Backup Restore of configuration using parted

I have miscellaneous questions about parted.

I have an Itanium II machine using a GPT partitionning.
I change this partitionning using dd (a copy the first 256k of another disk)
When I reboot I have a kernel error message :
        sdb:<4>GPT:disk_guids don't match.
        GPT: Use GNU Parted to correct GPT errors
This error is perfectly normal: with dd I have changed the primary GPT 
partitioning but not the alternate/backup GPT partitionnig.
My question is : "Here is a parted command to repair these GPT errors ? Or do I 
need to rebuild GPT the partitionnig from scratch"

My second problem is : 
I tryed to make a script that reads the output of a "parted /dev/sdb print" 
command and recreates the same partitionning on another machine.
Can I recreate any partitionning ? 

For example here is a partitionning I created with fdisk
        Disk geometry for /dev/sdb: 0.000-34732.890 megabytes
        Disk label type: msdos
        Minor    Start       End     Type      Filesystem  Flags
        3          0.031   1749.265  primary               
        4       3482.842   4361.396  primary               

I there a set of commands to create this partitioning from parted ?

Thank you for your help
