# Duplicati for Windows
Duplicati is an open-source backup software for Windows, macOS, and Linux. Glesys Archive storage can be used as the backup target.
***
Together with Glesys Archive Storage, Duplicati is an excellent tool for handling your backups. Installation is straightforward, and you’ll be up and running quickly.
To install Duplicati on Windows, download the installer from [Duplicati's website](http://www.duplicati.com/), go through the installation steps, and choose “Launch Duplicati.”
## Initial configuration
If Duplicati isn't yet started, you'll find it in the Start menu or on the desktop. When you open Duplicati, a web browser will start with Duplicati's web interface. The graphical user interface of Duplicati is web-based.
The first time Duplicati is launched, you are asked to create a new passphrase. It's advised to do so, so that you can connect to it from other places in the future.
## Create a backup task
You are now presented with the main window. It's time to create our first backup task.
Click the **Add** button in the *Backups* field:
Then, select **Add new backup:**
In the next step, choose a name for the backup, select an encryption method, and choose a passphrase to protect the backup:
Next, we specify the backup destination. This is our Archive Storage. Select **FTP**.
For **Server**, enter the URL displayed when you created the Archive Storage. **Username** is the name of the Archive Storage you created.
If you don't enter a **Path on server**, the files will be stored in the root folder. You'll be asked if this is what you want before proceeding.
Once you have filled in the values, click **Add advanced option**.
In the **Add advanced option** drop-down menu, select **ftp-ssl-protocols**.
Then, in the *Advanced options* field, remove **None** and add **Ssl3**. Then, click **Continue**.
You then need to select what you want to back up. Either choose from the suggested folders or type a path in the field. In this example, we have selected the Pictures folder.
Then, select a suitable schedule for the backup. The backup will then run automatically.
In the final step, you can tweak the volume size. A volume in this context refers to how large each chunk will be, as backups are split into multiple files.
You can also set up the backup retention in this step. For example, if you want to keep all backups or delete backups after a certain number of days or weeks.
Once you are satisfied, click **Submit**.
## Restore files from a backup
To restore files from a backup, click the three dots next to your backup job and select **Restore**.
In the next step, you get to choose which files you want to restore. Here you can select either individual files or the entire top directory. In this example, we have only selected two files:
In the final step, you can choose where you want your files to be restored. Either to the original location or a new location. In this example, we choose to restore the files to the Downloads folder:
Your files will now be restored to the Downloads folder.
