- - Added the --append option that makes rsync append data onto files that
- are longer on the source than the destination (this includes new files).
-
- - Added the --min-size=SIZE option to exclude small files from the
- transfer.
-
- - Added the --compress-level option to allow you to set how aggressive
- rsync's compression should be (this option implies --compress).
-
- - Enhanced the parsing of the SIZE value for --min-size and --max-size to
- allow easy entry of multiples of 1000 (instead of just multiples of 1024)
- and off-by-one values too (e.g. --max-size=8mb-1).
-
- - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
- high-bit characters that it thinks are unreadable in the current locale.
-
- - The new option --human-readable (-h) changes the output of --progress,
- --stats, and the end-of-run summary to be easier to read. If repeated,
- the units become powers of 1024 instead of powers of 1000. (The old
- meaning of -h, as a shorthand for --help, still works as long as you
- just use it on its own, as in "rsync -h".)
-
- - If lutimes() and/or lchmod() are around, use them to allow the
- preservation of attributes on symlinks.
-
- - The --link-dest option now affects symlinks and devices (when possible).
-
- - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and
- "post-xfer exec". These allow a command to be specified on a per-module
- basis that will be run before and/or after a daemon-mode transfer. (See
- the man page for a list of the environment variables that are set with
- information about the transfer.)
-
- - When using the --relative option, you can now insert a dot dir in
- the source path to indicate where the replication of the source dirs
- should start. For example, if you specify a source path of
- rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
- replicate the "baz/dir" part of the source path (note: a trailing
- dot dir is unaffected unless it also has a trailing slash).
-
- - Added some new --no-FOO options that make it easier to override unwanted
- implied or default options. For example, "-a --no-o" (aka "--archive
- --no-owner") can be used to turn off the preservation of file ownership
- that is implied by -a.
+ - A new incremental-recursion algorithm is now used when rsync is talking
+ to another 3.0.0 version. This starts the transfer going more quickly
+ (before all the files have been found), and requires much less memory.
+ See the --recursive option in the manpage for some restrictions.
+
+ - The default --delete algorithm is now --delete-during when talking to a
+ 3.x rsync. This is a faster scan than using --delete-before (which is
+ the default when talking to older rsync versions), and is compatible with
+ the new incremental recursion mode.
+
+ - Added the --delete-delay option, which is a more efficient way to delete
+ files at the end of the transfer without needing a separate delete pass.
+
+ - Added the --acls (-A) option to preserve Access Control Lists. This is
+ an improved version of the prior patch that was available. (If you need
+ to have backward compatibility with old, patched versions, the new
+ acls.diff patch that will add that.)
+
+ - Added the --xattrs (-X) option to preserver extended attributes. This is
+ an improved version of the prior patch that was available. (If you need
+ to have backward compatibility with old, patched versions, the new
+ xattrs.diff patch that will add that.)
+
+ - Added the --fake-super option that allows a non-super user to preserve
+ all attributes of a file by using a special extended-attribute idiom.
+ There is also an analogous "fake super" option for an rsync daemon.
+
+ - Added the --iconv option, which allows rsync to convert filenames from
+ one character-set to another during the transfer. The default is to make
+ this feature available as long as your system has iconv_open(). If
+ compilation fails, specify --disable-iconv to configure and rebuild. If
+ you want rsync to perform character-set conversions by default, you can
+ specify --enable-iconv=CONVERT_STRING with the default value for the
+ --iconv option that you wish to use. For example, --enable-iconv=. is a
+ good choice. See the rsync man page for an explanation of the --iconv
+ option's settings.
+
+ - Added the --skip-compress=LIST option to override of the default list of
+ file suffixes that will not be compressed when using --compress.
+
+ - The --max-delete option now outputs a warning if it skipped any file
+ deletions, including a count of how many deletions were skipped. (Older
+ versions just silently stopped deleting things.)
+
+ - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
+ about any files that it wants to delete without deleting anything. If
+ you're not sure what version the client is, you can use the less-obvious
+ --max-delete=-1, as old and new versions will both treat that as the
+ same request (though older versions don't warn).
+
+ - The --hard-link option now uses less memory on both the sending and
+ receiving side for all protocol versions. For protocol 30, the use of a
+ hashtable on the sending side allows us to more efficiently convey to the
+ receiver what files are linked together. This reduces the amount of data
+ sent over the socket by a considerable margin (rather than adding more
+ data), and limits the in-memory storage of the device+inode information
+ to just the sending side for the new protocol 30, or to the receiving
+ side when speaking an older protocol (note that older rsync versions kept
+ the device+inode information on both sides).
+
+ - A lot more --no-OPTION override options are now supported.
