You don't want to copy /dev/sda from a live system unless you've got some way of copying from a snapshot

You also do not want to copy partitions on gpt(GUID) partitioned drives. With gpt, the partition GUID is in the primary partition table, backup partition table & the partition. If they get out of sync, then you have major issues. new users really should not use dd and even as a bit more knowledgeable user I try to find any other way than dd.
