+\fBmysqlhotcopy \fR\fB\fIarguments\fR\fR
+.SH "DESCRIPTION"
+.PP
+\fBmysqlhotcopy\fR
+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 database backup 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.
+\fBmysqlhotcopy\fR
+works only for backing up
+MyISAM
+and
+ARCHIVE
+tables. It runs on Unix and NetWare.

+.sp
+Display a help message and exit.
+.TP 3n
+\(bu
+\fB\-\-addtodest\fR
+.sp
+Do not rename target directory (if it exists); merely add files to it.
+.TP 3n
+\(bu
+\fB\-\-allowold\fR
+.sp
+Do not abort if a target exists; rename it by adding an
+_old
+suffix.
+.TP 3n
+\(bu
+\fB\-\-checkpoint=\fR\fB\fIdb_name\fR\fR\fB.\fR\fB\fItbl_name\fR\fR
+.sp
+Insert checkpoint entries into the specified database
+\fIdb_name\fR
+and table
+\fItbl_name\fR.
+.TP 3n
+\(bu
+\fB\-\-chroot=\fR\fB\fIpath\fR\fR
+.sp
+Base directory of the
+\fBchroot\fR
+jail in which
+\fBmysqld\fR
+operates. The
+\fIpath\fR
+value should match that of the
+\fB\-\-chroot\fR
+option given to
+\fBmysqld\fR.
+.TP 3n
+\(bu
+\fB\-\-debug\fR
+.sp
+Enable debug output.
+.TP 3n
+\(bu
+\fB\-\-dryrun\fR,
+\fB\-n\fR
+.sp
+Report actions without performing them.
+.TP 3n
+\(bu
+\fB\-\-flushlog\fR
+.sp
+Flush logs after all tables are locked.
+.TP 3n
+\(bu
+\fB\-\-host=\fR\fB\fIhost_name\fR\fR,
+\fB\-h \fR\fB\fIhost_name\fR\fR
+.sp
+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.
+.TP 3n
+\(bu
+\fB\-\-keepold\fR
+.sp
+Do not delete previous (renamed) target when done.
+.TP 3n
+\(bu
+\fB\-\-method=\fR\fB\fIcommand\fR\fR
+.sp
+The method for copying files (cp
+or
+scp).
+.TP 3n
+\(bu
+\fB\-\-noindices\fR
+.sp
+Do not include full index files in the backup. This makes the backup smaller and faster. The indexes for reloaded tables can be reconstructed later with
+\fBmyisamchk \-rq\fR.
+.TP 3n
+\(bu
+\fB\-\-password=\fR\fB\fIpassword\fR\fR,
+\fB\-p\fR\fB\fIpassword\fR\fR
+.sp
+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. You can use an option file to avoid giving the password on the command line.
+.sp
+Specifying a password on the command line should be considered insecure. See
