MYSQLHOTCOPY(1) MariaDB 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 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 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] option file groups. • --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, -ppassword 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.
