Rsync 3.1.2 发布，此版本是个 bug 修复版本，包括了一个安全修复。 更新内容 安全修复 - Make sure that all transferred files use only path names from inside the transfer. BUG 修复 - Change the checksum seed order in the per-block checksums. This prevents someone from trying to create checksum blocks that match in sum but not content. - Fixed a with the per-dir filter files (using -FF) that could trigger an assert failure. - Only skip set_modtime() on a transferred file if the time is exactly right. - Don't create an empty backup dir for a transferred file that doesn't exist yet. - Fixed a bug where --link-dest and --xattrs could cause rsync to exit if a filename had a matching dir of the same name in the alt-dest area. - Allow more than 32 group IDs per user in the daemon's gid=LIST config. - Fix the logging of %b & %c via --log-file (daemon logging was already correct, as was --out-format='%b/%c'). - Fix erroneous acceptance of --info=5 & --debug=5 (an empty flag name is not valid). 改进： - Added "(DRY RUN)" info to the --debug=exit output line. - Use usleep() for our msleep() function if it is available. - Added a few extra long-option names to rrsync script, which will make BackupPC happier. - Made configure choose to use linux xattrs on netbsd (rather than not supporting xattrs). - Added -wo (write-only) option to rrsync support script. - Misc. manpage tweaks. 开发相关： - Fixed a bug with the Makefile's use of INSTALL_STRIP. - Improve a test in the suite that could get an erroneous timestamp error. - Tweaks for newer versions of git in the packaging tools. - Improved the m4 generation rules and some autoconf idioms. 源代码现已提供下载：rsync-3.1.2.tar.gz(signature)，rsync-patches-3.1.2.tar.gz(signature，:rsync-3.1.1-3.1.2.diffs.gz(signature)。 更多内容请看发行说明。 rsync是类unix系统下的数据镜像备份工具，从软件的命名上就可以看出来了——remote sync。它的特性如下： 1、可以镜像保存整个目录树和文件系统。 2、可以很容易做到保持原来文件的权限、时间、软硬链接等等。 3、无须特殊权限即可安装。 4、优化的流程，文件传输效率高。 5、可以使用rcp、ssh等方式来传输文件，当然也可以通过直接的socket连接。 6、支持匿名传输。 Linux系统下如何使用rsync进行数据同步 rsync 3.1.2 发布，文件同步工具下载地址
