Hi,

Preserve data: 

Data preservers

Sometimes, it is necessary to preserve some data on an instance targeted for cloning. For example, if the target is a MID Server, you must not overwrite the MID Server [ecc_agent] table. Preserved data is stored on the target instance before cloning begins and is restored on the target instance after cloning.

Exclude data:

Basically:

Preserve means: keep what data is already there on the target instance, but add to it.

Exclude means: If no preserve, don't even bring data to the target instance, but instead make it empty. Otherwise, if perserved, but excluded, then keep what is there, but don't touch it.

Here's a nice HI article as well: https://hi.service-now.com/kb_view.do?sysparm_article=KB0717012

Additionally, I've created a video to help you Master ServiceNow Cloning!

Hi,

The data in the tables specified in Exclude list are not cloned over to the target instances. The preservers retain any required data in your target instances like SSO, LDAP, mid server and similar data. Both these options work in a combination to produce the right clone results. 

Please refer to the last part of this video where I am explaining this feature in detail.
