Onedrive sizes differ on files uploaded by Onedrive iOS client

[Ole (Ole Frost)]

Yes, it looks like a known OneDrive limitation with Live Photos from iOS. You can find some additional infomation here:

Can't mount '.heic' (photo-video) files from onedrive

@asdffdsa Good question, I guess the answer is yes. @Andrew_Xxx: It looks like the files are Live Photos uploaded from the iOS OneDrive App. If so, then the issue is most likely due to OneDrive’s partial support of Live Photos. Upload and storage from the iOS app were introduced in December 2020. The remaining implementation is still work-in-progress and this introduces some “surprising” situations when mounting and synchronizing - also in the native OneDrive client on Windows.

I work around the limitation by using --ignore-size when syncing and --download when checking. Please note that this workaround only syncs the still-picture not the movieclip - and it relies on modification dates being correctly updated.

Confusingly I have the same setup to backup my Wife's Onedrive account, she also uses the iOS Onedrive client to upload photos, however rclone check does not lead to any "sizes differ" errors, when run on her account.

I guess your wife has disabled Live Photos - or an old iPhone.
