MYSQLHOTCOPY(1) MySQL Database System MYSQLHOTCOPY(1)
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 LOCK TABLES, FLUSH TABLES, and cp or
scp to make a database backup quickly. It is the fastest 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 ISAM tables, and ARCHIVE tables as
of MySQL 4.1. mysqlhotcopy runs on Unix, and also on NetWare as of
MySQL 4.0.18.
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:
o --help, -?
Display a help message and exit.
o --addtodest
Do not rename target directory (if it exists); merely add files to
it. This option was added in MySQL 4.0.13.
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. This
option was added in MySQL 4.0.19.
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 hostname 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).
o --noindices
Do not include full index files in the backup. This makes the backup
smaller and faster. The indexes for reloaded tables can be
reconstructed later with myisamchk -rq for MyISAM tables or isamchk
-rq for ISAM tables.
o --password=password, -ppassword
The password to use when connecting to the server. Note that the
password value is not optional for this option, unlike for other
MySQL programs. You can use an option file to avoid giving the
password on the command line.
Specifying a password on the command line should be considered
insecure. See Section 7.6, "Keeping Your Password Secure".
o --port=port_num, -P port_num
The TCP/IP port number to use when connecting to the local server.
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 the connection.
o --suffix=str
The suffix for names of copied databases.
o --tmpdir=path
The temporary directory. The default is /tmp.
o --user=user_name, -u user_name
The MySQL username to use when connecting to the server.
mysqlhotcopy reads the [client] and [mysqlhotcopy] option groups from
option files.
To execute mysqlhotcopy, you must have 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).

information about the structure of the tables needed for the
--checkpoint and --record_log_pos options:
shell> perldoc mysqlhotcopy
