90% of my data losses are caused by rsync'ing from dir A to dir A (accidental incorrect copy and paste, or where dir B is a symlink to dir A). The source gets erased unintentionally.
It may seem dumb but when you get really long commands and really long file paths it will happen a 1-2 times a year when I'm doing it dozens/hundreds of times every week. *Is there an existing mechanism to protect against this?* rsync should logically never erase all copies of data. I know I can backup files (which I do for my smaller drives), or create wrapper scripts but I'm not asking about those. I don't think adopting --dry-run is practical being such a heavy user (and moreover, it's unlikely to warn what will happen). I'm not a C developer so I probably can't do this myself but if anyone's encouraging me to then I'd give it a shot.
