Steps to restore 2nd and 3rd copies of image from a different media server

Created: 10 Dec 2012 • Updated: 13 Feb 2013 | 20 comments
This issue has been solved. See solution.

Hi all,

Need some clarification regarding my NBU backup architecture, please see below:

I have a,

1. Primary Copy - Located on Primary Site MSDP (NBU Master Server) 

2. 2nd Copy - Located on Offsite MSDP (NBU Media Server B)

3. 3rd Copy - Located Offsite as well - Tape Out (LTO4) (NBU Media Server B)

I wanted to test restoration from the Tape Media which is my 3rd copy. Can you guys help how to do this?

Thanks a lot!

There is documented technote on how to do it. You need to set the copy which you want to restore as primary copy. Using GUI seemed as a better option.

http://www.symantec.com/docs/TECH64592

Please check and let us know if you have any questions or issues on it.

Extract from it

Via the GUI:

1. Go to the Catalog section of the GUI.
2. Select 'verify' and the top right the copy number of the current image you wish to use.
3. For the Date/Time Range From: value, enter the Start Date: used in the Backup, Archive and Restore GUI
4. For the Date/Time Range To: value, enter the End Date: used in the Backup, Archive and Restore GUI
5. Click Search Now
6. Right click on image you wish to restore from and click 'Set primary copy'.
Now when you go back to Restore GUI you can restore as normal and it will default to this copy

you just need to make your 3rd copy as a primary copy .. and trigger the restore..

it will automatically pick the data from the 3rd copy as it is a primary copy..

to make the 3 rd copy as primary copy..

Netbackup GUI--> catalog ..> select copy as 3 and provide client name and required dates..

it will list you the all avalaible copy 3 images , and right click on the required image and select "set as primary" 

then trigger the restore for the data that is on image that you set copy3 as primary copy from BAR window.

hope this helps..

Hi Nagalla/Deepak,

Thanks for the info. But another thing I want to clarify is can I bring the Tape Media (Copy 3) on the primary site? Can it be done? Because my problem is that I have a 450Gb data on a 20mbps wan link, if the Tape Media (3rd copy) cannot be brought to the Priamry site then it'll take ages to restore the files.

Deepak G's picture

When you make an copy as primary copy the information gets updated on the netbackup EMM database. So you dont have to move them manually to any sites.

Since you took data to disk it would have been faster and when you recover them from LTO4 media's it will be much slower.

If you just wanted to test the alternate copy restore, you can try it from second copy which is on the MSDP.

ericmagallanes,
 
 
do you have media server in remote site?
are you using Remote media server to make the copy 3 ?
 
if yes, 
you have the answer for your question "But another thing I want to clarify is can I bring the Tape Media (Copy 3) on the primary site? Can it be done? Because my problem is that I have a 450Gb data on a 20mbps wan link, if the Tape Media (3rd copy) cannot be brought to the Priamry site then it'll take ages to restore the files."
 
when you bring the tape media (3rd copy) to primary site, you need to use alternate media server restore
 
for that you need to use the FORSE RESTORE option.. once you bring the tape to Primary site..
 
check the below tech note for details.. 
 
http://www.symantec.com/business/support/index?page=content&id=TECH7582
 
hope this helps..

Easier solution:

1. Use bprestore with '-copy #'

2. Create ALT_RESTORE_COPY_NUMBER touch file in netbackup folder on master server. Put copy number to restore from in this file.

See http://www.symantec.com/docs/TECH64592 for details.

Hi All,

Thanks for your valuable comments, actually my approach is that I will be having a different retention periods on all the copies. Like 1st copy will have 2 weeks retention, 2nd copy 1 month retention, and say 1 year for 3rd copy.

So when 1st and 2nd copy expires I will use the 3rd copy to restore to my Primary site and will need to bring the Tape Media to the Primary site itself. I will try this technote as suggested by Nagalla http://www.symantec.com/business/support/index?page=content&id=TECH7582 and let you guys know.

Thanks a lot..

hi,

did you check , the media server that you are using have the dirves for the same robot , that was actaully used for backup.(duplicataion)

what is the media server that you are using?

please provide the tpconifg -d and vmoprcmd -d outputs from the media server

and also for vmquery -m <mediaid>

it would help to compare the Drives avaliablity..

Marianne's picture

Please show us output of the following:

nbemmcmd -listmedia -mediaid 0004L4 

as well as output of the following on the media server at the primary site that needs to perform the restore:

tpconfig -l.

You need to ensure that the same density drives are available that matches media density.

Per Mariannes' earlier post:

You need to ensure that the same density drives are available that matches media density.

From your output:

root@PRUXBK11:/ #nbemmcmd -listmedia -mediaid 0004L4
....
Media Type:                     HCART

and

root@PRUXBK11:/usr/openv/volmgr/bin #./tpconfig -l
...
  drive    -    1 hcart2    1      UP  -          IBM.ULT3580-HH5.000  /dev/rmt1.1
  drive    -    2 hcart2    2      UP  -          IBM.ULT3580-HH5.001  /dev/rmt2.1
...
  drive    -    3 hcart2    1      UP  -          IBM.ULT3580-TD5.000  /dev/rmt3.1
  drive    -    4 hcart2    2      UP  -          IBM.ULT3580-TD5.001  /dev/rmt4.1
  drive    -    7 hcart2    3      UP  -          IBM.ULT3580-TD5.014  /dev/rmt7.1
  drive    -    8 hcart2    4      UP  -          IBM.ULT3580-TD5.015  /dev/rmt9.1
...
  drive    -    5 hcart2    1      UP  -          IBM.ULT3580-TD5.002  /dev/rmt5.1
  drive    -    6 hcart2    2      UP  -          IBM.ULT3580-TD5.003  /dev/rmt6.1
  drive    -    9 hcart2    4      UP  -          IBM.ULT3580-TD5.020  /dev/rmt10.1
  drive    -   10 hcart2    3      UP  -          IBM.ULT3580-TD5.021  /dev/rmt8.1

....so no HCART drives hence the error: NBU status: 830, EMM status: No drives are available

Now we know 0004L4 is LTO4 (type HCART), but what are your drives? Could be LTO2 or LTO5 - hopefully the latter & you'll be able to change (temporarily) the designation to allow the restore.

Marianne's picture

If restore media is LTO4 and tape drives are LTO5, change one of the tape drives in robot where tape is to hcart.

...BUT....

The tape is in robot 8.
You gave us device output of robot 0, 1 and 2.

Which media server have access to robot 8?
Have you changed media ownership? Or added Force_Restore_Media entry?

Media 'belongs' to PRUXBK11_bk. Restore requests will be sent to that media server by default - unless you have done 'something' to send restore request to another media server.

Hi Andy/Marianne,

The Drive I am using for restore now is LTO5(Primary Site) and the previous drive we have is LTO4(Off Site).

Can you please let me know how to change it temporarily to HCART I am running NBU 7.5.0.3?

Also, the tape now is in Robot 0 and the Media Server that has a current access to the tape is PRUXBK11_bk. I also did add the  Force_Restore_Media entry on the bp.conf and changes media ownership as well.

Thanks..

Andy Welburn's picture

You could use tpconfig but probably easier to use the GUI - double-click or right-click>change the drive under Media & Device Management>Devices>Drives (will prompt to restart service).

I managed to change the type to HCART, but when I tried to update volume I got this error:

Did you move the tapes to 'Standalone' after removing it from original robot?

Easiest is to change device properties in the GUI. Else, use tpconfig (text-based menu) to select a drive and change density. Else, all-in-one command: 'tpconfig -update -drive <index-number> -type <drvtype>'

Hi guys,

Thanks for your help, this Technote solved my problem.

http://www.symantec.com/business/support/index?page=content&id=TECH6344&profileURL=https%3A%2F%2Fsymaccount-profile.symantec.com%2FSSO%2Findex.jsp%3FssoID%3D1355843919625eQ5XN3HPmHWh13qA839qCtrxbcTHV2JoXXKQ9

I did the ff:

1. Start the NetBackup Administration GUI.

2. Go to Media and select the Media ID(s) that need to be moved.

3. Go to Actions > Move and click Volume is in a robotic library.

4. Run Inventory and initiate restore.

Thanks a lot guys!..
