Synology Presto Client

Synology Presto Client and Presto File Server are tools designed especially for rapid and secure file transfer between your personal computers and Synology NAS. With Synology Presto Client, you can connect to multiple servers to upload/download files at a high-speed over WAN according to your needs, and can easily monitor the file transfer status. In addition, installing the desktop tool Synology Presto Automator allows you to schedule transfer tasks using its graphical user interface and even run tasks using its command-line interface (CLI), thereby increasing work efficiency.

Note:

  • To install and manage Presto File Server on your Synology device, log in as admin (or a user belonging to the administrators group) and go to Package Center to install Presto File Server, and then click the Help button on the upper-right corner for more information.
  • An option for installing Synology Presto Automator appears after the Synology Presto Client installer is executed. However, administrative permission is required to install Synology Presto Automator.
  • To access Presto File Server, the firewalls for port 3360 (TCP/UDP) and port 3361 (TCP/UDP) must be opened.

To determine the file conflict policy:

Before you start to transfer files, you can do the following to configure the file conflict policy for different connected servers:

  1. Go to Site Manager and find the section entitled Action when file already exists.
  2. Select one of the following four options when the filename of a transferred file already exists in the destination: Overwrite, Overwrite if file size is different or source is newer, Skip, and Rename.
  3. Click Apply to save the changes.

Note:

  • Anonymous login history is recorded in Site Manager.
  • When configuring the upload and download rates, the value of the maximum rate (minimum rate) should always be higher (lower) than that of the minimum rate (maximum rate), unless the maximum or minimum rate is set as unlimited.
  • After the minimum rate is configured, the file transfer speed will at least be as high as the configured rate. However, the actual transfer speed also depends on the local network environment, the server-side bandwidth limit, and the concurrent connections connected to the server.
