Hi
Is it possible not to download the photos of shared albums when using the --skip-shared-albums option?

My usecase is the following: I have an automatic backup of the photos taken with my smartphone in original quality with an app into my NAS. Since I do my sorting & deleting from Google Photos, I'm looking to "synchronise" my local copy with the "truth" which is my Google Photos referential (I'm looking into using the --compare-folder option) but first I need a proper mirror of Google Photos into my NAS of ONLY my photos and my albums .. not shared albums or other people's photos ...

I hope I was clear

As far as I recall, --skip-shared-albums works as you require. I don't use it on my own library but I do have a system test that verifies that it works (at least on the test account).

Using --compare-folder successfully may be pretty hard. It is probably over complicated by my attempts to cope with cameras from the 90s that frequently used the same filenames and often trashed any metadata. That's why I deprecated it.

Best of luck!

Sure I'll verify against my account (which has many shared albums). I'll get back to you this weekend hopefully.

Logging of tests

using 2023 photos only.
According to Google Photos Web I have:

  • 1940 photos
  • 7 albums (one of which is auto)
  • 2 named shared albums
  • 1 shared album contains 145 photos not mine
  • CORRECTION: there is a 2nd shared album with 45 photos not mine
  • 1 shared album contains 15 mine, 1 not mine CORRECTION: this is a unamed album and does not count
  • there are other unamed shared folders (which should be ignored - TODO verify this)

Test 1 - with no shared

Hmm - a links folder was created for every album in my library - but only files dated past 2023 are linked (so that is a lot of empty folders)

@rui-nar I don't have any immediate answers. But I now have two folders of files to do a detailed investigation with. I have to run now but will get back to this later today.

@gilesknap
Copy link

OK - I do have an answer for the 1577 vs 1940. This was just because I ran and aborted gphotos-sync in that folder before the test and it had already started indexing when I aborted (I wanted to restart with --progress). You can see the correct numbers in Test 2.

back in a couple of hours.

with-shared downloaded an extra 2130-1940 = 190 files whereas I thought I had 146 shared files.

listing the files in the extra album folders that appear in albums/2023 gives 227 extra files.

Neither of these figures add up.

drwxr-xr-x 2 giles dialout  4096 May 16 15:28 '0326 Hockney in Kings X'

The first above is an auto generated album (whch apparently counts as a shared one even though its only in my library) so it contains links to pre-existing photos and can be ignored.

Second is fully shared with 145 images
Third is fully shared with 42 images

This adds up to 187 images extra which is 3 less than reported in the log (so the same 3 that the non-shared sync did probably).

Now checking the difference between actual photos downloaded in each case:

(venv) [giles@ws1 no-shared]$ find photos/ -type f | wc
   1943    1960   69317
(venv) [giles@ws1 no-shared]$ cd ../with-shared/
(venv) [giles@ws1 with-shared]$ find photos/ -type f | wc
   2130    2189   74915
(venv) [giles@ws1 with-shared]$

2130 - 1943 = 187 which is exactly right.

EDIT: forgot to say that this tallies with the photo count in these 2 albums in the Web GUI

Final Synopsis

For my library the 2023 shared/no-shared albums do behave as expected with 187 less photos when using --skip-shared-albums.

Things to note:

  • The code reports downloading an extra 3 files when scanning (non-shared) albums and I do see those extra 3 in the local file count. This is probably one of the google API bugs where not all photos are delivered initially with a global scan see Google API Bugs #119. This could do with further investigation (but I doubt Google will respond to a new ticket on this)
  • There is confusion over what entails a shared album. Google's own creations show up as shared albums but groups of photos shared without creating a shared album do not.
  • gphotos-sync does scan all albums (of correct category shared/non-shared) and create empty folders for those whose contents don't match the date filter - it might be nice to fix that.

@rui-nar These tests were run against the main branch.

Let me know your results.

hey @gilesknap
I have to apologise Giles, I ran all the tests you did and I have the SAME results then you. So I re-ran all my previous commands (which I store in a text file) and all results were in line with expectations. I cannot explain this !!!
I know I upgraded the version to the latest at some point in time but I was sure that I had re-tested everything.

So sorry for having wasted your time.

Btw, the --compare-folder worked flawlessly even if I took some time to understand that the differences I was seeing were archived pictures in GPhotos which I can't seem to filter out in the Google Photos search.

Anyways. Awesome project !! Almost able to fulfill my wife's usecase ;)

Well it is possible that you simply got inconsistent behaviour from the Google API. I was reasonably convinced that this might have been broken so its good to have verified it properly.

Regarding the archived photos - there is a gphotos-sync option that is supposed to include them --archived. Otherwise they are not supposed to be included. Is that not your experience (this is probably for a different issue if you want to open one)
