What are the differences between a full LUN copy and an incremental LUN copy?

6

Both copy data from the source LUN to target LUNs. Their difference is:
Full LUN copy: It copies all data from the source LUN to target LUNs each time.
Incremental LUN copy: When it is started for the first time, it requires an initial synchronization during which all data is copied from the source LUN to target LUNs. For subsequent times, it copies only the changed data from the source LUN to target LUNs.
