netbackup client failing on daily incremental but ok on the weekly fulls

Hi all,

 

I have a bit strange backup problem the backup running find for weekly full but not on the daily incremental. Bellow is the message from the screen.

The version all thes asam Netbackup Enterprise 7.5.0.2. Master is RedHat 6.1, Media Sever is HPUX 11 v2 and the client is Solaris10 (actully similar thing also happened to windows, hpux client going the the same media server)

 

Any solution?

 

The problem Daily Incremental Backup:

the backup then stucked for the long time

At the end for the Daily

At the end for the Daily Incremental actually error status 40, but definitely not really because of the network, since the Weekly Full backup running from the same client and same media server running fine.

BTW I have also restarted the media server several times, but it no help for the Daily Incremental.

Can you see if bpbrm and bptm

Can you see if bpbrm and bptm processes are started on the media server?

Please check that these log folders exist on the media server.
Copy log files to reflect process name (e.g. bpbrm.txt) and post as File attachments.

If have seen this before.

If have seen this before. First try to set CLIENT_READ_TIMEOUT = 3600 in bp.conf on the media server and client. The daily backup is failing because it encounter a directory with a huge amount of files. Every files need to be eveulated for backup and this causes the timeout. The full does not evaluate - every file is in scope. Do you also see Error = 62 timer expired" in the job details ?

You can debug where the directory is using this  procedure found at : http://www.symantec.com/docs/TECH143355

To view the last file / directory where the backup is hanging, do the following on the client:

1. Create the bpbkar debug log directory by running mkdir /<install_path>/netbackup/logs/bpbkar. Generated log information will be placed in this directory in a file named log.mmddyy (where mm = month, dd = date, yy = year).
2. Create a file named touch /<install_path>/netbackup/bpbkar_path_tr to enable extended ../netbackup/logs/bpbkar/* debug logging
3. Enable verbose 5 client logging through the NetBackup GUI on the master.
       Under NetBackup Management>Host Properties>CLIENTS>double click client-name >properties>Logging>Global>5
       Or add  ' VERBOSE = 5 '  into the   /usr/openv/netbackup/bp.conf   file on the client server 
4. No restart needed is needed after these settings are added
5. Run a backup to generate the log information

Note that the use of this "touch" file 'bpbkar_path_tr'  will cause larger bpbkar logs than the usual.

Run command to start the test
  # cd /usr/openv/netbackup/bin
  # ./bpbkar -dt 0 -r 888 -nocont   /YOUR-DATA-PATH-TO-TEST-HERE    > /dev/null 
    
    If BPBKAR command stops or hangs, view the end of the /usr/openv/netbackup/logs/bpbkar/log.<date> file for the last file name and possible OS messages.

Before I posted the log. I

Before I posted the log. I should tell , the Daily incremental backup was running for months fine. Then suddenly happens, other backups like Weekly full.  Daily full, database agent are running fine till now.

I think it is not the directory with lots of files problem since all the client have quite small amount of files  (like bellow 1000) and it is not affecting one particular client, almost all clients (Windows, Linux, solaris) on that media server, and during certain times suddenly the backup running fine, then suddenly hang again. BTW this one also happened on other media server, it happened for several days then it is OK by itself.   I believe it is something to do with the media server or the tape?
