SSH File Transfer Protocol (SFTP)

SFTP (short for SSH File Transfer Protocol) is a network protocol used to secure and send file transfers over secure shell (SSH). Unlike both FTP and FTPS, SFTP uses only one connection and encrypts both authentication information and data files being transferred.

Using SFTP to perform data migration tasks can offer you the following benefits:

  • SFTP is supported by a variety of common FTP applications (e.g., Filezilla) and is something your IT organization is likely already familiar with
  • SFTP uses only one port which is always secured (better usability with firewalls)

Customers can choose the SFTP client they are most familiar with as long as the client supports concurrent uploads and downloads. Commonly used clients include:

Note: S-FTP is not currently accessible to client domain admins and is not compatible with a client domain setup.

Requesting an SFTP connection to RelativityOne

To request an SFTP connection to RelativityOne, contact your Relativity data migration specialist. They will work with you to determine whether SFTP is a good option for your current data migration project.

Configuration and setup

Note: You need to set up a site-to-site VPN connection in order to use SFTP. Contact your Relativity data migration specialist for further assistance.

Network environment configuration

Port 22 must be opened on your user machines and/or firewalls to allow data transfer via an SFTP connection to RelativityOne.

SFTP client configuration

Within the SFTP client you use, you must modify the "concurrent transfers" settings in the tool preferences to allow concurrent uploads and downloads.

Note: To optimize performance, we recommend setting the limit to between 10 and 20 simultaneous transfers. However, it is important to understand your own network conditions and chosen S-FTP client to ensure that these higher simultaneous transfer settings for optimized throughput can be supported.
