linux - rsync 在本地备份期间丢失了一个文件夹

Question

当我使用以下脚本在本地备份文件夹时，省略了子文件夹“core”:

mkdir {gsp,dst} 
svn co http://10.0.2.59:8118/svn/gsp/Development-Area/3-SCL/Trunk/TaskServer_Gsp gsp
rsync -auC gsp/* dst/
diff -rq gsp dst

输出是:

Only in gsp/com.boco.gdpp.taskserver.core/src/com/boco/gdpp/taskserver: core
Only in gsp: .svn

rsync命令的返回值为0，表示没有错误。以下是文件夹“gsp”和“dst”的结构，“core”不是最深的子文件夹。为什么“core”不能复制到“dst”？

tree -d gsp

-C 选项导致 rsync 忽略匹配各种模式的文件和目录，其中包括 core。此名称通常用于进程故障转储文件。从手册页:

The exclude list is initialized to:

    RCS SCCS CVS CVS.adm RCSLOG cvslog.* tags TAGS .make.state .nse_depinfo *~ #* .#* ,*  _$*  *$  *.old  *.bak  *.BAK
    *.orig *.rej .del-* *.a *.olb *.o *.obj *.so *.exe *.Z *.elc *.ln core .svn/

你可以覆盖它:

--include=core
