   I checked the docs, we don't say we do incremental/linked snapshots for KVM 
or have any other information for users - 
https://docs.cloudstack.apache.org/en/4.18.1.0/adminguide/storage.html#incremental-snapshots-and-backup
   
   I think full snapshots were slow but really effective, we need to revert the 
changes or at least make it configurable via some global setting (default set 
to full snapshots without any backing file for KVM volume snapshots).
   
   @weizhouapache yes, agree - I've confirmed with my testing above against ACS 
4.18.1.0 and Ubuntu 22.04 + local storage, welcome anybody to test/confirm the 
same with nfs and other storages (the behaviour is storage agnostic and may 
affect wide user community, and potential data loss like I incurred).
