Presto File Server

Presto File Server is designed for rapid and secure file transfers between multiple Synology NAS servers or between personal computers and Synology NAS. With its two desktop utilities, Synology Presto Client and Synology Presto Automator, you can transfer between personal computers and Synology NAS. Presto File Server can centralize and monitor the network flow, and can offer exportable logs in details. In addition, admins can configure the connection and transfer rules to meet the needs of different business IT regulations.

Before you start:

• At least one Presto File Server license is required to use this package. You can make in-app purchases or visit the Presto File Server license page for more information on license plans.
• Before you can transfer files between Synology NAS and your local computer, the client application preferably with the same version as that of the connected server must be installed on the client computer first.
  • Go to Synology Download Center to download and install Presto File Server, and install Synology Presto Client and Synology Presto Automator using the same installer. Please note that administrative permission is required to install Synology Presto Automator.
  • To disable Presto File Server, go to Package Center > Installed and click Stop in the Action drop down menu.
• Before you can transfer files between multiple servers, Presto File Server with preferably the same version must be installed on these servers and the license must be activated within these servers. Go to Synology Download Center to download and install Presto File Server or download it directly from Package Center in DSM.
• To access Presto File Server, the firewalls for port 3360 (TCP/UDP) and port 3361 (TCP/UDP) must be opened.

Note: Port 3360 (TCP/UDP) and port 3361 (TCP/UDP) are the two default ports of Presto. When port-forwarding is required on Presto, please inform the client users to enter the port (N) corresponding to port 3360, and make sure the subsequent port (N + 1) is also open so that it can be mapped to port 3361. For example, when port 1001 is mapped to port 3360 of the address of Presto File Server, client users should enter port 1001 with the external IP address; in addition, administrators should make sure that port 1002 (not port 1000) is open and mapped to port 3361.

To permit DSM users to access Presto File Server:

1. Go to Control Panel > Privileges and select Presto File Server. Click Edit.
2. Go to the User or Group tab to enable users and groups to access Presto File Server. Specify IP settings where needed.

Site Express

In the Site Express page, you can create tasks for transferring files between multiple servers via Presto File Server.

To add a server:

Before starting a new transfer task, please follow the below instructions to add a server in the Server List tab.

1. Go to the Server List tab.
2. Click Add Server to add a server which you would like to transfer files to or transfer files from.
3. Follow the wizard to complete the process.

To edit a server:

1. Select the server you would like to edit from the list. You can also find the specific servers by using filters or entering the keywords of address or server name in the search bar.
2. Click Edit, Delete, or Details to view the details of the server and its related tasks.

To create a task:

In the Task List tab, you can create new transfer tasks by the below instructions.

1. Click Create Task.
2. Enter the task name and select the local directory.
3. Choose a Transfer direction for this task and click Next. The transfer direction cannot be modified after this task is created.
• Distributing: This server will be the data source of the task, transferring data to other servers from the selected directory.
• Collecting: The selected directory will be the destination of the data collected from other servers.
4. Click Add Server to add the servers from the Server List to this task.
5. Select a folder for the server as the path and click Apply. You can also click Create Folder to create a new folder.
6. Drag and drop the servers as the below instructions to configure the transfer topology, and then click Apply. The data transferring order will be depending on this topology.
• Move a server above/below another: You can move a server above or below another. However, data will be simultaneously transferred to or collected from the servers at the same level.
• Move a server to the next level of another: If it is a distributing task, data will be transferred to the upper server from your local host first, and then transferred to the lower from the upper. If it is a collecting task, data will be transferred from the lower to the upper, and then to your local host.

Note:

• The server on the upper level can start transferring files to the server on the next level even when the upper has not received the files completely.
• The transferring speed has a high dependency on the network environment.
7. Configure the transfer schedule and click Apply to complete the creation of this task. You can trigger this task manually, according to a set schedule, or as a followed task to other tasks. Click Advanced Settings to configure Transfer Settings, File Filter, and File Priority.

Note:

• A followed task will not be triggered if its previous task is cancelled, deleted, or has failed.

To manage a task:

Select a task and click Edit, Delete, or Cancel.

• Edit: Edit the name, local directory, transfer topology, schedule, transfer settings, file filter, and file priority of the task.
• Delete: Delete the selected task.
• Cancel: Cancel the selected ongoing transfer task.

To view the detail of a task:

Click on a task, and a task summary listing all the related servers will be displayed below the task list. Hover the mouse over a server in the list and click to view the file path, size, and the status for each independent file.

Policy

Presto File Server centralizes policy management and regulates file transfer speed, encryption, and compression matters for the connected users. Different policies can be configured to meet the needs of different DSM users and groups.

The policies are listed in order of priority: policy with the highest priority is listed on the top of the list. When more than one policy is applied to a connected user, only the policy with the highest priority is valid. To adjust the order of a policy, please drag the policy up or down the list.

Default policy is applied to all users including anonymous login or undefined connections, and always appears at the bottom of the list. This policy can be edited but cannot be deleted.

To create a policy:

1. Click Create and fill in the required fields.
2. Go to the User Policy tab to name the policy and set connection conditions, including maximum and minimum transfer rates. You can also enforce transfer compression, transfer encryption, or allow users with previous client versions to remain connected to the server.
3. Go to the Applied User tab to select the local groups and/or users that this policy will apply to.

To edit a policy:

Select a policy and then click Edit.

To regulate the transfer speed:

You can define the exact maximum or minimum transfer rates at Edit > Transfer Rate. Select Lock from the Upload rate and Download rate drop-down menu to make sure connected users can transfer data according to the exact set rates. If the Upload rate and Download rate is set to Disable, the transfer rate will not be regulated by the server, but will still be affected by the transfer rate on the client-side and other Synology NAS.

Settings

In the Settings page, you can set the total bandwidth that can be shared by all the clients connected to the server during file uploads or downloads.

This tab allows you to configure the access permissions of the anonymous account users. Please consult the section To permit anonymous login for more details.
