I’ve been a (mostly) happy customer of insync for a few years.
Nowadays, I can’t say how disappointed I am with it. I’m nowadays scared to have insync running, because I fear it will randomly start re-uploading files that never changed, stop synchronizing without any warning (just had one of these, I’m estimating it was blocked for a month or two). That’s the stuff I see. I always wonder if it would also start deleting some files soon ? Now that google empties trashes every 30 days, that would mean loss of data.
I know two-way sync is hard. But I also know that insync was working mostly seamlessly.
And when I asked for support, I was asked to “send us your logs”. You know, a massive database that essentially lists all files I have in my (professional) drive. As confidential information goes, you should have realized this is really bad.
So, now, I just uninstalled insync. I’m back to plain old browser. At least, I know how bad it works.
