最近豆子公司在转移文件服务器,大概有80T的文件需要传送到云端。豆子直接使用了robocopy进行拷贝。因为历史原因,有些文件夹的权限设置比较奇葩,导致豆子的账户也没有权限去访问,这样的结果就是Robocopy里面可能会有几十百甚至上千个文件夹因为权限问题而无法拷贝。
robocopy 命令例子

robocopy c:\ source d:\destination /E /w :30 /r :3 /log +: "c:\temp\log.txt" /xf .*
|
那么如果解决这个问题呢?豆子的思路是获取robocopy的日志文件,通过正则提取其中失败的路径,然后通过脚本重新夺取管理员权限,然后重新赋予NTFS的权限。
比如说,下面的robocopy 日志,报错信息如下所示

因为最近在复习Python,顺手又用Python写了一个同样的功能,效果是一样的

fp = open ( 'c:/temp/tracktransfer.txt' )
fp2 = open ( 'c:/temp/list.txt' , 'w' )
contents = fp.read()
pat = r '(\\\\syd02.*\n)Access is denied'
ret = re.findall(pat,contents)
ret = set (ret)
for item in ret:
print (item)
fp2.write(item)
print ( "total number is %d" % len (ret))
fp.close() fp2.close() |
-----------------------
然后接下来是重头戏,如何重新夺取权限和赋值?
PowerShell自带的Get-ACL和Set-ACL命令,以及DOS命令 takeown我都试过,老实说,不太好使,后来很幸运地在网上发现了一个第三方的模块 NTFSSecurity,里面的函数完全实现了我需要的功能。

下载之后,直接解压到对应的Powershell模块路径,然后重启PowerShell ISE就可以自动加载了。
下面是后半截代码,修改目标目录及其子目录文件的所有者和访问权限

get-item $i | Set-NTFSOwner -Account 'omnicom\group Australia it access'

$items = @()
$items = $null
$path = $null
#if need to setup all subfolders, we can use -recusrse in the following cmdlet.
$items = get-childitem $i -force
foreach ( $item in $items )

$path = $item .FullName
Write-Host ...Adding AdminGroup to $path -Fore Green

}

最后的效果是
这样子,如果RoboCopy出了什么权限方面的问题,我通过这个脚本就可以很容易的解决了,一次不行,修复之后再跑一次Robocopy很快就可以把丢失的文件拷贝回来了~
