# Create a backup from a member of GR group , which at later point can be restored successfully.
#
# 0. Start GR on with 2 servers
# 1. Perform some DDL/DML operations on a member
# 2. Verify if the available backup (binlog file) can be later restored successfully on a non-member
# 3. Verify if that non-member can then be added to the GR group
# 4. Perform some DDL/DML operations to the group
# 5. Check mysqlbinlog output to test View Change Log events are written properly.
# 6. Cleanup
