How to recover

1. Note down the client id of the clients required from the source location.
2. On the second location, create dummy clients with those names and those client IDs. You can just make a dummy entry in hosts file to create the dummy client. Before clicking ok when you create the client, paste the client id for this client that you noted from the source setup.
3. scan the tapes using scanner -i \\.\tape0 in the new setup.
4. Once indexes and media entry are recovered, you can open NEtworker User and recover the data.

If you want to restore to another client using the same backup server, you need to use the relocated recover. This can be done using the gui or using the recover command with the -R flag.

If you are restoring using a different backup server, you would need to use the scanner command. You can do a saveset level restore by using scanner -S if you know the ssid or use scanner command to identify the ssid first then use scanner -S.

If you want to do a browsable recover using another backup server, use scanner -i to rebuild the index for the tape you are trying to restore from. Please note that if you are trying to restore from multiple tapes, you will need to run scanner -i on each of the tapes before you can do a browsable restore from them.

HI Anuj , i given the client ID which the networker specified and default the different ID which is there in the old client ID , This problem got resolved , I want to know how to scan the device for the recovery . Kindly give me the details if possible as soon as possible . Waiting for your reply .


Rajesh

As you said i tried to give the client ID , It throws an error like randomly it takes different Client ID and asked me to give this generated client ID , or change the client Name . What can i do now .


Rajesh

For scanning the tapes, scanner is the command to be used.

Run scanner -i \\.\tape0 with tape mounted in tape0. -i scans and recovers the media entry along with index entries form this tape. You can use scanner -m \\.\tape0 which will recover only the media entry. Use either based on your requirement. -i recovers indexes thereby making Recovery easier.

What you mean by tape is Drive 0 rite .Actallu if i tried to mount in the drive , it showing an error like not in media Index .

If using NW you should load it with nomount option or via jukebox panel or sjimm.

It can't do that due to different clientid. A find a bit strange that you can't use old cid on new server - that has never happened to me (yet). You may wish to engage your support and have them connect remotely to verify your steps and have this troubleshooted further.

HI,
If i given the old client ID, the NW is not taking and it takes a diffrerent one , And as you said , I mounted and scanned , In the nwrecover , i can see the index but throws an error while recovering like canoot find volume . And if i clicked in the recover save sets , it shows an error message like volume not present , But the volume is in the drive . Reply me ASAP .

Hrvoje Crvelin ,

Ok, Just let me know what are the steps to recover , Kindly tell me from your point of view ,
What i did is ,
Created the new same group name and the same client name and the save sets and all the parameters are same .And copied the index file from \nsr\index to the new server \nsr\index . Then ,
Mounted the tapes in the drive and in the command prompt , typed scanner -m \dev\nst1, and scanner -i \dev\nst1 . Then it took the index files , In the Nwrecover , I can see the index files , But if i tried to restore it shows like volume not found . This happens in Recover files , While in recover save sets , it shows no volume with the name . But the drive is in the drive only .

Just let me know , if there is any problem i made or what should i do to overcome this problem , I need to resolve this issue within today because implemeting remotely .

Anuj :
As you said , Kindly let me know how to give old CLient ID in the new NW'r . Kindly let me know as soon as possible .

Hi Anuj,
As you said , i can see the volume name in the media - volume and i done the unmount and mounted it again , no error i got , but If i tried in nwrecover i am getting like ,
recovering 84707 files within /t5/ into /t5
Total estimated disk space needed for recover is 65 GB.
Requesting 84707 file(s), this may take a while...
53365:recover: NSR server `vzutlix11.tmindia.tatamotors.com': Cannot find the volume needed

5766:recover: waiting 30 seconds then retrying
53365:recover: NSR server `vzutlix11.tmindia.tatamotors.com': Cannot find the volume needed

5766:recover: waiting 30 seconds then retrying


Here the vzutlix11.tmindia.tatamotors.com' is the new Networker server and the t5 is the group in the old nw'r . Kindly le me know what should i do .

Your scanner output shows, scanner has worked fine. Check for the entry of this volume under Media->Volumes. It should be there now.

The tape was mounted in the drive manually...unmount it manually i.e. from library control panel. After getting it in a slot, perform NW inventory for the slot. It should then show the tape in View->Volumes while recoveries. If using a standlone device, mount the volume through NW and check.

To give old client ID in new NW server, Go to Configurations->Clients->New...enter the hostname...go to the client Id field and type the old client id before click at OK/Apply. If this hostname is not there in the environment, you can make an entry in /etc/hosts file for this host to get identified. This should be the first time you are creating a client with this hostname.

You shouldn't have copied index as scanner would do that. You also do not run first -m and then -i but rather -i right away. By running -m your mdb will known index is expired so second time you run -i it won't work unless you change mdb record. I would suggest you involve your support - you said initially this was urgent so at this point you wish this to be done without much theorizing on forums.
