Transferring backups

    My problem is that although full and transaction log backups are running beautifully using backup devices, I cannot work out how to copy the log files to another server from a scheduled sql agent job. I want to use the source file and destination as specified in the backup devices (sysdevices table).

    I found xp_cmdshell and knocked up the following stored procedure

    < ?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 

    CREATE PROCEDURE up_CopyBackup

    @Source                      varchar(100),

    @Dest             varchar(100)

    AS

    /*

    Copies file specified by backup device source to file specified by backup device dest

    */

    DECLARE @SourceDev         varchar(400)

    Declare @DestDev      varchar(400)

    Declare @SQLString   varchar(4000)

    Declare @rc                             int

    set @rc = 0

    SET NOCOUNT ON

    /*

    Get source and dest backup device details

    */

    select @sourcedev =  phyname from dbo.sysdevices where name = @source

    select @destdev = phyname from dbo.sysdevices where name = @dest

    set @SQLstring = 'copy ' + @sourcedev + ' ' + @destdev

     print @sqlstring

     

    exec @rc = xp_cmdshell @SQLString

     

    RETURN @rc

     

    I thought this would do it and set it up as a T_SQL jobstep, following the backup to device “Source” as

    exec up_CopyBackup ‘Source’, ‘Dest’

    but the copy failed to work, with the error “The system cannot find the file specified.”.

    But it has just successfully backed up to it!!

    I can also do a successful backup to the dest device from the job – I am temporarily doing full backups rather than tran logs to achieve the duplication.

     

    I am executing this from the agent account (a windows account) with sql system administrator rights on both servers.

    The source device is e:\dir and the dest is \\servername\e$\dir

     

    My sql version is (from print @@version)

    Microsoft SQL Server  2000 - 8.00.534 (Intel X86)

                Nov 19 2001 13:23:50

                Copyright (c) 1988-2000 Microsoft Corporation

                Standard Edition on Windows NT 5.0 (Build 2195: Service Pack 4)

     

    I then found an activeX script to copy files. This worked beautifully when I hard coded the file names but I really want to use the lookup in sysdevices as the backup device can then only be altered in one place not lots.

     

    1. Why didn’t the xp_cmdshell work when the backup and active X work with the same files?

    2. How can I do the lookup in activeX script?

    3. Can I write a parameterised stored procedure to do the job in ActiveX script and call it from T_SQL?

     

    I don’t want replication or log shipping, just backups available on the second server.

     

    Sorry this is so long but I wanted to explain fully. 

    Many thanks.

    Hi,

    What is the account with which SQL server(MSSQLSERVER ) is running. MSSQLSERVER must be running with a windows account which has got sufficient rights on the destination server. 

    Use

    exec master.dbo.xp_cmdshell N'xcopy e:\dir\*.dat  \\servername\e$\dir\'

    command do not mention the file name.
