Backup Failure: Operating system error 64

  • Hello,

    I am having a problem creating backups for a database.  I am using the Backup Task in SSIS and executing the SSIS package against a SQL Server 2000 database.  Sometimes the backup is successful, but recently the failure rate has increased with the following messages listed in the log:

    [Execute SQL Task] Error: Executing the query "BACKUP DATABASE [Galaxy]

    TO  DISK = N'\\mindata02\Data_D\DEVSQL6\Galaxy\Galaxy_backup_200706070927.bak'

    WITH NOFORMAT, NOINIT,  NAME = N'Galaxy_backup_20070607092724', SKIP, REWIND, NOUNLOAD, 

    STATS = 10 " failed with the following error: "BACKUP DATABASE is terminating abnormally. 10 percent backed up.

    20 percent backed up. 30 percent backed up. 40 percent backed up. 50 percent backed up. 60 percent backed up.

    70 percent backed up. 80 percent backed up. 90 percent backed up. Processed 4503024 pages for database

    'Galaxy', file 'Galaxy_Data' on file 1. Processed 9360 pages for database 'Galaxy', file 'Galaxy_IDX' on file 1.

    100 percent backed up. Processed 59228 pages for database 'Galaxy', file 'Galaxy_Log' on file 1.".

    Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly,

    or connection not established correctly.

    Operating system error 64(The specified network name is no longer available.).

    If anyone has encountered the Operating System Error 64(The specified network name is no longer available) or Operating System Error 59(An unexpected network error arrived) and has some recommendations it would be greatly appreciated.  Thanks in advance for the help.


    Kindest Regards,


  • From the error message it is clear there is a netwroking problem.   Are you able to ping server where you are backing to ?

  • Yea, I am able to successfully ping the server.  The odd thing is that it is successful at times, it just takes numerous attempts.  I was hoping that there was a patch released by Microsoft or a setting/configuration that needs to be correctly set to address this issue, but have not come across anything yet.  Any recommendations would be greatly appreciated. 

    Kindest Regards,

  • Are you running named Pipes protocol? This could be a named pipes issue.

  • Did you solve this issue?

    I am having the same problem and was wondering what your solution was.


  • kindly share your backup location and error while backup and use a new forum to post new queries..
