How to create inSync Storage on a NAS Share on Windows?


The Druva inSync Server service runs under the Local System Account by default, which does not have sufficient rights to access a Network Attached Storage (NAS)-based share. Hence, creating storage over a NAS share generally fails.

This article explains how you can create a storage on a NAS folder on Windows installation.

Note: This article applies to versions prior to inSync 5.5. For queries/issues with inSync 5.5, contact Druva Technical Support.


  1. The machine running the inSync 4.x or greater server must be a part of a Windows domain.
  2. The folder intended for storage must be empty.
  3. The Database folder and Database log folder must be stored on the local volume. They cannot be in a network location /share.

Changing the log on account for the inSync service

To create a new storage on the NAS share, the log-on account for Druva inSync Server service must be changed to a Windows domain account with proper permissions.

 Before you begin

  1. On the domain controller, create a new user account. For example: 'insyncserver' that will be used to run the inSync service.
  2. Stop the Druva inSync Server service.
  3. Stop the Druva inSync Server Control Panel service.
  4. Change the security permissions on the C:\inSyncServer4 directory and allow full control to the ‘insyncserver’ user account. The same must be done for the top level directories of all existing stores.

Note: For inSync 5.4 onwards the location for inSyncServer4 directory is "C:\ProgramData\Druva"

Steps for inSync 4.x:

Changing the log on account for the service

To change the log-on account for inSync service to 'inSyncServer':

     1. Open Administrator Tools > Services > Druva inSync Service

     2. Right click to see Properties. Click the Log On tab.

     3. Change the log on account name to 'inSyncServer' and click OK.


     4. Start the Druva inSync Server Control Panel service.

     5. Start the Druva inSync Server service.

Steps for inSync 5.x:

Changing the log on account for the service

To change the log-on account for inSync service to 'insyncserver':

     1. Druva Admin Web Console > Manage > Settings > Network > inSync Server Credentials.

      2. Click on the Edit button.

      3. Deselect the option "Use Local System Account".

      4. Enter the Username as 'insyncserver' followed by entering the Password. Click on the Save button.

Creating storage on a NAS folder

To create a NAS folder as a new storage:

  1. Grant ''insyncserver Full Control privileges in Sharing and Security permissions on the NAS folder.
  2. Create the new storage with NAS folder as the path for data storage, with database stored on a local disk folder.
