Importing Old Pictures - Asset Upgraded but can't find the original asset ?

[R-Nabil]

Hello,

I've been trying to use Immich-Go (dry-run mode) with old pictures I have to figure out whether these were already on my immich or not. I'm getting several messages like :

server's asset upgraded with the input | file=IMAG0308.jpg reason="An asset with the same name:"IMAG0308.jpg" and date:"2011-02-08 19:11:29" but with smaller size:182.6 KB exists on the server. Replace it." time="2024-09-06T08:13.09 UTC"

But if I go on the server, I do not find any asset named like this, or any asset on that date in general.

Am I missing something ?

Thanks

The name IMAG0308.jpg comes from immich. (not the physical file name you may find on the server's disk)

Still. There is no asset for that mentioned date at all on Immich. Like really none at all

A side effect of the -dry-run option? Maybe the file is duplicated in your input, and when immich-go finds it a second time, it believes it has already uploaded it.

Ah. Interesting hypothesis. It is indeed likely I have 2 copies of the same asset, one that was downsized by Google most likely, and the original one. Would you have a suggestion on how to test this out ? I could always write a short script to go through all my assets and find the ones for that given date. Also, assuming this is the case, what does the total number of asset uploaded means ? Say I have only these 2 duplicates. It uploads the lower quality first then upgrades it with the higher quality. The total upload would be 2 even though Immich would only have 1 extra asset right ? Thank you for your time and help

How it's possible to have the original and the downgraded asset in the same takeout? I haven't explicitly tested this case.
Or maybe, you are not importing a takeout archive.

Anyway, the -dry-out behavior looks good: the 1st encountered file is uploaded, than when the best quality version is found, immich-go should replace the downgraded quality image of the server by the better one.

It's just a mess of old pictures inconsistently kept in various different folder merged and un merged constantly. Just a mess.

I'm pretty sure most of them are already on Immich. Problem is there is quite a bit of them that are not mine and I'm trying to find a programmatic/systematic way to find out about this.

Immich-go cares of duplicates files having same name, and same date of capture.
Immich cares about true binary duplicates, eg files having the same content, byte by byte.
And at the last resort, Immich has introduced a dedup functionality.
