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 

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

How to BACK UP the NetWorker Management Console (NMC)

How to BACK UP the NetWorker Management Console (NMC):

We can backup NMC through command line as well as GUI method.

First we will see the command line method:

Open the command line interface and run the command “savepsm” which will backup the NMC database. The normal Networker “save” command cannot back up NMC database successfully if it is open during backup hence it is always better to use "Savepsm" command.

Now we will see using GUI method:

Login to NMC console

Go to SETUP

Click the SETUP button on the toolbar

Select “Set Database Backup Server”

 Mention the NetWorker server name that you want to back up the NMC database.

Check "Create client resource on this server".

Set Client name to the hostname of the machine that has the NMC database.

Click OK.

After successfully configuration connect to the NetWorker server. When you look at the list of clients, you will get there a new client.

You will also see that client configuration saveset name starting with "NMCASA:/gst_on_NMC-Server-name/lgto_gst" with Backup Command attribute: savepsm (for a Windows Console server) or savepsm.sh(for a UNIX Console server).

You should verify the backup which you configured after successful first backup with mminfo command.

On Windows: mminfo -avot -s (NetWorker server) | find /i "gst"

On UNIX: mminfo -avot -s (NetWorker server) | grep -i gst

This are the method you can use to backup your NMC database.

NSR peer information' provided did not match

NSR peer information' provided did not match

nsrexecd GSS critical An authentication request from backupclient.com  was denied

If you experience errors in the backup server daemon log such as this:

89879 07/04/14 04:04:13  nsrexecd GSS critical An authentication request from backupclient.com  was denied. The 'NSR peer information' provided did not match the one stored by backupserevr. To accept this request, delete the 'NSR peer information' resource with the following attributes from backupserevr's NSRLA database: name: backupclient.com; NW instance ID: XXXXXXXX-XXXXXXXX-XXXXXXXX-XXXXXXXX-XXXXXXXX-XXXXXXXX; peer hostname: backupclient.com

It is because a client has been re-installed, renamed or the NSRLADB has been rebuilt.

To resolve this, delete the NSR peer information for the client on the backup server.

For example:

# nsradmin -p nsrexecd

NetWorker administration program.

Use the "help" command for help, "visual" for full-screen mode.

nsradmin> . type:NSR peer information;name:backupclient.com

Current query set

nsradmin> delete

                        type: NSR peer information;

               administrator: "isroot,host= backupserevr ",

                              "isroot,host=backupserevr.com",

                              "user=root,host=localhost";

                        name: backupclient.com;

               peer hostname: backupclient.com;

          Change certificate: ;

    certificate file to load: ;

How to recover the Clone Save Set

How to test cloned save set recovery
How to test single file cloned recovery

We have two Networker Sites and Two Data Domain Sites

Networker1 : 

Data Domain 1 : Backup of Networker1 is stored on DD1 and Cloning to DD2

Data Domain 2 : Disaster Site DD 

We have data on both Sites.

But for testing we have to restore cloned save set (e.g from DD2 only single file daemon.raw file)

Backup Data Domain Volume: DD1Volume.AA
Clone Data Domain Volume:   DD2CloneVolume.BB

In this scenario  you should run first normal recovery like as below:

bash-4.1$ sudo recover -c backuptest.com -R backuptest.com -iR

Current working directory is /

recover> cd /nsr/logs  (Check your files path)

recover> add daemon.raw

1 file(s) marked for recovery

recover> volume

Volumes needed (all on-line):

        DD1Volume.AA at rd=storagenode01.backuptest.com:DD1DISK01

recover>

But above volume is belong to DD1 not Cloned DD2.

Go to following path:

Login NMC >>> Backup Server >>> Media  >>> Disk Voulumes >>> DD1Volume.AA

For single file you cannot find there SSID you can find SSID for whole save set.

Then run recover again with same procedure like above.

bash-4.1$ sudo recover -c backuptest.com -R backuptest.com -iR

Current working directory is /

recover> cd /nsr/logs  (Check your files path)

recover> add daemon.raw

1 file(s) marked for recovery

recover> volume

Volumes needed (all on-line):

        DD2CloneVolume.BB at rd=storagenode02.backuptest.com:DD2DISK01

And recovered on same server on E:\ drive

recover> relocate

6479:recover: <return> will recover files into their original location

New destination directory: E:\restored_11-11-2015

recover> recover

After Test recover is completed you can revert the changes:

 Login NMC >>> Backup Server >>> Media  >>> Disk Voulumes >>> DD1Volume.AA and mark save set from suspect to Normal.

If you want to recover whole save set like “/” you can find the SSID and Clone ID using mminfo command.

bash-4.1$ mminfo -q client=backuptest.com-ot -r "client,name,volume,sscreate,ssretent,ssid,cloneid"

client                   Save Set name         volume               created        ssid          clone id

backuptest.com      /                      DD1Volume.AA          12/02/2015 123456789  1111111111

backuptest.com     /                      DD2CloneVolume.BB   12/02/2015 123456789  2222222222

recover> recover -S 123456789/2222222222

How to recover expired save set

• I am going to explain how to recover the expired save set or How to recover expired EMC Networker Data  or How to make Expired Save Sets to browsable for particular save set:

• Note:  If the browse and retention policy for the saveset has expired and the tape has been reused, you will be unable to recover the contents of the Saveset.

• Backup Software : EMC Networker

I will provide details as below scenario:

• Today Date : 12/05/2013

• Client want to restore data : 06/12/2013

• Browse/Retention Policy: Three month only

When I tried to browse the date 06/12/2013 with changetime command.

recover> changetime 06/12/2013

18360:recover: cannot browse /P/USER/ZZZZ55/docs/Outlook/ as of `06/12/2013 23:59:59' (mm/dd/yyyy)

recover>

Note: Need to follow below step to find the Index Tape related to that date,               ran mminfo to find the ssid of the index save set I'm looking for.

mminfo -r "name,savetime(17),ssid,cloneid,volume,location,level,ssretent" -q "client=Backup Server,name=index:client Name,savetime>06/01/13,savetime<06/30/13" -ot

name            savetime(17)      ssid     cloneid    level    volume      location    ssretent sumflags

index:BackupClient   6/12/2013   62433892   1371148564 full   11103L5      IBM3310      9/4/2013  cE

cE : E indicate Expired Save set

Make tape not recyclable as well as extend the expire time by Type -S and -o manully on command line:

nsrmm -S <ssid/CloneID> -e <new expiration date> ( DD/MM/YYYY )

nsrmm -S <ssid/CloneID> -o notrecyclable

nsrmm –S 62433892/1371148564  –e 12/12/2013

nsrmm –S 62433892/1371148564   –o notrecyclable

mminfo -r "name,savetime(17),ssid,cloneid,level,volume,location,ssretent,sumflags" -q "client=BackupServer,name=index:BackupClient,savetime>06/01/13,savetime<06/30/13" -ot

name   savetime(17) ssid cloneid    level  volume  location ssretent sumflags

index:BackupClient  6/12/2013  62433892 1371148564  full  11103L5  IBM3310  12/12/2013  cr

Cr : r indicate recoverable save set

State changed from cE to Cr Expired to recoverable and Expire date now changed from 09/04/2013 to 12/12/2013.

Then tried to rebuild index now.

nsrck -L7 -t MM/DD/YYYY <clientname> /  nsrck -v -L7 -t MM/DD/YYYY <clientname>

nsrck -t 06/12/13 -L7 BackupClient

recover> changetime 06/12/2013

18360:recover: cannot browse /P/USER/ZZZZ55/docs/Outlook/ as of `06/12/2013 23:59:59' (mm/dd/yyyy)

recover>

But we are getting same cannot browse error

Then search Data Tape and mark as recoverable and not recyclable and rebuild index.

mminfo -s BackupServer -r "client,name,savetime,ssid,cloneid,volume,location,ssretent,sumflags,level" -q "client=BackupClient,savetime>06/01/2013,savetime<06/30/2013" -ot | grep full

tr : r indicate recoverable save set

State changed from hE, tE to hr, tr Expired to recoverable and Expire date now changed from 09/04/2013 to 12/12/2013.

Then again try to rebuild indexes:

nsrck -L7 -t MM/DD/YYYY <clientname> /  nsrck -v -L7 -t MM/DD/YYYY <clientname>

nsrck -t 06/12/13 -L7 BackupClient
