+@cindex backing up files
+@item --backups=@var{backups}
+Before (over)writing a file, back up an existing file by adding a
+@samp{.1} suffix (@samp{_1} on VMS) to the file name. Such backup
+files are rotated to @samp{.2}, @samp{.3}, and so on, up to
+@var{backups} (and lost beyond that).

Note that @samp{-c} only works with @sc{ftp} servers and with @sc{http}
servers that support the @code{Range} header.

+@cindex start position
+@item --start-pos=@var{OFFSET}
+Start downloading at zero-based position @var{OFFSET}. Offset may be expressed
+in bytes, kilobytes with the `k' suffix, or megabytes with the `m' suffix, etc.
+
+@samp{--start-pos} has higher precedence over @samp{--continue}. When
+@samp{--start-pos} and @samp{--continue} are both specified, wget will emit a
+warning then proceed as if @samp{--continue} was absent.
+
+Server support for continued download is required, otherwise @samp{--start-pos}
+cannot help. See @samp{-c} for details.

match those from the remote file. This allows the use of

@cindex SSL protocol, choose
@item --secure-protocol=@var{protocol}
Choose the secure protocol to be used. Legal values are @samp{auto},

+is used, the SSL library is given the liberty of choosing the appropriate
protocol automatically, which is achieved by sending an SSLv2 greeting
and announcing support for SSLv3 and TLSv1. This is the default.
Specifying @samp{SSLv2}, @samp{SSLv3}, or @samp{TLSv1} forces the use
of the corresponding protocol. This is useful when talking to old and

+SSL library to choose the correct protocol version. Fortunately, such
+servers are quite rare.
+
+Specifying @samp{PFS} enforces the use of the so-called Perfect Forward
+Security cipher suites. In short, PFS adds security by creating a one-time
+key for each SSL connection. It has a bit more CPU impact on client and server.
+We use known to be secure ciphers (e.g. no MD4) and the TLS protocol.

option, or set @code{passive_ftp=off} in your init file.

@samp{]}, appear in an element of @var{acclist} or @var{rejlist},
it will be treated as a pattern, rather than a suffix.
+In this case, you have to enclose the pattern into quotes to prevent
+your shell from expanding it, like in @samp{-A "*.mp3"} or @samp{-A '*.mp3'}.
@item --accept-regex @var{urlregex}
@itemx --reject-regex @var{urlregex}
Specify a regular expression to accept or reject the complete URL.
+@item --regex-type @var{regextype}
+Specify the regular expression type. Possible types are @samp{posix} or
+@samp{pcre}. Note that to be able to use @samp{pcre} type, wget has to be
+compiled with libpcre support.
+
@item -D @var{domain-list}
@itemx --domains=@var{domain-list}
Set domains to be followed. @var{domain-list} is a comma-separated list
Ignore case when matching files and directories. This influences the
behavior of -R, -A, -I, and -X options, as well as globbing
implemented when downloading from FTP sites. For example, with this
-option, @samp{-A *.txt} will match @samp{file1.txt}, but also
+option, @samp{-A "*.txt"} will match @samp{file1.txt}, but also
@samp{file2.TXT}, @samp{file3.TxT}, and so on.
+The quotes in the example are to prevent the shell from expanding the
+pattern.
@item -H
@itemx --span-hosts
Enable/disable saving pre-converted files with the suffix
@samp{.orig}---the same as @samp{-K} (which enables it).
-@c @item backups = @var{number}
-@c #### Document me!
-@c
+@item backups = @var{number}
+Use up to @var{number} backups for a file. Backups are rotated by
+adding an incremental counter that starts at @samp{1}. The default is
+@samp{0}.

@item base = @var{string}
Consider relative @sc{url}s in input files (specified via the
@samp{input} command or the @samp{--input-file}/@samp{-i} option,
