db_FLISTsend failed: network read failed (42) - How to fix this one?

I have a monster backup that is about 600 Gigs, and seems to work about twice a year....The latest error is

 

db_FLISTsend failed: network read failed (42) 

 

Now reading http://www.symantec.com/business/support/index?page=content&id=TECH56033 This seems to suggest an issue between the media server and the master server.  Now what to do when these are on the same server?

 

I added another media server yesterday whilst this was in the middle of its backup, could this be a problem?

    bpimagelist.exe -idonly -d 11/01/2011 -policy grub-bak_san

    Use level 9 for infinity and keep the rest (10-24) for customized levels (e.g. 5 years, 7 years, etc...)

    This look like a timing issue. Set CLIENT_READ_TIMEOUT on both the client and master/media server to 3600 (1 hour). Re-try the operation.

    Have kicked it off again - It will take 3 days.  Ill let you know How it goes, going sooo slowly at present.

     

    I also disabled open file support, as its backing up a drive snapshot

    Hope you have Checkpoint restart enabled in the policy!

    You did not mention OS or NBU version? Have a look at this TN and see if it is relevant to your environment:

    http://www.symantec.com/docs/TECH154382

     

    You can also try to split the filesystem into different streams, e.g.

    NEW_STREAM
    X:\folder\folder1
    X:\folder\folder2
    NEW_STREAM
    X:\folder\folder3
    X:\folder\folder4
    X:\folder\folder5
    NEW_STREAM
    X:\folder\folder6
    .....

    in conjunction with Allow Multiple Data Streams in the policy attributes.

    This will give you an additional level of checkpoint restart. Reading 2 streams (or more) at the same speed as the single stream will get backups to run twice as fast as single stream.

    We have seen a customer's F&P data backing up in a couple of hours running 4 streams. Previously it ran from Friday night into Monday morning.

    I suppose there millions of files placed on the drive. Target is snapshot drive, so you can use raw partition backup for it. Consider other options listed below.

    • Raw partition backup with normal(MS-Windows) policy
      You can get better performance.But by this way, you can not restore individual files/folders from raw partition backup.
    • Raw partition backup with FlashBackup-Windows policy
      This required Enterprise Client license. With FlashBackup, you can restore individual files/folders from raw partition backup.

    Marrianne's multi-streaming suggestion is useful if you can assign multiple streams(jobs) from storage unit for this backup.

    Windows Server 2003 - Netbackup v7 - backing up a 3 SAN drives that are mounted at backup time. Windows sees them as local drives.

    Argh failed again - This time with three streams.  But only the monthly that I started manually. The weekly ran just fine, how very odd.

    Right now I really need to convert the retention of the successful weekly backup into a "infinite" like level 24.

    I have been using bpimagelist and I can find the three streams listed, but I need to find the backupid !

    of these three images so that I can feed it too:bpexpdate -recalculate -d date_time |-ret retention_level [-backupid backup_id]
     
    I have searched the command reference for windows, but cannot find a command that will list a backupid's? They are not in activity monitor

    Fantastic:
     
    C:\Documents and Settings\adm-cuttinn>bpimagelist -idonly -d 11/01/2011 -policy grub-bak_san
    Time:      20/11/2011 20:37:46   ID: grub-bak_1321821466   FULL (0)
    Time:      19/11/2011 03:47:15   ID: grub-bak_1321674435   FULL (0)
    Time:      19/11/2011 03:47:14   ID: grub-bak_1321674434   FULL (0)
     
    C:\Documents and Settings\adm-cuttinn>bpexpdate -recalculate -ret 9 -backupid grub-bak_1321821466
    Are you SURE you want to recalculate expiration dates on all images
    that meet the following criteria:
      backupid         grub-bak_1321821466
      retention will be changed to 9(infinity)
     
    Continue?(y/n)y
