- - Added the --log-file=FILE and --log-file-format=FORMAT options. These
- can be used to tell any rsync to output what it is doing to a log file.
- They work with a client rsync, a non-daemon server rsync (see the man
- page for instructions), and also allows the overriding of rsyncd.conf
- settings when starting a daemon.
-
- - The --log-format option was renamed to be --out-format to avoid confusing
- it with affecting the log-file output. (The old option remains as an
- alias for the new to preserve backward compatibility.)
-
- - Made "log file" and "syslog facility" settable on a per-module basis in
- the daemon's config file.
-
- - Added the --remove-source-files option as a replacement for the (now
- deprecated) --remove-sent-files option. This new option removes all
- non-dirs from the source directories, even if the file was already
- up-to-date. This fixes a problem where interrupting an rsync that
- was using --remove-sent-files and restarting it could leave behind
- a file that the earlier rsync synchronized, but didn't get to remove.
- (The deprecated --remove-sent-files is still understood for now, and
- still behaves in the same way as before.)
-
- - Added a new environment variable to the pre-/post-xfer exec commands (in
- the daemon's config file): RSYNC_PID. This value will be the same in
- both the pre- and post-xfer commands, so it can be used if the pre-xfer
- command wants to cache some arg/request info for the post-xfer command.
+ - 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 an empty one
+ (e.g. empty: :file1 or ::module/file2). This means that local use of
+ brace expansion now works: rsync -av host:dir/{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,
+ ACL-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, and it even
+ supports OS X xattrs (which includes their resource fork data). If you
+ need to have backward compatibility with old, xattr-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.
+ It even supports the storing of foreign ACL data on your backup server.
+ 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.
+
+ - Rsync checks all the alternate-destination args for validity (e.g.
+ --link-dest). This lets the user know when they specified a directory
+ that does not exist.
+
+ - 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.
+
+ - Added the --contimeout=SECONDS option that lets the user specify a
+ connection timeout for rsync daemon access.
+
+ - 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.
