- - 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.
-
- - Saved memory 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 --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.
