Note that this option includes empty directories. Copies only the top N levels of the source directory tree. Uses Restart mode. If access is denied, this option uses Backup mode. Specifies the file properties to be copied. Fixes file security on all files, even skipped ones. Deletes destination files and directories that no longer exist in the source. Moves files, and deletes them from the source after they are copied.
Moves files and directories, and deletes them from the source after they are copied. Removes the specified attributes from copied files. Creates a directory tree and zero-length files only. Creates destination files by using 8. Turns off support for very long paths longer than characters. Monitors the source, and runs again when more than N changes are detected. Monitors source, and runs again in M minutes if changes are detected.
Specifies run times when new copies may be started. Checks run times on a per-file not per-pass basis. Specifies the inter-packet gap to free bandwidth on slow lines. Copies only files for which the Archive attribute is set. Copies only files for which the Archive attribute is set, and resets the Archive attribute. Includes only files for which any of the specified attributes are set. As mentioned above, there is a unique behavior related to security permissions and destination directories.
When using the mirror switch, you might find that the file permissions themselves are not changed, only destination folder permissions. This is by design as for performance, and for practical reasons, individual file permissions were not intended to be copied using the mirror command.
What does this look like in practice? The result of a mirror command will result in the following file and folder permission structure. As you can see, the only permissions that are carried over are the unique folder permissions. The unique file permissions will not be carried over. Of course, there are plenty of scenarios where you would like the permissions to be copied and kept in sync; those scenarios will be explored in further detail later on in the article.
These changes are primarily around copying file security permissions which are made easier in the Vista version of Robocopy. One of the simplest ways to take advantage of the mirror command is to simply mirror two directories on a single server. The verbose command is useful to see what Robocopy is doing and make sure the files that we want to copy are doing so. Depending on your needs, this might work just fine. File attributes are copied with the files, but the file security settings are not copied.
The next example you may want to see is how to properly copy over the files with the security intact? In this example, we have a directory with four files just like the first example.
In addition, we have modified the permissions on test2. Here we are also going to modify test3. After running the following command, we will see that the permissions related to the user are copied over. Since the files were the same but with different permissions, the correct permissions have been copied while the file data itself remains synced. Make sure to use Run as Administrator if you get access denied on copying over files. The setting of the permissions may require administrator rights to perform depending on your system security configuration.
Looking at the test2. If we check on test3. With all of these commands combined, you will have a robust solution for mirroring files over the network. To demonstrate this capability, we are mirroring files from a local directory to a remote file share using the fully qualified domain name FQDN of the remote server.
Utilizing restartable backup mode, multi-threading, share error handling, FAT file timing, and optimized retry and wait times you should have a robust but performant solution to sending files over the network. The reason for this is dependant on your environment. Without this command, the first incremental performed after a complete backup will contain some of the files that were copied in the complete backup, even though those files may not have changed. The script still functions safely and reliably without the attrib command.
However, it doesn't operate as efficiently as it does with it. Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. Thank you. This thread is locked.
