  if ((err = adns_synchronous(my_adns_state, "www.cs.jhu.edu", adns_r_a,
                              adns_qf_cname_loose, &answer)) != 0)
    exit(fprintf(stderr, "adns_synchronous failed: %s\n",
strerror(err)));

  if (answer->status != 0)
    exit(fprintf(stderr, "query failure: %s\n",
adns_strerror(answer->status)));

Which prints out the following error:

query failure: DNS alias found where canonical name wanted

In case you have ssh access to your server or hosting accoung, also work with large mysql databases

$ mysqldump -h localhost -u username -p database_name > backup_db.sql

In case your database is very large, you may want to compress database

$ mysqldump -u username -h localhost -p database_name | gzip -9 > backup_db.sql.gz
