DESCRIPTION
       vmbk.pl is a script for creating ESX disk snapshot.
       It supports disk copy to local host disk or remote Disk with NFS / SMB 
       vmbk can be used on guest powered or on  guest unpowered. 
       vmbk support batch and interactive use.	
       vmbk search about 'backup' option on vm guest definition file ,the option may have 3 value NONE,MANUAL,AUTO, if NONE no backup is possible, if MANUAL is possible only  interactive mode (-i option) , if AUTO backup is always done.
       If backup isn't finding, it's equivalent to AUTO.

OPTIONS
The long and short forms of options, shown here listed together, are equivalent.
    -h         
	    	Help about parameters
     -n	
	don't display start info

    -d 	directory        
	Exports the disk contents of the specified guest OS on the specified directory local or remote, to a VMware Workstation format virtual disk.
	The virtual disk may then be transferred to another machine and imported to a SCSI device on the remote machine. 
	The virtual disk will likely take less space then the full size of the VMFS file, since the virtual disk does not        
	include zeroed sectors of the disk image. When this option is used on a guest powered on an ESX Server REDO log is 	
	created, when the exported virtual disk is done the REDO log is commit to its base disk.
