Box has problems. I gratefully use it every day for backups. But whenever I attempt to actually SYNC with it to another of my Macs, the result is nothing less than UTTER DISASTER! I've decided to write this up here as the utter disaster is entirely repeatable and I know of no way to stop it. Plus, Box is entirely oriented toward Windows users, NOT MAC USERS. This is expressed specifically in the inability to use anything but DOS approved characters in names. That means a lot of Mac file names are NO GO. That's annoying.
Therefore, for Mac users and for those who want a real syncing program, look elsewhere! Box is NOT what you want.
The syncing problem:
I maintain a huge collection of files as research. Those that I want access to immediately are kept directly on my main Mac, a MacBook Pro. I also maintain a Mac Mini server. I want my research files there as well, of course. If I use Box Sync to sync between those two Macs via my Box backup, you'd think that would be dirt simple. But instead, UTTER DISASTER results. Of hundreds of folders in my research files collection, ALL but 10 of those folders were plain old DELETED! GONE! How is that even possible? And I've verified this three times. I've had to use my local backup to restore all my files. Thankfully, I'm security savvy enough to maintain a regular local backup as well as cloud backup. Meanwhile, on the OTHER computer, there's an incomplete collection of most of the original files. What?!
So Box! You can't 'Sync' worth crap. You're ONLY a backup program. That's all. I like your backup. Your Sync is dangerous and worthless.
