Backup to OneDrive or Other Cloud Storage Using a Simpel Script

By: Nicklas Møller Jepsen

Getting Started

I have a Office 365 Home/Family subscription that I use to get access to the latest version of the Office pack, get 1 TB (yes, tera byte) of included OneDrive storage and best of all; included in the subscription, is the possibility to add up to 4 other members of my family. That means that my girlfriend can get 1 TB online storage, without paying a dime, and for me that means I don't have to worry about helping her backup all of her photos and other stuff.

Now this is NOT a commecial for Microsoft/OneDrive, but the product they are offering are just amazing! To backup your files to the cloud, as I will walk you through in this guide, you can use any of the existing cloud storage providers; Dropbox, OneDrive/SkyDrive, you name it.

As a developer I have a ton of files on my system that I would hate to loose. This includes all the source code for the countless amount of projects I have worked upon in my spare time. All of these files I like to be able to control where they are physically stored on my hard drive, for instance I like to have a folder in C:\Dev where I store all my development projects. Surely I have set up a local subversion server hosted on my NAS, but what if the house burns to the ground? Therefore I needed to set up a backup of the subversion files on the NAS to be copied to OneDrive. Here's how it's done!

  1. Create a BAT file
  2. Create a Scheduled Task

And that's it!


I'm going to use ROBOCOPY, simple because it's amazing and has some features that I need for things to work the way I intend. Below is the command that we're going to run, in all its flavor. I will explain each part of the command afterwards.

robocopy X:\.subversion C:\Users\Nicklas\SkyDrive\Backup\MYNAS\.subversion /e /mir /log:C:\Users\Nicklas\SkyDrive\Backup\subversion_backup_log_%date:~-4,4%%date:~-10,2%%date:~-7,2%_%time:~0,2%-%time:~3,2%-%time:~6,2%.txt

The syntax is as follows:

robocopy [source] [destination] params 

Source and destination should be obvious. The parameters explained: /e : Copies all subfolders /mir : Will only copy newer/added files. Making the backup kind of incremental. /log : The path to store the log file.

Speaking of the log file; I using the syntaxt above to get a timestamp to put in the file name of the log file - otherwise it will just get overridden each time the backup is running. Depending on your Windows locale, that syntaxt might be different.

Scheduled Task

Open the the Task Scheduler, goto Run and enter: Taskschd.msc

Choose Create Task. Give it a name and select the Triggers tab and then New. Select Daily and leave the rest as defaults. Select the Actions tab and then New. Enter the path to the BAT script created in the previous step (I have stored mine in my OneDrive backup folder for ease of access). Then the last thing: Go to Settings tab click the If the task fails, restart every to make sure that the backup will be performed.

And we're done!


This wil only copy/replace new and existing files, it will not delete files no longer in the source. A fix for this is to manually "resetting" the destination files by deleting them and running a full backup from scratch one in a while.
