- - 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.
-
- - Added the --chmod=MODE option that allows the destination permissions to
- be changed from the source permissions. E.g. --chmod=g+w,o-rwx
-
- - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
- a module to specify what permissions changes should be applied to all
- files copied to and from the daemon.
-
- - Allow the --temp-dir option to be specified when starting a daemon, which
- sets the default temporary directory for incoming files.
-
- - If --delete is combined with --dirs without --recursive, rsync will now
- delete in any directory whose content is being synchronized.
-
- - If --backup is combined with --delete without --backup-dir (and without
- --delete-excluded), we add a "protect" filter-rule to ensure that files
- with the backup suffix are not deleted.
-
- - The file-count stats that are output by --progress were improved to
- better indicate what the numbers mean. For instance, the output:
- "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
- to be transferred, and we still need to check 8383 more files out of
- a total of 9999.
-
- - The include/exclude code now allows a dir/*** directive (with 3 trailing
- stars) to match both the dir itself as well as all the content below the
- dir (dir/** would not match the dir).
-
- - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
- discard empty chains of directories from the file-list. This makes it
- easier to selectively copy files from a source hierarchy and end up with
- just the directories needed to hold the resulting files.
-
- - If the --itemize-changes (-i) option is repeated, rsync now includes
- unchanged files in the itemized output (similar to -vv, but without all
- the other verbose messages that can get in the way). Of course, the
- client must be version 2.6.7 for this to work, but the remote rsync only
- needs to be 2.6.7 if you're pushing files.
-
- - Added the --specials option to tell rsync to copy non-device special
- files (which rsync now attempts even as a normal user). The --devices
- option now requests the copying of just devices (character and block).
- The -D option still requests both (e.g. --devices and --specials), -a
- still implies -D, and non-root users still get a silent downgrade that
- omits device copying.
-
- - Added the --super option to make the receiver always attempt super-user
- activities. This is useful for systems that allow things such as devices
- to be created or ownership to be set without being UID 0, and is also
- useful for someone who wants to ensure that errors will be output if the
- receiving rsync isn't being run as root.
-
- - Added the --sockopts option for those few who want to customize the TCP
- options used to contact a daemon rsync.
-
- - Added a way for the --temp-dir option to be combined with a partial-dir
- setting that lets rsync avoid non-atomic updates (for those times when
- --temp-dir is not being used because space is tight).
-
- - A new support script, files-to-excludes, will transform a list of files
- into a set of include/exclude directives that will copy those files.
-
- - A new option, --executability (-E) can be used to preserve just the
- execute bit on files, for those times when using the --perms option is
- not desired.
-
- - The daemon now logs each connection and also each module-list request
- that it receives.
-
- - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
- (permission bits, e.g. "rwxr-xrwt").
-
- - The --dry-run option no longer forces the enabling of --verbose.
-
- - The --remove-sent-files option now does a better job of incrementally
- removing the sent files on the sending side (older versions tended to
- clump up all the removals at the end).
-
- - A daemon now supersedes its minimal SIGCHLD handler with the standard
- PID-remembering version after forking. This ensures that the generator
- can get the child-exit status from the receiver.
-
- - Use of the --bwlimit option no longer interferes with the remote rsync
- sending error messages about invalid/refused options.
-
- - Rsync no longer returns a usage error when used with one local source arg
- and no destination: this now implies the --list-only option, just like
- the comparable situation with a remote source arg.
-
- - Added the --copy-dirlinks option, a more limited version of --copy-links.
-
- - Various documentation improvements, including: a better synopsis, some
- improved examples, a better discussion of the presence and absence of
- --perms (including how it interacts with the new --executability and
- --chmod options), an extended discussion of --temp-dir, an improved
- discussion of --partial-dir, a better description of rsync's pattern
- matching characters, an improved --no-implied-dirs section, and the
- documenting of what the --stats option outputs.
-
- - Various new and updated diffs in the patches dir, including: acls.diff,
- xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
+ - A new incremental-recursion algorithm is now used when rsync is talking
+ to another 3.x 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.
+
+ - Lowered memory use in the non-incremental-recursion algorithm for typical
+ option values (usually saving from 21-29 bytes per file).
+
+ - 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.
+
+ - Rsync now allows multiple remote-source args to be specified rather than
+ having to rely on a special space-splitting side-effect of the remote-
+ shell. Additional remote args must specify the same host or have an
+ empty hostname, as seen here: :file1 ::module/file2. This means that
+ local use of brace expansion now works: rsync -av host:path/{f1,f2} .
+
+ - Added the --protect-args (-s) option, that tells rsync to send most of
+ the command-line args at the start of the transfer rather than as args
+ to the remote-shell command. This protects them from space-splitting,
+ and only interprets basic wildcard special shell characters (*?[).
+
+ - 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, and it even
+ supports OS X ACLs. (If you need to have backward compatibility with
+ old, patched versions of rsync, apply the acls.diff file from the patches
+ dir.)
+
+ - 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 of rsync, apply
+ the xattrs.diff file from the patches dir.)
+
+ - 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 then
+ 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 manpage for an
+ explanation of the --iconv option's settings.
+
+ - Added the --skip-compress=LIST option to override the default list of
+ file suffixes that will not be compressed when using --compress.
+
+ - The daemon's default for "dont compress" was extended to include:
+ *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
+ The matching routine was also optimized to run more quickly.
+
+ - 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 extraneous files without deleting anything. If you're not sure
+ what version the client is, you can use the less-obvious --max-delete=-1,
+ as both old and new versions will 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).
+
+ - The filter rules now support a perishable ("p") modifier that marks rules
+ that should not have an effect in a directory that is being deleted. e.g.
+ -f '-p .svn/' would only affect "live" .svn directories.
+
+ - If we get an error setting the time on a symlink, we don't complain about
+ it anymore (since some operating systems don't support that, and it's not
+ that important).
+
+ - Protocol 30 now uses MD5 checksums instead of MD4.
+
+ - Changed the --append option to not checksum the existing data in the
+ destination file, which speeds up file appending.
+
+ - Added the --append-verify option, which works like the older --append
+ option (verifying the existing data in the destination file). For
+ compatibility with older rsync versions, any use of --append that is
+ talking protocol 29 or older will revert to the --append-verify method.
+
+ - Documented and extended the support for the RSYNC_CONNECT_PROG variable
+ that can be used to enhance the client side of a daemon connection.
+
+ - Improved the dashes and double-quotes in the nroff manpage output.
+
+ - We now support a lot more --no-OPTION override options.
