Robocopy is a useful tool that can be leveraged to copy files and folders from one location to another (e.g. Over the network to another server) without losing file and folder ACLs (permissions / ownership data).

!!! warning "Run as Domain Admin"
|
|
When you run Robocopy, especially when transferring data across the network to another remote server, you need to be sure to run the command prompt under the session of a domain admin. Secondly, it needs to be "Ran-as-Administrator" to ensure the command is successful. This can be done by going to the start menu and typing "Command Prompt" > Right Clicking > "Run as Administrator" while logged in as a domain administrator.

|
|
|
An example of using Robocopy is below, with a full breakdown:
|
|
```
|
|
robocopy "E:\Share" "Z:\Share" /Z /B /R:5 /W:5 /MT:4 /COPYALL /E
|
|
```
|
|
- `robocopy` : The application itself
|
|
- `"source\folder" "destination\folder"` : Self-Explanatory
|
|
- `/Z` : Network Resume Mode - If the network connection (if using a network share or something) is interrupted, it will resume when the network comes back online `Useful if the network is unstable`
|
|
- `/B` : Backup Mode - This, in some unique circumstances, can be used to circumvent ACLs on folders and files, just forcing them to copy bypassing permissions
|
|
- `R:5` : Number of times to retry copying the same file
|
|
- `W:5` : The number of seconds to wait between retries
|
|
- `/MT:4` : *_Threaded_* copies that run on their own threads
|
|
- `/COPYALL` : Retain all file/folder permissions and ownership data
|
|
- `/E` : Copy every folder, including empty ones
|
|
|
|
!!! tip "Usage of Administrative Shares"
|
|
Whenever dealing with copying data from one server to another, try to leverage "Administrative Shares", sometimes referred to as "Default Shares". These exist in such a way that, if the server exists in a Windows-based domain, you can type something like `\\SERVER\C$` or `\\SERVER\E$` to access files and bypass most file access restrictions (Generally for reading data, writing works too, but not in all circumstances).
|
|
|
|
An adjusted example can be seen below to account for this usage. **This example assumes you are running robocopy from the source computer**.
|
|
```
|
|
robocopy "E:\Share" "\\DESTINATION-SERVER\E$\Share" /Z /B /R:5 /W:5 /MT:4 /COPYALL /E
|
|
``` |
