文件同步工具,rsync 3.1.2 發布
Rsync 3.1.2 發布,此版本是個 bug 修復版本,包括了一個安全修復。
更新內容
安全修復 - Make sure that all transferred files use only path names from inside the transfer. BUG 修復 - 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). 改進: - 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. 開發相關: - 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.

rsync是類unix系統下的數據鏡像備份工具,從軟件的命名上就可以看出來了——remote sync。它的特性如下:
1、可以鏡像保存整個目錄樹和文件系統。
2、可以很容易做到保持原來文件的權限、時間、軟硬鏈接等等。
3、無須特殊權限即可安裝。
4、優化的流程,文件傳輸效率高。
5、可以使用rcp、ssh等方式來傳輸文件,當然也可以通過直接的socket連接。
6、支持匿名傳輸。
