Backing Up a NAS Device

  • This article is for Windows only

The Billing Owner and Administrators on Carbonite Safe Backup Pro accounts can select data on Network Attached Storage (NAS) devices using a Windows computer. Before you get started, make sure you are on the correct Carbonite plan and the NAS device has been mapped to a drive letter, at which point the mapped device can be selected for backup by Carbonite like an internal or external drive.

To select data on a NAS, right-click the drive or its contents in File Explorer and select Carbonite; Back this up.

If you are unable to select a NAS device for backup while running Windows 10, please log off and log back onto your computer. If you are still experiencing difficulty selecting your NAS device, please reboot your computer.

When data on a NAS device is selected, Carbonite will associate the NAS with the Windows user signed in when the data was selected and the network path the device was mapped to, both of which become integral to the backup process.

NAS Requirements

The following table overviews the Carbonite Safe Backup Pro plans which support NAS device backup. Please note that the Carbonite Safe Backup Pro Core plan does not support Windows Server systems.

Warning: Backing up shared folders hosted on a different computer is not supported. Instead, install Carbonite directly to the computer hosting the data and select the data using its local path.

If Carbonite encounters an issue backing up selected files on a NAS device, you will see a warning notification indicating the name of the user that selected the files as well as the drive letter and network path. Please refer to the following example notification and the information below for details.

Windows User Requirements

Only one user per computer can select a NAS device for backup. If you log in to the computer backing up the NAS with a different Windows user, the backup of the NAS will not continue until you have logged back in with the original user. If needed, you can change which user is managing the NAS backup to a user better suited to manage it by reselecting the NAS device for backup while logged in under the new user.

Note: While logged in with a user who is not managing the NAS device’s backup, Carbonite will consider the NAS missing and its backed up data will be subject to removal after 60 days.

We recommend selecting the data for backup from a single computer that is always on and connected to both your local network and the internet. Similarly, we recommend selecting the data under a dedicated Windows user, one that is always logged in. Backing up data from a NAS through multiple computers create additional copies that will each count toward your account quota.

Network Path Requirements

To select a NAS device, it must be mapped to a drive letter using either the NAS device’s IP address or Universal Naming Convention (UNC). The network path cannot be changed once the drive is selected for backup.

Note: If the NAS device’s network path changes or Carbonite cannot connect to it, the device’s data will be considered missing and its backed up data will be subject to removal after 60 days.

If, for any reason, you have changed the network path of a NAS device and cannot change it back, you can create a second mapping to the device using the original network path. If the original drive letter is no longer available, Carbonite will recognize the NAS device's new drive letter under the original network path and continue backing up as normal.

Please follow the instructions below to map a NAS device on your computer.

  1. Open File Explorer by right-clicking the Start button, then clicking File Explorer.
  2. In the Navigation pane on the left, locate and right-click This PC, then select Map network drive... to open the Map Network Drive wizard.
  3. For the Drive drop-down, select a drive letter.
  4. In the Folder field, type the IP address or UNC path for the NAS device following format: \\[NAS Device name or IP Address]\[Share Name]. You can also click Browse to find the NAS device.
  5. Select the Reconnect at logon check box.
  6. Click Finish to connect, or map, the NAS device.

If you receive an error message about Network Discovery being turned off when attempting to map a NAS device, this setting will need to be turned on through the Network and Sharing Center under Advanced Sharing Settings. If you experience any difficulty mapping the NAS device or are unsure how it might affect your network setup, please contact your system administrator or IT professional.

Additional Information

The rules for a Backup Policy applied to the computer backing up the NAS device apply to the files on the NAS as well. In most cases, this regards the file types not automatically included with the backup. Such files would need to be selected manually. You can use Carbonite’s status dots to determine the backup status of your files.
