a database backup program
add an example, a script, a trick and tips
mysqlhotcopy --method=scp --user=<your_user>--password='your_password' db_name./table_name/ root@<Remote_server_ip>:/home/backup/mysql_backup
##What does it do ?
It will take the hot backup of only particular table which will be mentioned above. This is an effective method to take the backup as only one table will be locked and rest of the table will be available to users.
scp will automatically store the backup on the remote server or we can call the backup server.
Flushed 1 tables with read lock (`db_name`.`table_name`) in 0 seconds.
Locked 0 views () in 0 seconds.
Copying 3 files...
mysqlhotcopy copied 1 tables (3 files) in 4 seconds (4 seconds overall).

is a Perl script that was originally written and contributed
by Tim Bunce. It uses FLUSH TABLES, LOCK TABLES, and cp or
scp to make a database backup. It is a fast way to make a
backup of the database or single tables, but it can be run
only on the same machine where the database directories are
located. mysqlhotcopy works only for backing up
MyISAM and ARCHIVE tables. It runs on Unix.
mysqlhotcopy, you must have read access to the files
for the tables that you are backing up, the SELECT privilege
for those tables, the RELOAD privilege (to be able to
execute FLUSH TABLES), and the LOCK TABLES privilege (to be
able to lock the tables).

of the local host to use for making a TCP/IP connection to
the local server. By default, the connection is made to
localhost using a Unix socket file.

The method for
copying files (cp or scp). The default is cp.
Do not include
full index files for MyISAM tables in the backup. This makes
the backup smaller and faster. The indexes for reloaded
tables can be reconstructed later with myisamchk

optional for this option, unlike for other MySQL
password on the command line should be considered insecure.
See Section 18.104.22.168, “End-User Guidelines for
Password Security”. You can use an option file to
avoid giving the password on the command line.

As of MySQL
5.5.3, mysqlhotcopy uses FLUSH TABLES tbl_list
WITH READ LOCK to flush and lock tables. Use the
--old_server option if the server is
older than 5.5.3, which is when that statement was
introduced. This option was added in MySQL 5.5.3.
