The most basic operation with robocopy is copying sources folders to the destination. In this example, we will copy the directory named mytest to the destination folder yourtest

robocopy最基本操作是将源文件夹复制到目标位置。 在此示例中，我们将名为mytest的目录复制到目标文件夹yourtest

We can also copy a file and folders to the remote system. We will provide a remote system hostname or IP address before the destination path. We can use \\BACKUPSERVER or \\10.5.2.30 to specify the remote system.

我们还可以将文件和文件夹复制到远程系统。 我们将在目标路径之前提供一个远程系统主机名或IP地址。 我们可以使用\\ BACKUPSERVER或\\ 10.5.2.30来指定远程系统。

In this example, we will copy the source directory named mytest to the remote system with IP address 192.168.122.46 under the path Users\ismail with the named yourtest .

在此示例中，我们将名为mytest的源目录复制到IP地址为192.168.122.46的远程系统上，并位于路径Users\ismail ，且名为yourtest 。

robocopy provides some filtering features while copying files. We can specify the filenames and extensions we want to copy. This will skip other file names and extensions. We will provide the file name or extension after the destination folder.

robocopy在复制文件时提供了一些过滤功能。 我们可以指定要复制的文件名和扩展名。 这将跳过其他文件名和扩展名。 我们将在目标文件夹之后提供文件名或扩展名。

In this example, we only want to copy *.txt extension files.

在此示例中，我们只想复制*.txt扩展名文件。

We can see from the output that only one file is copied but there was more than one file. Copied file name and byte count is also printed.

从输出中我们可以看到仅复制了一个文件，但是有多个文件。 复制的文件名和字节数也会打印出来。

By default, only first level directories are copied to the destination. If we need to copy all level and subdirectories folders we should enable /S.

默认情况下，仅将第一级目录复制到目标。 如果需要复制所有级别和子目录文件夹，则应启用/S

There is a very useful feature for robocopy where source files are not copied and just listed. This feature can be useful if we want to check existing files and folders. We can use /L option to print the list of files and directories.

robocopy有一个非常有用的功能，其中的源文件不会被复制，而是被列出。 如果我们要检查现有文件和文件夹，则此功能很有用。 我们可以使用/L选项来打印文件和目录的列表。

As we can see from the output that all files and folders are skipped and not copied.

从输出中可以看到，所有文件和文件夹都被跳过而不复制。

While robocopy is mainly used to copy files from remote to local or local to remove we can use /L and /S options in order to list remote files. We can merge two options list and recursive to list all level files and folders.

尽管robocopy主要用于将文件从远程复制到本地或本地删除，但我们可以使用/L和/S选项列出远程文件。 我们可以合并两个选项列表和递归列表所有级别的文件和文件夹。

While copying files we can specify the size of files we want to copy. In this example we will copy files those sizes are lower than 1K .  We will use the /MAX option for this.

复制文件时，我们可以指定要复制的文件大小。 在此示例中，我们将复制那些大小小于1K 。 我们将使用/MAX选项。

As we can see from the results some of the files are copied but some of them are not copied because of the size restriction.

从结果中我们可以看到，由于大小限制，某些文件被复制了，但有些文件没有被复制。

The reverse of the previous option is /MIN option . This will only copy files higher than the given size. In this example, we will copy files higher than 1K which is 1000 kilobytes.

上一个选项的相反是/MIN选项。 这只会复制大于给定大小的文件。 在此示例中，我们将复制大于1K(即1000 KB)的文件。

The default behavior of robocopy is copying files. Sometimes we may need to move files. This can be done with robocopy too. We will provide /MOV option in order to move files and folders.

robocopy的默认行为是复制文件。 有时我们可能需要移动文件。 这也可以用robocopy完成。 我们将提供/MOV选项以移动文件和文件夹。

While doing copy and move operations we can also need some logs, especially in bulk data operations. We can write a log about specified operations with /LOG option. We can also specify the log file name y adding at the end of /LOG option. In this example, we will write robocopy operation log to log file named backup.log . This will prevent regular output

在执行复制和移动操作时，我们还需要一些日志，尤其是在批量数据操作中。 我们可以使用/LOG选项编写有关指定操作的/LOG 。 我们还可以指定在/LOG选项末尾添加的日志文件名y。 在此示例中，我们将robocopy操作日志写入名为backup.log日志文件。 这将阻止常规输出

The log file can be listed with type command in MS-DOS command line like below.

可以在MS-DOS命令行中使用type命令列出日志文件，如下所示。

Files and folders may have different properties. These properties can be used for different purposes like the listing owner, audit information, timestamps, etc. We can copy these attributes too with the robocopy command. Here are the attributes we can specify for the copy. We will also use /copy: option by adding the property we want to copy.

文件和文件夹可能具有不同的属性。 这些属性可用于列表所有者，审核信息，时间戳等不同目的。我们也可以使用robocopy命令复制这些属性。 这是我们可以为副本指定的属性。 我们还将通过添加要复制的属性来使用/copy:选项。

D is used to copy data properties

D用于复制数据属性

A used for attributes

A用于属性

T for time stamps

T为时间戳

S is used for NTFS access control list simply ACL

S用于NTFS访问控制列表，仅用于ACL

O is used for the owner information

O用于所有者信息

U is used for Auditing information

U用于审核信息

In this example, we will copy time stamp attributes or properties with the following command.

在此示例中，我们将使用以下命令复制时间戳记属性或属性。

We can also copy files with all properties of attributes with the /copyall parameter like below. This is equal to the /copy:DATSOU.

我们还可以使用/copyall参数复制具有属性的所有属性的文件，如下所示。 这等于/copy:DATSOU 。

If we are trying to make an identical copy of the local files and directories to the remote we need to purge or remove remote files and directories that no longer exist in the source. We can use /purge option for this.

如果我们尝试将本地文件和目录复制到远程目录，则需要清除或删除源文件中不再存在的远程文件和目录。 我们可以使用/purge选项。
