Hi all, I'm looking for a way to back up a local Windows file server to an offsite SFTP server. Specifically, I am looking for the following features: - Not just mounting the offside server as a drive, because some viruses target network drives as well. - Backups only sync changes, and does not have to re-upload all the contents every backup time. - If I delete a file, I can still restore it after the next backup has ran. Thanks in advance for your suggestions!
