EMC NetWorker backup logs files paths and details for Unix/Linux

Hi,

Today here I would like to provide details of the log files available on a Unix Net-worker server and log

file management.

Networker Server Log Files:-

Networker Server Log Files:-

Networker Client Log files:-

There is two types of logs files:


*.log >> It is plan text file and human readable
*.raw>> It is not human readable format


You can view manually raw files with help of nsr_render_log Networker command.
You can also set it in runtime with help of nsradmin and "update runtime rendered log" Networker configuration commands.


The nsr_render_log send the output result to stdout


You can also rollover the files by time and size with help of below commands:


nsradmin
update runtime rollover by time
update runtime rollover by size


Thanks

How to Delete VBA Node in Networker

How to Delete VBA Node in Networker

Networker Ver: 8 to 9

If you want to remove VBA node entirely and delete it's backups from Networker server. The VBA node is online and responding to request from Networker server. Before Doing anything please consult with EMC Support for Assistance because VBA Node delete/remove is not recommended by EMC as a troubleshooting step.

Before starting any critical configuration you should take first backup of nsrdb and mm directories (Particular directory which related with that configuration)

Connect to Networker backup server and open the following directory

 <networker-install>\nsr

e.g   

·         Unix: /nsr/ 

·         Windows C:\Program Files\EMC NetWorker)

Make a copy of the following directories:

res\nsrdb

res\mm

After successfully copied mentioned directories you can start your actual configuration.

Remove all save sets for the client-id for this VBA node

List the Saveset:

mminfo  –c  <vba-name>  -kot

Remove Saveset:

nsrmm -d -S <SSID>

If the VBA is NOT online, then use the -X option to delete the Save set:

nsrmm -X -d -S <SSID>

Remove all workflows associated with the VBA and Delete VBA Mtree

Using GUI (NMC):

1. Login to NMC

2. Go to Configuration tab and click VMware Protection Policies

3. Sort the policies by VBA List

4. Open the first policy that has this VBA listed, go to VMware Backup Appliance Selection      tab and uncheck the VBA name.

5. Wait for the State column to change to Success

Using CLI (nsradmin):

nsradmin> p type: nsr hypervisor; name: <vcenter-name>

nsradmin> Delete

Remove VBA server resource using nsradmin

 d type: NSR VBA Server; name: <vba>

Note: This step may need to be done using offline nsradmin if VBA is NOT responding

Delete the VBA Appliance Delete the relevant VBA node VM from the vCenter server

On the NetWorker server, run nsradmin command utility to find the VBA DPN ID:

nsradmin> show name

nsradmin> show DPN ID

nsradmin> p type: nsr vba server; name: VBA-FQDN

To delete the storage unit on Data Domain:

Login to Data Domain as Admin and run command,

ddboost storage-unit delete <storage-unit>

Clean file system if required using command, filesys clean start

If the External proxy is no longer needed delete the external proxy virtual machine

How to check validcopies in NetWorker 9 with mminfo

How to check validcopies in NetWorker 9 with mminfo:

In your backup environment data clone going to a disk media, I suspect that we are rarely will see a save set with clflg mminfo attributes. The reason is that 'faulty/aborted' save sets will automatically be deleted.

If you want to know whether a save set has successfully been cloned you better check with 'validcopies' mminfo attribute:


mminfo -r "client,name,ssid,validcopies,pool"

or to verify all save sets with only one copy

mminfo -q "validcopies<2" -r "client,name,ssid,validcopies,pool"

Browse and retention time raised Script for multiple SSID

Today I would like to explain How Browse and retention time period extend by Script for multiple SSID

bash-$ mminfo -avot -q "savetime>=02/01/2016,savetime<=03/31/2016" -r client,ssid,group,ssbrowse,ssretent >ssid.txt 2>&1

Select the respective SSID which need to extend and put in to one text file ssid-re.txt. After that run the below script for extend the Browse and retention period;

Today Date : 04/01/2016

bash-$ for i in `cat ssid-re.txt`; do sudo nsrmm -S $i -e "6 months" -y; done

bash-$ for i in `cat ssid-re.txt`; do sudo nsrmm -S $i -w "6 months" -y; done

You will get the error browse time should be less than retention time.

You should mention commands like as 

for i in `cat ssid-re.txt`; do sudo nsrmm -S $i -w "Sun Feb 28 06:16:05 2016" -y; done

After extended the both policy verify it.

for i in `cat verifyssid.txt`; do mminfo -q ssid=$i -r 'client,ssid,sscreate,ssbrowse,ssretent' >>output.txt; done 

EMC ELECT 2016

Friends I would like to share that I am elected as EMC Elect 2016 with another 70 experts from 150 finalists.

Below is the link for your reference to see the list of elected candidates

https://community.emc.com/community/connect/emc_elect/blog/2016/01/31/the-emc-elect-of-2016--the-official-list

This is a very funny incident with me about EMC elect. When I started working on EMC product and I heard from someone that there is one kind of election EMCElect. I was very surprised because I thought EMC is also conducting election like politicians  but after reading about EMC Elect I got to know that this is an honor for EMC expertise.

So that time I was very excited to grab much information about EMC Elect. I always share my knowledge regularly on EMC Community Network, sharing on Twitter too. I also started sharing my technical tips through blogs and on EMC community forum for knowledge sharing.

I was shortlisted For EMC ELECT 2013 but was not selected, and I took it as a challenge and I said to myself that next time I will take more efforts and again participate in 2014 and finally I got first EMC honor in 2014 and again in 2016.

I would like to thanks all who voted me and fulfil to complete this program.

This is unique initiative by EMC and I am really enjoying to participate year again year.

Special thanks to Mark Browne ‏@DathBrun and all known unknown people who were involved in this activity.

VSS System Writer is not found on this system

The VSS System Writer is not found on this system:

While backing up Windows 2008 and 2012 server on EMC Networker and you are getting below error, there will be many causes for this error. This is a very common permission issue.

98266:save: The VSS System Writer is not found on this system.  The backup is stopping because the System Writer is required for a successful system state backup.  Have the system administrator check the VSS infrastructure and fix the issue.

You should first try below solution:

Start or Restart below services:

1. COM+ Event System

2. COM+ System Application

3. Distributed Transactions Coordinator

4. Microsoft Software Shadow Copy Provider

5. Volume Shadow Copy service

6. Networker remote exec service

And try to take test backup, if it fails again then you should go with below Microsoft solution.

The system writer fails because permissions to files in the %windir%\winsxs\filemaps\ or %windir%\winsxs\temp\PendingRenames directories are incorrect.

Solution:

To resolve this issue, type the following commands from an elevated command prompt:

Takeown /f %windir%\winsxs\temp\PendingRenames /a
icacls %windir%\winsxs\temp\PendingRenames /grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\temp\PendingRenames /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\temp\PendingRenames /grant BUILTIN\Users:(RX)
Takeown /f %windir%\winsxs\filemaps\* /a
icacls %windir%\winsxs\filemaps\*.* /grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\filemaps\*.* /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\filemaps\*.* /grant BUILTIN\Users:(RX)

net stop cryptsvc
net start cryptsvc

Type the following command to verify that the system writer is now listed: vssadmin list writers


If the system writer is missing, check the Application event log for the following event
