Thank you both @shinyplastic and @mcaton , I think everything here would be useful for every customer in full panic for loosing important data.
I want to say I love The Brain. Really. The Brain, Directory Opus and Visual Code Studio are my best friends (ok it sounds a little nerd, but you know what I mean) for decades now.
So my lesson learned the hard way: don't get in panic mode. Make zip copies of your files before try everything, just in case. Take your time, drink a sip of coffee then come here or ask for support and everything will get just fine. There are friends here.
But, just because it's Xmas (and at Xmas you must tell the truth) I really think we need an external backup tool. Something that could start togheter with the PC and silently make a consistent local backup every morning : I thought that a robocopy with /PURGE option would make the trick, but it's an handycraft solution, instead we need an industrial and confident tool.
Or someone think that The Brain is just a toy ? Or someone think that doesn't matter if every data will be loose just because a ramsonware decided to come here for a visit ? I (and I'm not alone) don't think so. There's really everything about my life here, and the cloud to me is not an option because of 60 gigabytes of space.
So, please, listen to your devoted customers and make an external incremental or differential local backup tool. Please.
Take my post as a pain in the back please :-)
And thank you for your help, support, and everyday job. Without you there wouldn't be The Brain
