Exchange server backup using ESEbcli2 API - Error in HrESEBackupSetup function with BACKUP_TYPE_LOGS_ONLY   

Hi,
   I am using ESEbcli2 API to take exchange server database backup.
When I use \'HrESEBackupSetup\' function with backup type
\'BACKUP_TYPE_FULL\' it succeeds and I am performing Full backup.
After that I am trying to use same function with backup type
\'BACKUP_TYPE_LOGS_ONLY\' it fails though previously I had perform
Full backup. Why it behaves so?

I have check database file header it shows like ...

Previous Full Backup:
        Log Gen: 0-0 (0x0-0x0)
           Mark: (0x0,0,0)
           Mark: 00/00/1900 00:00:00

Current Incremental Backup:
        Log Gen: 0-0 (0x0-0x0)
           Mark: (0x0,0,0)
           Mark: 00/00/1900 00:00:00

Current Full Backup:
        Log Gen: 0-0 (0x0-0x0)
           Mark: (0x0,0,0)
           Mark: 00/00/1900 00:00:00

Current snapshot backup:
        Log Gen: 0-0 (0x0-0x0)
           Mark: (0x0,0,0)
           Mark: 00/00/1900 00:00:00

Does after full backup, in database file header the Full backup flag
get set? or in which style?

Thanks,
Shyam
