a) Taking the full backup of all the tables including the data.
Use the following command to accomplish this:
mysqldump -u admin -p admin accounts > accounts.sql

b) Taking the backup of table structures only.
Use the following command to accomplish this:
mysqldump -u admin -p admin --no-data accounts > accounts.sql

c) Taking the backup data only.
Use the following command to accomplish this:
mysqldump -u admin -p admin --no-create-info accounts > accounts.sql

Restoring MySQL Database

Restoring the MySQL is very easy job. You can use the following to command to restore the accounts database from accounts.sql backup file.

mysql - u admin -p admin accounts < accounts.sql

Selain bisa digunakan membackup database ke file, mysqldump bisa juga membackup database ke database mysql di server lain. dengan perintah :
mysqldump –user admin –password=test –opt mydata | mysql –host=192.168.13.13 -C newmydata

Keterangan :
–opt : options ini berfungsi mengoptimalkan fungsing pembacaan database
–host : server tujuan tempat data base tujuan (di server tujuan sudah dibuat newmydata database terlebih dahulu)
-C : options ini berfungsi agar data di kompresi terlebih dahulu sebelum di kirim ke database tujuan

*** Can't find server name for address 192.168.3.254: Query refused
*** Default servers are not available
Default Server: UnKnown

caranya :

di /etc/named.caching-nameserver.conf ubah dari localhost menjadi any

view localhost_resolver {
# match-clients { localhost; };
# match-destinations { localhost; };
match-clients { any; };
match-destinations { any; };
recursion yes;
include "/etc/named.rfc1912.zones";
};

di /etc/named.rfc1912.zones

zone "3.168.192.in-addr.arpa" IN {
type master;
file "192.168.3.zone";
allow-update { none; };
allow-query { any; };
};

zone "azmy.co.id" IN {
type master;
file "db.azmy.info";
allow-update { none; };
allow-query { any; };
};

zone "qt.co.id" IN {
type master;
file "db.qt.azmy.info";
allow-update { none; };
allow-query { any; };
};

jika muncul seperti ini :

ganti di : /etc/named.caching-nameserver.conf

# allow-query { localhost; };
allow-query { any; };

edit file di etc : named.caching-nameserver.conf
tambahin
