  • Exchange 2003 Differential backup using ntbackup.exe fails


    I'm trying to do a remote backup of Exchange 2003 hosted on a Windows 2003 server, using ntbackup.exe. Full backup works flawlessly, but Differential backups fail. I tried to run a Differential backup on the Exchange 2003 server itself, but it still failed with Event IDs 8001 and 8019 errors. The backup log itself shows the below:

    Backup Status
    Operation: Backup
    Active backup destination: File
    Media name: "xchange2diff.bkf created 1/18/2007 at 12:53 PM"

    Volume shadow copy creation: Attempt 1.
    Backup of "XCHANGE2\Microsoft Information Store\First Storage Group"
    Backup set #1 on media #1
    Backup description: "Set created 1/18/2007 at 12:53 PM"
    Media name: "xchange2diff.bkf created 1/18/2007 at 12:53 PM"

    Backup Type: Differential

    Backup started on 1/18/2007 at 12:53 PM.
    The 'Microsoft Information Store' returned 'Some log or patch files are missing.

    ' from a call to 'HrESEBackupOpenFile()' additional data 'E:\Program Files\Exchsrvr\mdbdata\E000001F.log'
    The operation was ended.
    Backup completed on 1/18/2007 at 12:53 PM.
    Directories: 0
    Files: 2
    Bytes: 10,485,956
    Time: 2 seconds


    The operation did not successfully complete.

    I checked "VSSADMIN LIST WRITERS" and it shows the below output for Exchange Writer:
    Writer name: 'Microsoft Exchange Writer'
    Writer Id: {76fe1ac4-15f7-4bcd-987e-8e1acb462fb7}
    Writer Instance Id: {9f04e97e-512f-4fd0-8fbd-b4ec106b2152}
    State: [1] Stable
    Last error: No error

    I googled the error and many say that I should face this error if I'm trying to backup "system state" along with "Exchange IS", but this is not the case with me. I'm only trying to backup the Information Store.

    PS: Circular loggin is not enabled. But HKLM\system\currentcontrolset\services\MSExchangeI S\ParametersSystem\Circular Logging has a value of "1". !!!!!!!!

    How many logs you have?
    I would sugget to do the followings:
    1. Make a full backup - and verify !!!!!! that it is OK (make it twice).
    2. Dismount the DB (and logs will commit to the DB - so you will not loose any data).
    3. Still when the DB is dismounted, cut the logs and put them in a temp folder (anywhere - but not in their original location).
    4. mount the DB.
    5. Make a full backup.
    6. Try Differential backup.
