Some of the additional features of rsync are:
-itemize(
+itemization(
it() support for copying links, devices, owners, groups, and permissions
it() exclude and exclude-from options similar to GNU tar
it() a CVS exclude mode for ignoring the same files that CVS would ignore
"USING RSYNC-DAEMON FEATURES VIA A REMOTE-SHELL CONNECTION" section for
an exception to this latter rule).
-As a special case, if a remote source is specified without a destination,
-the remote files are listed in an output format similar to "ls -l".
+As a special case, if a single source arg is specified without a
+destination, the files are listed in an output format similar to "ls -l".
As expected, if neither the source or destination path specify a remote
host, the copy occurs locally (see also the bf(--list-only) option).
Using rsync in this way is the same as using it with a remote shell except
that:

+any way. See the bf(--out-format) option for more details.
dit(bf(-q, --quiet)) This option decreases the amount of information you
are given during the transfer, notably suppressing information messages
from the remote server. This flag is useful when invoking rsync from
cron.
+dit(bf(--no-motd)) This option affects the information that is output
+by the client at the start of a daemon transfer. This suppresses the
+message-of-the-day (MOTD) text, but it also affects the list of modules
+that the daemon sends in response to the "rsync host::" request (due to
+a limitation in the rsync protocol), so omit this option if you want to
+request the list of modules from the daemon.
+
dit(bf(-I, --ignore-times)) Normally rsync will skip any files that are
already the same size and have the same modification time-stamp.
-This option turns off this "quick check" behavior.
+This option turns off this "quick check" behavior, causing all files to
+be updated.
dit(bf(--size-only)) Normally rsync will not transfer any files that are
already the same size and have the same modification time-stamp. With the
times with a 2-second resolution), bf(--modify-window=1) is useful
(allowing times to differ by up to 1 second).
-dit(bf(-c, --checksum)) This forces the sender to checksum all files using
-a 128-bit MD4 checksum before transfer. The checksum is then
-explicitly checked on the receiver and any files of the same name
-which already exist and have the same checksum and size on the
-receiver are not transferred. This option can be quite slow.
+dit(bf(-c, --checksum)) This forces the sender to checksum em(every)
+regular file using a 128-bit MD4 checksum. It does this during the initial
+file-system scan as it builds the list of all available files. The receiver
+then checksums its version of each file (if it exists and it has the same
+size as its sender-side counterpart) in order to decide which files need to
+be updated: files with either a changed size or a changed checksum are
+selected for transfer. Since this whole-file checksumming of all files on
+both sides of the connection occurs in addition to the automatic checksum
+verifications that occur during a file's transfer, this option can be quite
+slow.
+
+Note that rsync always verifies that each em(transferred) file was correctly
+reconstructed on the receiving side by checking its whole-file checksum, but
+that automatic after-the-transfer verification has nothing to do with this
+option's before-the-transfer "Does this file need to be updated?" check.
dit(bf(-a, --archive)) This is equivalent to bf(-rlptgoD). It is a quick
way of saying you want recursion and want to preserve almost
dit(bf(-r, --recursive)) This tells rsync to copy directories
recursively. See also bf(--dirs) (bf(-d)).
+Beginning with rsync 3.0.0, the recursive algorithm used is now an
+incremental scan that uses much less memory than before and begins the
+transfer after the scanning of the first few directories have been
+completed. This incremental scan only affects our recursion algorithm, and
+does not change a non-recursive transfer (e.g. when using a fully-specified
+bf(--files-from) list). It is also only possible when both ends of the
+transfer are at least version 3.0.0.
+
+Some options require rsync to know the full file list, so these options
+disable the incremental recursion mode. These include: bf(--delete-before),
+bf(--delete-after), bf(--prune-empty-dirs), bf(--delay-updates), and bf(--hard-links).
+Because of this, the default delete mode when you specify bf(--delete) is now
+bf(--delete-during) when both ends of the connection are at least 3.0.0
+(use bf(--del) or bf(--delete-during) to request this improved deletion mode
+explicitly). See also the bf(--delete-delay) option that is a better choice
+than using bf(--delete-after).
+
dit(bf(-R, --relative)) Use relative paths. This means that the full path
names specified on the command line are sent to the server rather than
just the last parts of the filenames. This is particularly useful when
quote(tt( rsync -av /foo/bar/baz.c remote:/tmp/))
-... this would create a file called baz.c in /tmp/ on the remote
+... this would create a file named baz.c in /tmp/ on the remote
machine. If instead you used
quote(tt( rsync -avR /foo/bar/baz.c remote:/tmp/))
-then a file called /tmp/foo/bar/baz.c would be created on the remote
+then a file named /tmp/foo/bar/baz.c would be created on the remote
machine -- the full path name is preserved. To limit the amount of
path information that is sent, you have a couple options: (1) With
a modern rsync on the sending side (beginning with 2.6.7), you can
-insert a dot dir into the source path, like this:
+insert a dot and a slash into the source path, like this:
quote(tt( rsync -avR /foo/./bar/baz.c remote:/tmp/))
That would create /tmp/bar/baz.c on the remote machine. (Note that the
-dot dir must followed by a slash, so "/foo/." would not be abbreviated.)
+dot must be followed by a slash, so "/foo/." would not be abbreviated.)
(2) For older rsync versions, you would need to use a chdir to limit the
source path. For example, when pushing files:
tt( remote:bar/baz.c /tmp/)
)
-dit(bf(--no-implied-dirs)) When combined with the bf(--relative) option, the
-implied directories in each path are not explicitly duplicated as part
-of the transfer. This makes the transfer more optimal and also allows
-the two sides to have non-matching symlinks in the implied part of the
-path. For instance, if you transfer the file "/path/foo/file" with bf(-R),
-the default is for rsync to ensure that "/path" and "/path/foo" on the
-destination exactly match the directories/symlinks of the source. Using
-the bf(--no-implied-dirs) option would omit both of these implied dirs,
-which means that if "/path" was a real directory on one machine and a
-symlink of the other machine, rsync would not try to change this.
+dit(bf(--no-implied-dirs)) This option affects the default behavior of the
+bf(--relative) option. When it is specified, the attributes of the implied
+directories from the source names are not included in the transfer. This
+means that the corresponding path elements on the destination system are
+left unchanged if they exist, and any missing implied directories are
+created with default attributes. This even allows these implied path
+elements to have big differences, such as being a symlink to a directory on
+one side of the transfer, and a real directory on the other side.
+
+For instance, if a command-line arg or a files-from entry told rsync to
+transfer the file "path/foo/file", the directories "path" and "path/foo"
+are implied when bf(--relative) is used. If "path/foo" is a symlink to
+"bar" on the destination system, the receiving rsync would ordinarily
+delete "path/foo", recreate it as a directory, and receive the file into
+the new directory. With bf(--no-implied-dirs), the receiving rsync updates
+"path/foo/file" using the existing path elements, which means that the file
+ends up being created in "path/bar". Another way to accomplish this link
+preservation is to use the bf(--keep-dirlinks) option (which will also
+affect symlinks to directories in the rest of the transfer).
+
+In a similar but opposite scenario, if the transfer of "path/foo/file" is
+requested and "path/foo" is a symlink on the sending side, running without
+bf(--no-implied-dirs) would cause rsync to transform "path/foo" on the
+receiving side into an identical symlink, and then attempt to transfer
+"path/foo/file", which might fail if the duplicated symlink did not point
+to a directory on the receiving side. Another way to avoid this sending of
+a symlink as an implied directory is to use bf(--copy-unsafe-links), or
+bf(--copy-dirlinks) (both of which also affect symlinks in the rest of the
+transfer -- see their descriptions for full details).
dit(bf(-b, --backup)) With this option, preexisting destination files are
renamed as each file is transferred or deleted. You can control where 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
+(e.g. bf(-f "Pp *~")). This will prevent previously backed-up files from being
deleted. Note that if you are supplying your own filter rules, you may
need to manually insert your own exclude/protect rule somewhere higher up
in the list so that it has a high enough priority to be effective (e.g., if
rule would never be reached).
dit(bf(--backup-dir=DIR)) In combination with the bf(--backup) option, this
-tells rsync to store all backups in the specified directory. This is
-very useful for incremental backups. You can additionally
+tells rsync to store all backups in the specified directory on the receiving
+side. This can be used for incremental backups. You can additionally
specify a backup suffix using the bf(--suffix) option
(otherwise the files backed up in the specified directory
will keep their original filenames).
dit(bf(-l, --links)) When symlinks are encountered, recreate the
symlink on the destination.
-dit(bf(-L, --copy-links)) When symlinks are encountered, the file that
+dit(bf(-L, --copy-links)) When symlinks are encountered, the item that
they point to (the referent) is copied, rather than the symlink. In older
versions of rsync, this option also had the side-effect of telling the
receiving side to follow symlinks, such as symlinks to directories. In a
dit(bf(--copy-unsafe-links)) This tells rsync to copy the referent of
symbolic links that point outside the copied tree. Absolute symlinks
are also treated like ordinary files, and so are any symlinks in the
-source path itself when bf(--relative) is used.
+source path itself when bf(--relative) is used. This option has no
+additional effect if bf(--copy-links) was also specified.
dit(bf(--safe-links)) This tells rsync to ignore any symbolic links
which point outside the copied tree. All absolute symlinks are
also ignored. Using this option in conjunction with bf(--relative) may
give unexpected results.
-dit(bf(-H, --hard-links)) This tells rsync to recreate hard links on
-the remote system to be the same as the local system. Without this
-option hard links are treated like regular files.
+dit(bf(-k, --copy-dirlinks)) This option causes the sending side to treat
+a symlink to a directory as though it were a real directory. This is
+useful if you don't want symlinks to non-directories to be affected, as
+they would be using bf(--copy-links).
-Note that rsync can only detect hard links if both parts of the link
-are in the list of files being sent.
+Without this option, if the sending side has replaced a directory with a
+symlink to a directory, the receiving side will delete anything that is in
+the way of the new symlink, including a directory hierarchy (as long as
+bf(--force) or bf(--delete) is in effect).
-This option can be quite slow, so only use it if you need it.
+See also bf(--keep-dirlinks) for an analogous option for the receiving
+side.
-dit(bf(-K, --keep-dirlinks)) On the receiving side, if a symlink is
-pointing to a directory, it will be treated as matching a directory
-from the sender.
+dit(bf(-K, --keep-dirlinks)) This option causes the receiving side to treat
+a symlink to a directory as though it were a real directory, but only if it
+matches a real directory from the sender. Without this option, the
+receiver's symlink would be deleted and replaced with a real directory.
-dit(bf(-W, --whole-file)) With this option the incremental rsync algorithm
-is not used and the whole file is sent as-is instead. The transfer may be
-faster if this option is used when the bandwidth between the source and
-destination machines is higher than the bandwidth to disk (especially when the
-"disk" is actually a networked filesystem). This is the default when both
-the source and destination are specified as local paths.
+For example, suppose you transfer a directory "foo" that contains a file
+"file", but "foo" is a symlink to directory "bar" on the receiver. Without
+bf(--keep-dirlinks), the receiver deletes symlink "foo", recreates it as a
+directory, and receives the file into the new directory. With
+bf(--keep-dirlinks), the receiver keeps the symlink and "file" ends up in
+"bar".
+
+See also bf(--copy-dirlinks) for an analogous option for the sending side.
+
+dit(bf(-H, --hard-links)) This tells rsync to look for hard-linked files in
+the transfer and link together the corresponding files on the receiving
+side. Without this option, hard-linked files in the transfer are treated
+as though they were separate files.
+
+Note that rsync can only detect hard links if both parts of the link
+are in the list of files being sent.
dit(bf(-p, --perms)) This option causes the receiving rsync to set the
destination permissions to be the same as the source permissions. (See
When this option is em(off), permissions are set as follows:
-quote(itemize(
+quote(itemization(
it() Existing files (including updated files) retain their existing

directory inherits a setgid bit from its parent directory.

versions erroneously preserved the three special permission bits for

+dit(bf(-A, --acls)) This option causes rsync to update the destination
+ACLs to be the same as the source ACLs. This nonstandard option only
+works if the remote rsync also supports it. bf(--acls) implies bf(--perms).
+
+dit(bf(-X, --xattrs)) This option causes rsync to update the remote
+extended attributes to be the same as the local ones. This will work
+only if the remote machine's rsync supports this option also. This is
+a non-standard option.
+
dit(bf(--chmod)) This option tells rsync to apply one or more
comma-separated "chmod" strings to the permission of the files in the
transfer. The resulting value is treated as though it was the permissions

-data over the wire and data being matched locally), and the estimated time
-remaining in this transfer.
+In this example, the receiver has reconstructed 782448 bytes or 63% of the
+sender's file, which is being reconstructed at a rate of 110.64 kilobytes
+per second, and the transfer will finish in 4 seconds if the current rate
+is maintained until the end.
+
+These statistics can be misleading if the incremental transfer algorithm is
+in use. For example, if the sender's file consists of the basis file
+followed by additional data, the reported rate will probably drop
+dramatically when the receiver gets to the literal data, and the transfer
+will probably take much longer to finish than the receiver estimated as it
+was finishing the matched part of the file.
-After a file is complete, the data looks like this:
+When the file transfer finishes, rsync replaces the progress line with a
+summary line that looks like this:

+verb( 1238099 100% 146.38kB/s 0:00:08 (xfer#5, to-check=169/396))
-This tells you the final file size, that it's 100% complete, the final
-transfer rate for the file, the amount of elapsed time it took to transfer
-the file, and the addition of a total-transfer summary in parentheses.
-These additional numbers tell you how many files have been updated, and
-what percent of the total number of files has been scanned.
+In this example, the file was 1238099 bytes long in total, the average rate
+of transfer for the whole file was 146.38 kilobytes per second over the 8
+seconds that it took to complete, it was the 5th transfer of a regular file
+during the current rsync session, and there are 169 more files for the

+the 396 total files in the file-list.

+The options bf(--server) and bf(--sender) are used internally by rsync,
+and should never be typed by a user under normal circumstances. Some
+awareness of these options may be needed in certain scenarios, such as
+when setting up a login that can only run an rsync command. For instance,
+the support directory of the rsync distribution has an example script
+named rrsync (for restricted rsync) that can be used with a restricted
+ssh login.
