renamed as each file is transferred or deleted. You can control where the
backup file goes and what (if any) suffix gets appended using the

-option will be enabled.
+
+Note that if you don't specify bf(--backup-dir), (1) the
+bf(--omit-dir-times) option will be implied, and (2) if bf(--delete) is
+also in effect (without bf(--delete-excluded)), rsync will add a protect
+filter-rule for the backup suffix to the end of all your existing excludes
+(e.g. -f "P *~"). This will prevent previously backed-up files from being

correctly and ends up corrupting the files.
-dit(bf(-x, --one-file-system)) This tells rsync not to cross filesystem
-boundaries when recursing. This is useful for transferring the
-contents of only one filesystem.
+dit(bf(-x, --one-file-system)) This tells rsync to avoid crossing a
+filesystem boundary when recursing. This does not limit the user's ability
+to specify items to copy from multiple filesystems, just rsync's recursion
+through the hierarchy of each directory that the user specified, and also
+the analogous recursion on the receiving side during deletion. Also keep
+in mind that rsync treats a "bind" mount to the same device as being on the
+same filesystem.
+
+If this option is repeated, rsync omits all mount-point directories from
+the copy. Otherwise, it includes an empty directory at each mount-point it
+encounters (using the attributes of the mounted directory because those of
+the underlying mount-point directory are inaccessible).
+
+If rsync has been told to collapse symlinks (via bf(--copy-links) or
+bf(--copy-unsafe-links)), a symlink to a directory on another device is
+treated like a mount-point. Symlinks to non-directories are unaffected
+by this option.

+updating files that do not exist yet on the destination. If this option is
+combined with the bf(--ignore-existing) option, no files will be updated

dit(bf(--ignore-existing)) This tells rsync to skip updating files that
already exist on the destination. See also bf(--ignore-non-existing).
-dit(bf(--ignore-non-existing)) This tells rsync to skip updating files that

-bf(--ignore-existing) option, no files will be updated (which can be useful
-if all you want to do is to delete missing files). Note that in older
-versions of rsync, this option was named bf(--existing), so this older
-name is still accepted as an alias.

dit(bf(--remove-sent-files)) This tells rsync to remove from the sending
side the files and/or symlinks that are newly created or whose content is
updated on the receiving side. Directories and devices are not removed,
Prior to rsync 2.6.7, this option would have no effect unless bf(--recursive)

+(bf(-d)) is in effect, but only for directories whose contents are being copied.
This option can be dangerous if used incorrectly! It is a very good idea
to run first using the bf(--dry-run) option (bf(-n)) to see what files would be
suffixed with a string to indicate a size multiplier, and
may be a fractional value (e.g. "bf(--max-size=1.5m)").
-The suffixes are as follows: "K" (or "k") is a kilobyte (1024),
-"M" (or "m") is a megabyte (1024*1024), and "G" (or "g") is a
-gigabyte (1024*1024*1024).
-If you want the multiplier to be 1000 instead of 1024, suffix the K, G, or
-M with a "T" (or "t") to indicate that a power of 10 is desired.
+The suffixes are as follows: "K" (or "KiB") is a kibibyte (1024),
+"M" (or "MiB") is a mebibyte (1024*1024), and "G" (or "GiB") is a
+gibibyte (1024*1024*1024).
+If you want the multiplier to be 1000 instead of 1024, use "KB",
+"MB", or "GB". (Note: lower-case is also accepted for all values.)
Finally, if the suffix ends in either "+1" or "-1", the value will
be offset by one byte in the indicated direction.

+presented to rsync as a single argument. You must use spaces (not tabs
+or other whitespace) to separate the command and args from each other,
+and you can use single- and/or double-quotes to preserve spaces in an
+argument (but not backslashes). Note that doubling a single-quote
+inside a single-quoted string gives you a single-quote; likewise for
+double-quotes (though you need to pay attention to which quotes your

+quote(
+tt( -e 'ssh -p 2234')nl()
+tt( -e 'ssh -o "ProxyCommand nohup ssh firewall nc -w1 %h %p"')nl()

(Note that ssh users can alternately customize site-specific connect
options in their .ssh/config file.)
dit(bf(-i, --itemize-changes)) Requests a simple itemized list of the
changes that are being made to each file, including attribute changes.
This is exactly the same as specifying bf(--log-format='%i %n%L').

then it is matched against the full pathname, including any leading
directories. If the pattern doesn't contain a / or a "**", then it is
matched only against the final component of the filename.
(Remember that the algorithm is applied recursively so "full filename"
can actually be any portion of a path from the starting directory on
down.)
