restore with disaster recovery CD fails
Hi,
I run Legato networker V 7.6.4.5 on Win2008; also my clients run that version.
I have made a backup of the saveset DISASTER_RECOVERY:\ andf I have made a disaster recovery boot CD.
I have made the backup of the DISASTER_RECOVERY saveset to disk (adv_file).
Then I boot the client with the recovery CD and I enter the name, Ip settings, ... in the fields.... It shows me the legato servers when searching for (so my network connection is working as well)..... then I get the following error message:
Error retrieving the list of backups using no command option
Unknown error occured while trying to get the list of backups in NativeMethod_avGetBackupList(). Check the logfile for possible causes.
Where can I find the logfile ? In the Event Viewer of the Legato server, I don't see any relevant info.
Possible ideas how to proceed ?
Best regards,
Johan

Hello Johan,
There are a couple of places to check for your logs --
One is --
C:\Program Files\Legato\nsr\tmp\sg
This checks all groups that you have established -- and within each folder you will see sso.00000a -- files. Open this files up in Word pad to see what is happening with each client.
Then try the below location next --
C:\Program Files\Legato\nsr\logs ---
At the above location you will see the daemon.raw - this is a log file - you will have to make a copy this file and I always name the file with the date I am conducting research. If I were you I would open this file in wordpad to review everything that is happening within networker.
I hope this helps you with your investigation.

Hi,
I have looked into those files. But no relevant information there.....
What else can i do ?
- I have made the backup of the DISASTER_RECOVERY saveset to disk not to tape . But that should be OK. No ?
- I have not made a backup of the C: drive..... But that should be OK. No ?
- I could use the ALL save (that includes the DISASTER_RECOVERY saveset ....
Other ideas are more than welcome !
Rgds,
Johan

Are you trying to recovery to the same original machine or another machine?
If you are restoring to another machine, the hardware configuration of the target machine must be similar to the original machine.
You must also satisfy the following requirements for performing a directed recover:
– The NetWorker server must have a client resource for both the source machine and the target machine.
– The Remote Access attribute of the client resource for the source machine must allow access to the user / host machine that is performing the directed recovery operation. Do this by adding "SYSTEM@target_client" to the source client resource’s Remote Access attribute.
– Add "user=system,host=target_client" to the Users attribute of the NetWorker server’s preconfigured Administrators user group.
Note: If a different client (target) is specified, the restored machine will use the same hostname and IP settings as the source machine. This can cause hostname and IP address conflicts if the source machine is running on the same network.

Hi Tim,
I try to recover the original hardware (so identical)
I give in the same name as how it was backed up
There is a client resource for this one and the same client
In the remote acess field of that client there is: *@*
I have now added user=system,host=client resource to the users attribute on the Legato server in the Administrators group. So this is my only change
And in the logfield on the legato server there is aline:
Authentication warning: conflicting NSR peer information detected for host 'clientname'. Please see log information". For clientname i take a new clientn ame but existing as Legati client or the original clientname. I get this message in both cases.
IS THERE A CLEAR DOCUMENT DESCRIBING in detail the procedure of DISASTER_RECOVERY:\ and related troubleshooting ?
Rgds,
Johan

Hello JohanRM,
Yes there is a detailed DR guide, you will find the section in the Networker Admin Guide (Windows 2008 disaster recover or something similar). Among other things it describes how to turn off nsrauth for the client to be restored which will solve the authentication error for a start. As for the other error, the log files are actually automatically backed up to the server (usually end up in the Default pool) after the failed attempt. If you keep an eye on the server you should see them being saved. Once saved you can restore them somewhere for inspection.

Hi Johan,
I did not receive the thread notification because you edited the post instead of adding a new post.
Since it reports “conflicting NSR peer information”, you can refer to the following article to delete NSR peer information:
https://community.emc.com/docs/DOC-20085
You can refer to NetWorker Administration Guide (Support for Windows 2008/2008 R2/Windows 7 Disaster Recovery section) and Disaster Recovery Guide for detailed information about Disaster Recovery:
