Who of you are using the backup engine? I’m tempted to remove the backup engine completely at this moment. The backup engine will not work for people with more then one inverter anyway.
Besides that, doing a full backup of all the inverter logfiles to FTP seems a bit of a security hole for most people. Most people do not have a private, dedicated, FTP server for themselves. In this case do you want your inverterfiles to reside on a FTP server?
Making a backup of the inverterfiles seems to be a task being done outside of jSunnyreports.
What do you think?
