Immich uploads duplicates of pictures

[carmine drum]

I installed the 1.54 version and updated to the new server version and now it wants to backup the whole library again

[pseudo nymph]

Did you install from different source? Apk, fdroid, PlayStore?

[carmine drum]

I installed from play store instead of Fdroid since in F droid it was still at 1.53 and in Play store it was already 1.54

I wanted the versions of server and client to match

I see so this is not something that should be done?

[pseudo nymph]

Yes if you use one installation method you should stick to it since there is a device id which is used to query the uploaded vs not uploaded asset. The device id will be different on different instruction methods

I don’t like how the device id changes but this is the limitation we have to work with

[carmine drum]

Alright

Thanks for the info

Oh, but could you update the f droid version then?

Just a quick question, does that mean that if I switch devices and move all my photos from old phone to new phone, it will assume all the photos haven't been backed up and will start uploading them again?

[carmine drum]

Thats a good question. I guess since they are backed up already, you dont have to copy them to your new phone though.

Anyways, I wonder if a per account solution could be done by comparing the sha256sum of the uploaded pictures?

[vestal hearth]

I generally use a software like Samsung Smart Switch to copy apps and data to a new phone. And apps like WhatsApp download the images automatically when logged into a new phone. So I guess the current system can cause issues in this scenario.

[carmine drum]

Yeah I get it. Tbh, it would make sense to be able to.have the uploads compare the uploaded.pictures, no matter from.which phone it comes. Why is the device ID used even? couldn't a randomly generated one be used that can be saved and copied.to a new phone? curious

[timber scaffold]

according to github issues they're working on a feature that just hashes the photos

so even if you switch phones there won't be dupes

[pseudo nymph]

trade off of complexity would be the answer

[carmine drum]

thats what I was meaning

[carmine drum]

well lets see where it goes then

[pseudo nymph]

yeah there is PR opened for client side hashing, which eventually will be fix for this issue

[dusky thistle]

Sorry to dig up old question. Is the client side hashing merged? I am on server 1.103.1 and iOS app v1.103.0. I uninstalled the app and re-installed it again. It's uploading the entire library again. I think it's no adding the duplicate photos to the library but it goes through the upload before deciding that it's a duplicate. It would be good to skip the upload if the image with hash already exists.

It is not yet. Still being worked on. https://github.com/immich-app/immich/issues/1553
