1. Use /Z or /ZB option:
  
  /Z or /ZB: Uses restartable mode. If the connection is lost during the copy, it will resume from where it left off. This can be beneficial for large transfers over a network.
2. Increase the number of threads with /MT:
  
  /MT[:n]: Specifies the number of threads to use (1-128). Increasing the number of threads can improve copy performance. Experiment with different values to find the optimal setting for your network.
3. Use /IPG:
  
  /IPG:n: Inter-Packet Gap (ms), introduces a delay between packets to reduce the impact on the network. Experiment with different values.
4. Check Network Bandwidth and Latency:
  
  Ensure that the network between the server and the remote resource is not the bottleneck. You can use network monitoring tools to check bandwidth and latency.
5. Consider Compression:
  
  If your network supports it, you may consider compressing the data during the transfer. This can be achieved using third-party tools or by compressing the data before transferring it.
Try this example.
```
robocopy "C:\uploads\test1" "\\tsclient\E\test2" /e /r:0 /w:0 /COPY:DAT /DCOPY:DAT /mt:32 /z /ipg:20
```

I tried this powershell on server and add my disk to remote local resource -

robocopy "C:\uploads\test1" "\\tsclient\E\test2" /e /r:0 /w:0 /COPY:DAT /DCOPY:DAT /mt:16

It copied one by one and also takes lot of time approx 19 hours.

I have to copy 3 lakhs + images

Please suggest

It looks like you are trying to write a script that uses both Bash and PowerShell commands. However, the script you provided is a mix of Bash and PowerShell syntax, which might be causing the "command not found" error.

Here is the updated version.
```
# PowerShell script for backup

$sourcePath = "\\cloud server\shared\folder"
$destinationPath = "E:\backup"

# Use Robocopy within PowerShell
robocopy $sourcePath $destinationPath /E /Z /COPYALL /R:3 /W:2

Write-Host "Backup completed!"
```
I think we discuss this on a different thread.!
