I have used the command line :
snapshot-create-as --diskspec vda,snapshot=external,file=/u4/guest/MaBa- clone/test.snap.img--domain MaBa-clone --name MaBa-clone_snap --description "Snap before 9Aug2020"
I believe that when creating an external snapshot, you have to either specify --disk-only (to not snapshot RAM), or supply --memspec (to specify how/where to save RAM).
