P: I would like to synchronize over LAN/Cable instead of internet

Hi Selondon. What I think scoopz is asking for is exactly what Dropbox already delivers -- sync over the local network if possible, otherwise sync to a server in the cloud. This works without any problems on Dropbox.

But, as is obvious, Adobe's bread and butter is photos and graphics, while Dropbox is pure synching, so it wouldn't be surprising if Adobe isn't able to come up with such a seamless solution.

My main question regarding this is how would you avoid conflict?

If all photos eventually go to the Cloud, would they just not download to Lr Desktop if they have previously LAN synced?

Adobe aren't going to make Lr Mobile LAN Sync only, so would it just require a LAN only button or just some really clever coding?

It's so obviously a requirement, I am just wondering how it is to be implemented considering the LrM/W are less complex than how users may arrange their folders in LrD?

I don't want a physical cable/USB connection I just want to be able to sync over my Local Area Network (LAN) which, in most cases, would be ethernet from desktop to router and then fast 802.1ac wifi from router to iPad Pro.

I spoke in a forum with someone on the LR mobile team last year and he said they had no intention of a wired connection as wires were a thing if the past. Hopefully we can change their mind.

I agree, a Dropbox style sync is the most obvious solution.

There are just lots of scenarios that need to be considered, and they need to make sure the cloud sync is rock solid before adding a bunch of additional variables.

For example, with cloud sync, it only needs to sync the data you actually need to view, whereas LAN sync would need to sync everything you might possibly need, because it couldn't go back and get them later. That has space repercussions on mobile devices. 

Then, if you can do LAN sync, what happens if you have multiple users all trying to work on the same photos at the same time, creating a bunch of conflicts? With a cloud as the center of the universe, everything links back into that, whereas LAN sync would then want to move into multi-desktop sync, so how do you decide which is the master, and on it goes...

From someone who doesn't code myself why is this not a simple task? Compared to say writing code for it to cloud sync ? My gut feeling is that with local sync people may be able to bypass the subscription payment potentially? But if we are forced to cloud sync adobe ensures more people pay?
I'm not against paying I just want to sync locally fast.

I agree with you Greg & co. I regularly travel iPad-only, so it's important for me too, and I voted on the request at release. I'm sure it will come in due course.

I just wanted to check whether it was specifically the lack of LAN sync that Yves felt made it "unusable" or something else. LRM has only ever been cloud-sync (and advertised as such), so I'm wondering why he feels that he's been lied to. Perhaps there's a web page that needs clarifying?

There's no question it's a very valid feature request that would have significant benefits to many users. Not a simple task, however.

Hi Victoria,
When travelling overseas it is quite common to be in a location where the internet is only available in the lobby of the hotel or not at all. Similarly, if you are going to be on a plane for hours, it would be nice to use that down time to cull and edit photos. Being tied to the cloud becomes a major obstacle in those situations and I've stopped taking my iPad on trips as a result.
