Netbackup 7.5.0.4 and Exchange 2010 backup ( GRT )

Good Morning,

 

I'm trying to backup an Exchange server with GRT "option".

I follwed the istruction that i found here :http://www.symantec.com/connect/videos/exchange-2010-sp2-grt-netbackup-75

On Media server i stopped and disable the Server and Client NFS services

I execute the command " sc config portmap start= auto "

and i created the empty file No.Restricions under C:\Program Files\Veritas\Netbackup\db\altnames

On the Exchange server the client disable the Server NFS services.

I created the backup policy ( MS-Exchage Server ) and I "flag" Perform snapshot backup and Enable granula recovery.

I submitted the backup job and a first result is

Info bptm(pid=5716) using 32 data buffers        
22/01/2013 13:00:07 - Error bpbrm(pid=992) from client "clientname": ERR - Client for NFS service is either not installed or not running.
22/01/2013 13:00:09 - Info bptm(pid=5716) start backup          
22/01/2013 13:00:09 - Info bptm(pid=5716) backup child process is pid 5420.4608      
22/01/2013 13:00:09 - Info bptm(pid=5420) start           
22/01/2013 13:00:09 - begin writing
22/01/2013 13:00:24 - Error bpbrm(pid=992) from client "clientname"- Error encountered while attempting to get additional files for Microsoft Information Store:\clientname_MB_01_Do_Not_Use\Logs_1358855898\
22/01/2013 13:00:24 - Error bpbrm(pid=992) from client "clientname": ERR - Exchange granular restore from this image may not work.

 

So at this point where I wrong ?

I'm trying to backup on DataDomain

Many thanks

R.

    Sometimes worth setting a proxy host for restores (under client host properties for the exchange servers) - this would be you media server

    As it looks like that media server is an appliance then i guess the fragment size it writes to disk is the default at 25600 MB.

    To reduce the database system errors it is worth increasing the client read timeouts (to at least 1800) on the Media servers and also for GRT backups i like to use a smaller fragement size as it mounts smaller chunks of the backup images to do the restore - i like to use 5000MB which is a lot smaller than an appliances default

    Hope this helps

    We have just had a few issues with GRT and Exchange 2010. But before you get to solving issues make sure you have everything in place, try below articles: http://www.symantec.com/business/support/index?page=content&id=TECH187446 http://www.symantec.com/business/support/index?page=content&id=HOWTO73076 Also, GRT will not work with circular logging enabled, as we found out. See how you go.

    Hello aleco, i checked all points that you suggest in your pages. In the end the problem was that the client tried to solve the media server using the SQDN .. so we solved the problem inserting the DNS suffix. Unfortunately now, matser side i have another problem during the restore. If i try to explore the public folder i receive this error

    Ok - try the proxy host and the fragment size then - if you change the fragment size you will need another full backup first in order to test restores from that one

    Ok, i will try with the proxy host.. For fragment size is more complex.. The db in this moment is about 1 TB.. so it will be necessary about 5 Hours to perform another backup.. Stay tuned :-) !

    Hi all. I'm not a big expert, hence I had to log a case with Symantec support. We encountered an issue where after successful backup of Exchange 2010 DAG (with GRT or without) we were unable to get to the restored data. We could see it, but when we selected a backup and clicked ok we got an error. Our Master server is Redhat 6.3, after checking the logs we found the issue to be that the name of the DAG was referred to in lower case characters, where in the Java GUI it was in caps. To fix this we just linked one location to another using symbolic link. We found the following in the logs: 12:28:41.797 [10392] <2> DbmOdbcView::fetchChars: (.2) Fetched : client_name.corpad.net.local 12:28:41.797 [10392] <2> image_dir: ? 12:28:41.797 [10392] <2> image_dir_name: ? 12:28:41.797 [10392] <2> ImageListFiles::executeQuery: No images for client client_name.corpad.net.local if your Master server is Linux, check if you have the following: /usr/openv/netbackup/db/images/CLIENT_NAME /usr/openv/netbackup/db/images/client_name If your Master server is Windows, then I may not be able to assist you. Regards Alex

    Hello aleco many thanks for your suggestion but my media server is W2008 R2.

    The strange thing in this moment is that client side when we try to expand a single public forlder i saw , master side,always a restore process.
