Hi Andrea,
Thanks for your reply! I apologize the linked article covers all remote backup methods that are associated with Total Upkeep, this includes Amazon S3 and Google Drive along with SFTP/FTP connections. The very first section details the steps for setting up an FTP/SFTP connection:
Configure Your backup on FTP / SFTP Storage
1.) In the Dashboard, Navigate to Total Upkeep → Settings
2.) Under the Backup Storage Section, Select Configure FTP
3.) Provide your connection credentials
4.) Click Save Changes
Thanks Andrea! Please let us know if we can answer anything else for you!
