Robocopy

[MatthewL]

I currently have a batch file like this but with a few more folders in

 

net use z: \\192.168.1.109\Software
Robocopy E:\_Software Z:\ /mir

 

What I want to do is preserve the dates on the original files rather than the time it has copied over, also I want it to create a log file for each folder i.e. E:\logfile\software.txt

 

I will then run this on a weekly basis and it will copy over any new files but will this replicate any changes if I delete folders?

 

Cheers

Its been a while since I used RoboCopy in ernest, but I think the below /COPY switch is the one you need for you to manage what to copy along with the data.

 

This should copy the Data and the Timestamps.

/COPY:DT

 

Robocopy /? has more information around this.

 

Outputting the log

For outputting the log, I use PowerShell with the "| Out-Host" and "Transcript" functions.

 

In short, you could do something like this in a PowerShell Script to Start a Transcript to a file (using today's date) and RoboCopy Outputting to host:

$a = Get-Date -format d.M.yyyy
$b = "g:\blah-" + $a + ".txt"


Start-Transcript -path $b -append
Robocopy E:\Blah G:\Blah /mir /copy:DT | Out-Host
Stop-Transcript

 

This would result in the log file (called G:\Blah-22.8.2014) looking like this:

The "| Out-Host" is important as without it, the Robocopy is not picked up by the Transcript.

 

Other ways

There are many other ways to do this I'm sure, but this is the way that I have my Home Backup's configured (backing up my Web and File Servers to another desktop, which is then ultimately backed up to SugarSync)

 

Attached

Here is the PowerShell script used above:blah.ps1

net use z: \\192.168.1.109\Software
Robocopy E:\_Software Z:\ /mir

Instead of mapped drives use UNC paths instead because if the Z: drive fails to be mapped, your robocopy job will fail too.

 

It's also worth specifying the retry and wait times since the default for these is 1 million (!!!) and 30 respectively.

 

The following should do what you want.

 

@echo off

:: Get date/time in YYYY-MM-DD_HH.MM format
for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE 2^>NUL`) do if '.%%i.'=='.LocalDateTime.' set dt=%%j
set dt=%dt:~0,4%-%dt:~4,2%-%dt:~6,2%_%dt:~8,2%.%dt:~10,2%

:: Start backup
robocopy \\[color="#FF0000"]Source[/color]\e$\_Software \\192.168.1.109\Software /MIR /NP /DCOPY:DAT /SEC /TEE /R:5 /W:3 /V /LOG+:"\\[color="#FF0000"]Source[/color]\e$\LogFiles\Software_%dt%.log"

 

I will then run this on a weekly basis and it will copy over any new files but will this replicate any changes if I delete folders?

With /MIR, any files or folders that are added/deleted in the source will also be added/deleted in the destination.
