Auto named files in multi-file backup have different names

When I split up backups into multiple files, sometimes not all of the files will get the same name... the seconds portion of the filename will be different. This is probably when the seconds portion of the time is different between generation of the names for the files.

Is it possible to use <AUTO> in a multi-file backup and get the same filename for all of the files? I can of course pre-generate the file names, but I like using <AUTO>.

Thanks!

    What is the <AUTO> definition that you are currently using? Could you also please provide the backup command that you are using?

    Thanks.

    Backup command splitting over 20 files:

    EXECUTE master..sqlbackup '-SQL "BACKUP DATABASE [DATABASENAME] TO DISK = ''F:\SQLBackups\<AUTO>_01.sqb'', DISK = ''F:\SQLBackups\<AUTO>_02.sqb'', DISK = ''F:\SQLBackups\<AUTO>_03.sqb'', DISK = ''F:\SQLBackups\<AUTO>_04.sqb'', DISK = ''F:\SQLBackups\<AUTO>_05.sqb'', DISK = ''F:\SQLBackups\<AUTO>_06.sqb'', DISK = ''F:\SQLBackups\<AUTO>_07.sqb'', DISK = ''F:\SQLBackups\<AUTO>_08.sqb'', DISK = ''F:\SQLBackups\<AUTO>_09.sqb'', DISK = ''F:\SQLBackups\<AUTO>_10.sqb'', DISK = ''F:\SQLBackups\<AUTO>_11.sqb'', DISK = ''F:\SQLBackups\<AUTO>_12.sqb'', DISK = ''F:\SQLBackups\<AUTO>_13.sqb'', DISK = ''F:\SQLBackups\<AUTO>_14.sqb'', DISK = ''F:\SQLBackups\<AUTO>_15.sqb'', DISK = ''F:\SQLBackups\<AUTO>_16.sqb'', DISK = ''F:\SQLBackups\<AUTO>_17.sqb'', DISK = ''F:\SQLBackups\<AUTO>_18.sqb'', DISK = ''F:\SQLBackups\<AUTO>_19.sqb'', DISK = ''F:\SQLBackups\<AUTO>_20.sqb'' WITH ERASEFILES = 1b, DISKRETRYINTERVAL = 30, DISKRETRYCOUNT = 10, COMPRESSION = 0, VERIFY, CHECKSUM"', @exitcode OUT, @sqlerrorcode OUT

    Here is a sample set of files generated from that:

    FULL_(local)_DATABASENAME_20120807_023000_14.sqb
    FULL_(local)_DATABASENAME_20120807_023000_15.sqb
    FULL_(local)_DATABASENAME_20120807_023000_16.sqb
    FULL_(local)_DATABASENAME_20120807_023000_17.sqb
    FULL_(local)_DATABASENAME_20120807_023000_18.sqb
    FULL_(local)_DATABASENAME_20120807_023000_19.sqb
    FULL_(local)_DATABASENAME_20120807_023000_20.sqb
    FULL_(local)_DATABASENAME_20120807_023001_01.sqb
    FULL_(local)_DATABASENAME_20120807_023001_02.sqb
    FULL_(local)_DATABASENAME_20120807_023001_03.sqb
    FULL_(local)_DATABASENAME_20120807_023001_04.sqb
    FULL_(local)_DATABASENAME_20120807_023001_05.sqb
    FULL_(local)_DATABASENAME_20120807_023001_06.sqb
    FULL_(local)_DATABASENAME_20120807_023001_07.sqb
    FULL_(local)_DATABASENAME_20120807_023001_08.sqb
    FULL_(local)_DATABASENAME_20120807_023001_09.sqb
    FULL_(local)_DATABASENAME_20120807_023001_10.sqb
    FULL_(local)_DATABASENAME_20120807_023001_11.sqb
    FULL_(local)_DATABASENAME_20120807_023001_12.sqb
    FULL_(local)_DATABASENAME_20120807_023001_13.sqb

    File name format (this is the default):

    <TYPE>_<INSTANCE>_<DATABASE>_<DATETIME yyyymmdd_hhnnss>

    I can remove the seconds portion from the <AUTO> but the same thing could happen when crossing to a new minute.

    Thanks for the help!

    I'm afraid there isn't a way to get the timestamp value to be identical for all files using your syntax. Since all the files are going into the same folder, you could use the FILECOUNT option instead, which will get you the same timestamp value, and also the sequential numbering you want e.g.
    EXECUTE master..sqlbackup '-SQL "BACKUP DATABASE &#91;DATABASENAME&#93; TO DISK = ''F:\SQLBackups\&lt;AUTO&gt;.sqb'' WITH FILECOUNT = 20, ERASEFILES = 1b, DISKRETRYINTERVAL = 30, DISKRETRYCOUNT = 10, COMPRESSION = 0, VERIFY, CHECKSUM"', @exitcode OUT, @sqlerrorcode OUT
