Description:
MySQL Enterprise backup does not correctly restore server uuid.
IMHO server_uuid after restore should be automatically set back to the old value. That is at least the expected behaviour.
How to repeat:
+----------------+--------------------------------------+
| Variable_name | Value |
+----------------+--------------------------------------+
| server_uuid | 16a8bd0f-3632-11e7-991b-d0509970f88e |
+----------------+--------------------------------------+
./bin/mysqlbackup --user=root --backup-dir=/tmp/tape backup

# server_uuid=16a8bd0f-3632-11e7-991b-d0509970f88e
./bin/mysqlbackup --user=root --datadir=/home/mysql/data/mysql-5.7 --backup-dir=/tmp/tape copy-back

cat auto.cnf

server-uuid=a395c95c-3633-11e7-a1aa-d0509970f88e
Suggested fix:
Create auto.cnf from server_uuid
