I can't find this option in the GUI. Also, can't find any reference to 
it in the wiki.

Only Google reported a message from 2012.

I see it also documented in pvesm manpage, took a while to find it as 
man storage.cfg as per Debian std doesn't work.

I think this should be more clearly reported, as can be a security 
problem. Maybe the default should be to saferemove.

Thanks
