Do you have a function similar to an an EMC cloneset?   Basicily a cloneset
tracks what has changed in both the source and target luns (drives).  When one
updates the cloneset the target is made identical to the source.  Its a great
way to do backups.  Its an important feature to be able to write to the target drives.
I would love to see this working at a filesystem level.

Thanks
