NAME
mysqlhotcopy - a database backup program
SYNOPSIS
mysqlhotcopy arguments
DESCRIPTION
mysqlhotcopy 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.
To use 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).
shell> mysqlhotcopy db_name [/path/to/new_directory]
shell> mysqlhotcopy db_name_1 ... db_name_n /path/to/new_directory
Back up tables in the given database that match a regular
expression:
shell> mysqlhotcopy db_name./regex/
The regular expression for the table name can be negated by
prefixing it with a tilde ("~"):
shell> mysqlhotcopy db_name./~regex/
mysqlhotcopy supports the following options, which can be
specified on the command line or in the [mysqlhotcopy] and
[client] groups of an option file. For information about
option files, see Section 4.2.3.3, "Using Option Files".
o --help, -?
Display a help message and exit.
o --addtodest
Do not rename target directory (if it exists); merely
add files to it.
o --allowold
Do not abort if a target exists; rename it by adding an

_old suffix.
o --checkpoint=db_name.tbl_name
Insert checkpoint entries into the specified database
db_name and table tbl_name.
o --chroot=path
Base directory of the chroot jail in which mysqld
operates. The path value should match that of the
--chroot option given to mysqld.
o --debug
Enable debug output.
o --dryrun, -n
Report actions without performing them.
o --flushlog
Flush logs after all tables are locked.
o --host=host_name, -h host_name
The host name 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.
o --keepold
Do not delete previous (renamed) target when done.
o --method=command
The method for copying files (cp or scp). The default is
cp.
o --noindices
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 -rq.
o --password=password, -ppassword
The password to use when connecting to the server. The
password value is not optional for this option, unlike

MySQL Database System MYSQLHOTCOPY(1)
for other MySQL programs.
Specifying a password on the command line should be
considered insecure. See Section 6.1.2.1, "End-User
Guidelines for Password Security". You can use an option
file to avoid giving the password on the command line.
o --port=port_num, -P port_num
The TCP/IP port number to use when connecting to the
local server.
o --old_server
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.
o --quiet, -q
Be silent except for errors.
o --record_log_pos=db_name.tbl_name
Record master and slave status in the specified database
db_name and table tbl_name.
o --regexp=expr
Copy all databases with names that match the given
regular expression.
o --resetmaster
Reset the binary log after locking all the tables.
o --resetslave
Reset the master.info file after locking all the tables.
o --socket=path, -S path
The Unix socket file to use for connections to
localhost.
o --suffix=str
The suffix to use for names of copied databases.
o --tmpdir=path
MySQL 5.5 Last change: 03/22/2013 3
MySQL Database System MYSQLHOTCOPY(1)
The temporary directory. The default is /tmp.
o --user=user_name, -u user_name
The MySQL user name to use when connecting to the
server.

including information about the structure of the tables
needed for the --checkpoint and --record_log_pos options:
