Rsync is perfect to incrementally backup a remote server on macOS or Linux:
rsync -a firstname.lastname@example.org:/srv/users/username/apps/sync-this "/Volumes/Server Backup/"
rsync The program we’re using
-a archive mode
user The user we’re using to connect to the server.
@126.96.36.199 The server we’re connecting to.
:/srv/users/username/apps/sync-this The folder you want to backup.
"/Volumes/Server Backup/" The - local - backup destination.
The reason I’m using the quotation mark for
"/Volumes/Server Backup/" is that there’s a space between Server and Backup.
