The linux kernel exposes the the acls of files via the extended attribute system.cifs_acl (see fs/cifs/xattr.c for all attributes). It seems impossible to backup those with gnu tar. I tried
tar --xattrs -xattrs-include=system.cifs_acl -cvf /target /source1

The issue seems that these extended attributes are "virtual"
getfattr -d -m ".*" filename
won't show that those attributes are available, but
getfattr -n system.cifs_acl filename
will show them. So you need to know their name.
