What do I need to watch out for with using dropbox?
I'm the only use so I should be ok for not running both machines, but I appreciate you bringing it to my attention. Yes, I back up often.
Really you just have to be very careful about making sure Lightroom is closed on one computer, and that the changes made on the first one have time to upload to Dropbox and then sync to the other computer before opening Lightroom with that same catalogue.
Dropbox doesn't have the nicest interface for out of sync writes, and as far as I know just does a simple push of the 'newest' file edit to all systems. (At least that is what it appeared to do in all my previous tests) So if you make massive changes to a file on a system that is offline, and then edit it on a second system before the file from the first makes it there, dropbox just looks at it and says "Yep, file on the second system was edited last, time to push that out to everyone, and we'll ignore the minutes/hours/days/weeks of work that went into that other 'old' copy from the first system." I've never seen it throw an error or warning about edit conflicts in any of my testing. (However if anyone knows how to enable that, or if it has changed since I did actual tests awhile back, that would be great to know.)
Lightroom seems to be good at pushing a stream of constant small changes out to the catalog file as it is running, so it is unlikely that you'll do much damage even if you have both computers in front of you at the time you exit out of one and load the other. Where you're most likely to get into trouble is with an unusual event such as having issues with your network or internet connection. Something like having a long power outage where you're on your laptop making edits for awhile, and trying to switch over to the desktop as soon as the power comes back on without realizing that your network is still down or trying to launch Lightroom while dropbox is still syncing the catalogue changes.
I have Lightroom setup to make backup copies of the Catalogue to different folders on an online drive depending on which system was running it at the time. Desktop backups are distinct from the backups created on the laptop, even if they're technically the same working file. Usually try and write a backup every time I exit Lightroom, but so far I have yet to need to resort to them.
I'm also really liking the new face detection system. Still waiting on the backlog of old photos to get processed, but I generate thousands of them shooting sports. Looking like this may prove very useful when someone contacts me and asks if I can send them photos of a player for some special event.
