MARIADB-HOTCOPY(1) MariaDB Database System MARIADB-HOTCOPY(1)
mariadb-hotcopy - a database backup program (mariadb-hotcopy is
now a symlink to mariadb-hotcopy)
mariadb-hotcopy arguments
mariadb-hotcopy 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.
mariadb-hotcopy works only for backing up MyISAM and ARCHIVE
tables. It runs on Unix and NetWare.
To use mariadb-hotcopy, 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> mariadb-hotcopy db_name [/path/to/new_directory]
shell> mariadb-hotcopy db_name_1 ... db_name_n /path/to/new_directory
Back up tables in the given database that match a regular
expression:
shell> mariadb-hotcopy db_name./regex/
The regular expression for the table name can be negated by
prefixing it with a tilde (“~”):
shell> mariadb-hotcopy db_name./~regex/
mariadb-hotcopy supports the following options, which can be
specified on the command line or in the [mariadb-hotcopy] 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 mariadbd operates.
The path value should match that of the --chroot option given
to mariadbd.
• --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.
Use perldoc for additional mariadb-hotcopy documentation,
including information about the structure of the tables needed for
the --checkpoint and --record_log_pos options:
shell> perldoc mariadb-hotcopy
