NAME
mysqlhotcopy - a database backup program
SYNOPSIS
-
mysqlhotcopy arguments
DESCRIPTION
-
-
Note
-
- This utility is deprecated in MySQL 5.6.20 and removed in MySQL 5.7
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 used by MySQL programs, see
Section 4.2.6, lqUsing Option Filesrq.
-
*
--help,
-?
Display a help message and exit.
-
*
--addtodest
Do not rename target directory (if it exists); merely add files to it.
-
*
--allowold
Do not abort if a target exists; rename it by adding an
_old
suffix.
-
*
--checkpoint=db_name.tbl_name
Insert checkpoint entries into the specified database
db_name
and table
tbl_name.
-
*
--chroot=dir_name
Base directory of the
chroot
jail in which
mysqld
operates. The
dir_name
value should match that of the
--chroot
option given to
mysqld.
-
*
--debug
Enable debug output.
-
*
--dryrun,
-n
Report actions without performing them.
-
*
--flushlog
Flush logs after all tables are locked.
-
*
--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.
-
*
--keepold
Do not delete previous (renamed) target when done.
-
*
--method=command
The method for copying files (cp
or
scp). The default is
cp.
-
*
--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.
-
*
--password=password,
-ppassword
The password to use when connecting to the server. The password value is not optional for this option, unlike for other MySQL programs.
Specifying a password on the command line should be considered insecure. See
Section 6.1.2.1, lqEnd-User Guidelines for Password Securityrq. You can use an option file to avoid giving the password on the command line.
-
*
--port=port_num,
-P port_num
The TCP/IP port number to use when connecting to the local server.
-
*
--old_server
In MySQL 5.6,
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.
-
*
--quiet,
-q
Be silent except for errors.
-
*
--record_log_pos=db_name.tbl_name
Record master and slave status in the specified database
db_name
and table
tbl_name.
-
*
--regexp=expr
Copy all databases with names that match the given regular expression.
-
*
--resetmaster
Reset the binary log after locking all the tables.
-
*
--resetslave
Reset the master info repository file or table after locking all the tables.
-
*
--socket=path,
-S path
The Unix socket file to use for connections to
localhost.
-
*
--suffix=str
The suffix to use for names of copied databases.
-
*
--tmpdir=dir_name
The temporary directory. The default is
/tmp.
-
*
--user=user_name,
-u user_name
The MySQL user name to use when connecting to the server.
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
