rsync prints "skipping non-regular file" for what appears to be a regular directory
提问by Richard
I back up my files using rsync. Right after a sync, I ran it expecting to see nothing, but instead it looked like it was skipping directories. I've (obviously) changed names, but I believe I've still captured all the information I could. What's happening here?
我使用 rsync 备份我的文件。同步后，我运行它，希望看不到任何东西，但看起来它正在跳过目录。我（显然）更改了名称，但我相信我仍然可以捕获所有信息。这里发生了什么事？
$ ls -l /source/backup/myfiles
drwxr-xr-x 2 me me 4096 2010-10-03 14:00 foo
drwxr-xr-x 2 me me 4096 2011-08-03 23:49 bar
drwxr-xr-x 2 me me 4096 2011-08-18 18:58 baz
$ ls -l /destination/backup/myfiles
drwxr-xr-x 2 me me 4096 2010-10-03 14:00 foo
drwxr-xr-x 2 me me 4096 2011-08-03 23:49 bar
drwxr-xr-x 2 me me 4096 2011-08-18 18:58 baz
$ file /source/backup/myfiles/foo
/source/backup/myfiles/foo/: directory
Then I sync (expecting no changes):
然后我同步（预计没有变化）：
$ rsync -rtvp /source/backup /destination
sending incremental file list
backup/myfiles
skipping non-regular file "backup/myfiles/foo"
skipping non-regular file "backup/myfiles/bar"
And here's the weird part:
这是奇怪的部分：
$ echo 'hi' > /source/backup/myfiles/foo/test
$ rsync -rtvp /source/backup /destination
sending incremental file list
backup/myfiles
backup/myfiles/foo
backup/myfiles/foo/test
skipping non-regular file "backup/myfiles/foo"
skipping non-regular file "backup/myfiles/bar"
So it worked:
所以它起作用了：
$ ls -l /source/backup/myfiles/foo
-rw-r--r-- 1 me me 3126091 2010-06-15 22:22 IMGP1856.JPG
-rw-r--r-- 1 me me 3473038 2010-06-15 22:30 P1010615.JPG
-rw-r--r-- 1 me me 3 2011-08-24 13:53 test
$ ls -l /destination/backup/myfiles/foo
-rw-r--r-- 1 me me 3126091 2010-06-15 22:22 IMGP1856.JPG
-rw-r--r-- 1 me me 3473038 2010-06-15 22:30 P1010615.JPG
-rw-r--r-- 1 me me 3 2011-08-24 13:53 test
but still:
但仍然：
$ rsync -rtvp /source/backup /destination
sending incremental file list
backup/myfiles
skipping non-regular file "backup/myfiles/foo"
skipping non-regular file "backup/myfiles/bar"
Other notes:
其他注意事项：
My actual directories "foo" and "bar" do have spaces, but no other strange characters. Other directories have spaces and have no problem. I 'stat'-ed and saw no differences between the directories that don't rsync and the ones that do.
我的实际目录“foo”和“bar”确实有空格，但没有其他奇怪的字符。其他目录有空格，没有问题。我 'stat'-ed 并看到没有 rsync 的目录和有的目录之间没有区别。
If you need more information, just ask.

Are you absolutely sure that it's not a symbolic link directory?
您绝对确定它不是符号链接目录吗？
try a:
尝试一个：
file /source/backup/myfiles/foo
to make sure it's a directory
确保它是一个目录
Also, it could very well be a loopback mount try
此外，它很可能是一个环回挂载尝试
mount
and make sure that /source/backup/myfiles/foo is not listed.
并确保 /source/backup/myfiles/foo 未列出。

Are you absolutely sure those individual filesare not symbolic links?
您确定这些单个文件不是符号链接吗？
Rsync has a few useful flags such as -lwhich will "copy symlinks as symlinks". Adding -lto your command:
Rsync 有一些有用的标志，例如-l“将符号链接复制为符号链接”。添加-l到您的命令中：
rsync -rtvpl /source/backup /destination
I believe symlinks are skipped by default because they can be a security risk. Check the man page or --help for more info on this:
我相信默认情况下会跳过符号链接，因为它们可能存在安全风险。查看手册页或 --help 以获取更多信息：
rsync --help | grep link
To verify these are symbolic links or pro-actively to find symbolic links you can use fileor find:
要验证这些是符号链接或主动查找符号链接，您可以使用file或find：
$ file /path/to/file
/path/to/file: symbolic link to `/path/file`
$ find /path -type l
/path/to/file

You can try the following, it will work
您可以尝试以下操作，它会起作用
rsync -rtvp /source/backup /destination
回答by mSatyam
You should try the below command, most probably it will work for you:
您应该尝试以下命令，它很可能对您有用：
rsync -ravz /source/backup /destination

I personally always use this syntax in my script and works a treat to backup the intire system (skipping sys/* & proc/* nfs4/*)
我个人总是在我的脚本中使用这种语法，并尝试备份整个系统（跳过 sys/* & proc/* nfs4/*）
sudo rsync --delete --stats --exclude-from $EXCLUDE -rlptgoDv / $TARGET/ | tee -a $LOG
Here is my script run by root's cron daily:
这是我每天由 root 的 cron 运行的脚本：
#!/bin/bash
#
NFS="/nfs4"
HOSTNAME=`hostname`
TIMESTAMP=`date "+%Y%m%d_%H%M%S"`
EXCLUDE="/home/gcclinux/Backups/root-rsync.excludes"
TARGET="${NFS}/${HOSTNAME}/SYS"
LOGDIR="${NFS}/${HOSTNAME}/SYS-LOG"
CMD=`/usr/bin/stat -f -L -c %T ${NFS}`
## CHECK IF NFS IS MOUNTED...
if [[ ! $CMD == "nfs" ]];then
echo "NFS NOT MOUNTED"
exit 1
fi
## CHECK IF LOG DIRECTORY EXIST
if [ ! -d "$LOGDIR" ]; then
/bin/mkdir -p $LOGDIR
fi
## CREATE LOG HEADER
LOG=$LOGDIR/"rsync_result."$TIMESTAMP".txt"
echo "-------------------------------------------------------" | tee -a $LOG
echo `date` | tee -a $LOG
echo "" | tee -a $LOG
## START RUNNING BACKUP
/usr/bin/rsync --delete --stats --exclude-from $EXCLUDE -rlptgoDv / $TARGET/ | tee -a $LOG
