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 backup of a database 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 ISAM tables. It runs
on Unix, and as of MySQL 4.0.18 also on 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:
· --help, -?
Display a help message and exit.
· --allowold
Do not abort if target exists (rename it by adding an _old suffix).
· --checkpoint=db_name.tbl_name
Insert checkpoint entries into the specified db_name.tbl_name.
· --debug
Enable debug output.
· --dryrun, -n
Report actions without performing them.
· --flushlog
Flush logs after all tables are locked.
· --keepold
Do not delete previous (renamed) target when done.
· --method=command
Method for copy (cp or scp).
· --noindices
Do not include full index files in the backup. This makes the backup
smaller and faster. The indexes can be reconstructed later with
myisamchk -rq for MyISAM tables or isamchk -rq for ISAM tables.
· --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.
· --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.
· --regexp=expr
Copy all databases with names matching the given regular expression.
· --socket=path, -S path
The Unix socket file to use for the connection.
· --suffix=str
The suffix for names of copied databases.
· --tmpdir=path
The temporary directory (instead of /tmp).
· --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:
shell> perldoc mysqlhotcopy
