Properties, Advanced System Settings, Environment Variables (Path is under System variable ), For example. C:\Perl\site\bin;C:\Perl\bin;C:\Oracle\Ora92\bin;C:\Program Files\Oracle\jre\1.3.1\bin;C:\Program Files\Oracle\jre\1.1.8\bin;C:\Program Files\RSA SecurID Token Common;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Symantec\pcAnywhere\;C:\Program Files\QuickTime\QTSystem\;C:\Program Files\Enterprise Vault\EVClient\;C:\Program Files\Symantec\Workspace Virtualization\;C:\Program Files\Veritas\NetBackup\bin;C:\Program Files\Veritas\NetBackup\bin\admincmd (B) Insufficient information ************************ Starting a post with a question such as ... My media is getting frozon during a job, what do I do ? .. is virtually useless, EVERY post should be started with information simailar to these questions ... Initial Information recommended for all issues: 1. The exact error message (if an error is given) 2. During which type of operation does the problem occur ? For example, Backup, Duplication, Vault, Restore etc. 3. At what point in the job does the issue occur, for example, right at the beginning. 4. Which system(s) are involved? For example, Master Server, Media Server - Please provide system names. 5. Please submit the support report from the master and any relevant Media Servers in the environment. 6. Is this a reoccurring issue ? 7. What was the system doing at this time ? 8. Please send in the contents of the details tab in the Activity Monitor for the job. 9. What logs or screenshots are available? 10. Has this worked previously? If so, when was the last time it DID work? 11. Have there been any environmental; system; or configuration changes? 12. When did the problem begin? 13. How often does the problem occur? 14. Is a similar configuration working properly? (C) Is NetBackup the cause ********************** Many NetBackup issues, commonly, Tape/ Library issues and Networking issues are nothing to do with NBU, and the issue cannot be fixed through NetBackup commands. NetBackup often reports and issue, but is nothing to do with the cause. Consider this: If you uninstall NetBackup, what are you left with ??? Hopefully ... An operating system A network Storage devices, tape or disk So. straight away, it can been seen that that these three things are totally separate from NBU. Clearly there is 'interaction' between them, for example, tape drives are 'configured' in NetBackup after all, but NetBAckup does not control these and if the advice given is to investigate from a hardware perspective, or OS issue, this is exactly what needs to be done. In my experience, the majority of Network and Tape /Library issues have nothing to do with NetBackup, and the investigation should start with the vendor / network support. (D) NetBackup Engineers are not hardware engineers. If you have a hardware issue, speak to hardware type people ... (E) Document your system. Any backup environment should be documented, with the documents kept up-to-date. An excellent start to this is to run : nbsu -c -t every day and keep the outputs, (perhaps back them up to tape.) You will note I have not told you exactly where this command is, please see point (A). (F) Logs: On occassion, we will ask for logs ... See this technote, it contains everything you need to know. http://www.symantec.com/docs/TECH75805 When you send logs in, if the issue happens at say 15.00, we don't need the past weeks worth of logs, edit the log down so you send in for example, 14.30 - 16-00. (Note, sometimes the logs will be needed for a longer period, but usually / generally, the logs areound the time of the issue are fine). Also, please rename logs to the process name (NOT for the case of Unified logs (see technote above).) NetBackup defines different (legacy) logs simply by the folder name they are in, which isn't ideal. This means if we ask for say bptm and bpbrm log, both will have exactly the same filename (log.<date>). Please rename these to <process_name>.log.<date> ) The nbcplogs command is very good, it simplifies the collections of logs. Have a go at learning to use this command. http://www.symantec.com/docs/HOWTO43784 You should be able to set up logs without assistance, all that should be required is that we ask, pleased send bptm, bpbrm logs from the media server, or, please send vx logs 111, 116, 117, 118. You should automatically know that these should be gathered, probably with the verbose levels increased. (G) Every log sent in for a problem, must cover the same time period. It is no good sending in bptm from Monday and bpbrm from Tuesday, yes, people actually do this ... (H) If we ask for (example) bpmedialist -m <media id>, please DO NOT send the binary. Please run the command and send the output. I'm sure your binaries are very nice, but I have some of my own - thanks. (I) Our favorite question is "What changed". The usual answer is "Nothing has changed". Generally speaking, NBU does NOT break on it's own, 99% of the time, something HAS changed. I've not yet worked out if people just have no idea who is changeing what and when, or if they just deny making any changes - but if a change has been made, we will find it, it just may take considerable time, adding days or even weeks to the time it takes to resolve an issue. It's better to be truthful and say "I am not aware of any changes" than categorically deny that any changes have been made. (J) If you make a change, write it down somewhere (preferably in a change file on the system) - see (I) above (K) Backups fail, get used to this idea, it is part of being a backup administrator. Do NOT start making changes because of a single failure, this leads to broken systems. (L) If you make a change, and it does not fix the problem, revert it. DO NOT MAKE MULTIPLE CHANGES WITHOUT RECORDING THEM. It can be very very difficult to find an issue, if multiple changes have been made that cause the same symptoms. Consider this : I go home and the light does not work. (Unknown to me, the fuse is broken) I have three possibilities The light switch is broken The light bulb is broken The fuse is broken I decide to change the bulb, unfortunately the bulb I put in is also broken. (I have now introduced another 'fault' that gives the same symptoms as the originally fault). Next I change the fuse, but due to the broken buld, the light does not work. Unknown to me, I have now fixed the originally issue, but I cannot tell due to the faulty bulb fitted, So, from this example you can see how it is possoible to to completely break a system - avoid doing this. (M) NetBackup Engineers are not network engineers, if you have a network issue, go and talk to network type people (N) Just because NetBackup reports and error, DOES NOT mean it caused the error. This is particularly true for network, tape and library issues. (O) Read this - http://www.symantec.com/docs/TECH169477 If your systems/ issue fits a description in the technote, no matter how many times you ask, the answer will be the same. (P) Hardware vendors often blame NBU, especially when it comes to tape/ library issues. This is why the technote in (O) was written, to help prove that NBU is not at fault. (Q) Any backup system MUST be designed before being installed, else it WILL fail. Backup design does NOT start with pressing buttons, it starts with a peice of papaer and a pen. (R) If you want to know how to do something, try looking in the manuals.

(V) When you are asked to do steps 1, 2, 3, 4, 5 Please ensure you do ALL the steps, and not just the ones you feel like doing. We don't ask for the steps because we have nothing better to do, we ask for them because we need ALL of them. (W) Please do not make changes just because you can. Any change to a system should be fully justified, researched, and recorded accurately in the system documentation. The system documentation should be so detailed, it contains every change made and when, and the current setting of EVERYTHING that has been changed from the default- are you doing this ?

NetBackup Media Server Decommissioning Tool now for 6.5.3 to 7.0
Like to share and capture in the forum these recently published tools. These are being released to facilitate and I guess ease the task of decommissioning Netbackup media servers. (versions 6.5.3 • 6.5.4 • 6.5.5 • 6.5.6 • 7.0) Although the technotes already available are pretty straightforward, these tools/wizards seem to help identify areas throughout the NBU environment where you might be using references to the 'old server'.

Netbackup VMware Backup - Windows Change Journal
If I am backing up VMware VM's using the FLASHBACKUP-WINDOWS policy type, with an OFF-HOST VMware type of backup (VRAY), then I assume the use of Windows Change Journal on the VM itself is of no benefit ? Any comments ? I am using CBT for the VM's, and performing FULL & DIFFERENTIAL backups. I have 'lots' of files on this server, and am looking to get the shortestbackup window possible. I am using a VMware Mount Host which is SAN attached to the datastore LUNs of the ESX5 servers. NBU 7104. Any Comments ? AJ
HOW TO install BackupExec 2010 agent on Debian (RALUS)
I hope this post will be useful to many people (please vote for it or mark it as solution if it helps you). Installing directly RALUS on Debian will not always work. First problem : ../perl/Linux/bin/perl: No such file or directory Second problem : at the end "was not successfully installed" and "impossible to add VRTSralus to (server)" And some others that will get solved when following my solution This is a simple way to install it and avoid these (and other) problems : 1. (optional) Create a folder to keep all RALUS files and copy the archive into it : mkdir /root/BE mkdir /root/BE/RALUS2010 mv RALUS_RMALS_RAMS-2896.9.tar.gz /root/BE/RALUS2010/ cd /root/BE/RALUS2010 2. Unpack the archive provided by Symantec tar xzf RALUS_RMALS_RAMS-2896.9.tar.gz 3. Stop the RALUS service if it is already installed and runnig /etc/init.d/VRTSralus.init stop 4. Very important, if you are under a 64 bit Linux you have to this Extract debian package : tar xzf RALUS64/pkgs/Linux/VRTSralus.tar.gz Install debian package : dpkg -i VRTSralus-13.0.2896-0.x86_64.deb Start installation : ./RALUS64/installralus 5. But if you are under a 32 bit Linux you have to this (I didn't tested under 32 bits) : Extract debian package : tar xzf pkgs/Linux/VRTSralus.tar.gz Install debian package : VRTSralus-13.0.2896-0.i386.deb Start installation : ./RALUSx86/installralus or ./installralus 6. Be sure to answer all questions correctly especially the one about the host server (XXX.XXX.XXX.XXX), you must give the IP of the Backup Exec server. 7. Do a restart of the RALUS Backup Exec agent, and it should say "[ OK ]" /etc/init.d/VRTSralus.init start I hope it will help ! Send me questions if you have other problems... Denis P.S. Tested with Debian 5.0.3 P.P.S. If you still have some problems : A) If you get "ERROR: VXIF_HOME is invalid. It must point to the root of VxIF. Exiting ...", simply edit ./RALUS64/installralus, and change line 3 : from : VXIF_HOME=../;export VXIF_HOME to : VXIF_HOME=/root/BE/RALUS2010/;export VXIF_HOME B) If you get "./RALUS64/installralus: line 50: ../perl/Linux/bin/perl: No such file or directory", simply edit ./RALUS64/installralus, and change line 50 : from : ../perl/$OS/bin/perl -I.. -I$PATH -I$VXIF_HOME -I../perl/$OS/lib/$PERL_VER ../installralus.pl $* to : ../perl/$OS/bin/perl -I.. -I$PATH -I$VXIF_HOME -I../perl/$OS/lib/$PERL_VER ./installralus.pl $* or to : perl -I.. -I$PATH -I$VXIF_HOME ./installralus.pl $* (to be clear, remove one dot in front of"/installralus.pl", keep only one dot instead of two) C) If the installation is sucessful but VRTSralus refuses to start, launch /opt/VRTSralus/bin/beremote –-log-console to see the error. If you get error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory you simply need to install the package : Under Debian 6.0.3 : apt-get install libstdc++5 (Thanks to RockwellMuseum)
New in 7.7: The NETBACKUP LOGGING GUIDE!
One of the cooler things to come with our NetBackup 7.7 release is a brand new manual called the Logging Reference Guide - 155 pages of (hopefully) EVERYTHING you would need to know about how NetBackup logs, what logs, what logs WHERE, and how to use logs to troubleshoot your issues as well as what support's gonna ask you for if you end up opening a case with US. Our super Technical Publications team sought a lot of Engineering AND Support input to help make this manual the best it could be. Put this one on your summer reading list!
