I am happy with "luckybackup"!https://luckybackup.sourceforge.net/
Yes, luckyBackup is clear, easy to set up and, importantly, based on rsync and not a properitary format. However, the last version is almost 5 years old and development has been frozen.Even though, thanks to rsync, I don't fear that luckyBackup will become unusable overnight, but this fact should be kept in mind.edlin
