NAME¶
mysqlhotcopy - a database backup programSYNOPSIS¶
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 and NetWare. 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
shell> mysqlhotcopy db_name./regex/
shell> mysqlhotcopy db_name./~regex/
•--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=path
Base directory of the chroot jail in which mysqld operates. The
path 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.
•--old-server
Connect to old MySQL-server (before v5.5) which doesn't have FLUSH TABLES WITH
READ LOCK fully implemented..
•--password=password,
-p password
The password to use when connecting to the server. The password value is not
optional for this option, unlike for other MariaDB programs.
Specifying a password on the command line should be considered insecure. 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.
•--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 file 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=path
The temporary directory. The default is /tmp.
•--user=user_name, -u
user_name
The MariaDB 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
