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 ARCHIVE tables. It
runs on Unix and NetWare.
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.
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 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.
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, and the RELOAD privilege (to
be able to execute FLUSH TABLES).
Use perldoc for additional mysqlhotcopy documentation,
including information about the structure of the tables
needed for the --checkpoint and --record_log_pos options:
shell> perldoc mysqlhotcopy
