Immich autobackup fills up iPhone System Data

[sevvlor]

The bug

The Immich backup feature that allows photos to be backed up to the remote server causes the system data on my iPhone 15 Pro Max with iOS 17.6.1 to be filled up completely. This causes the iPhone to notify me with "storage full" notifications.

• Uninstalling the Immich iOS app clears the system data.
• Reinstalling the app with the backup disabled does not cause the System Data to be filled.
• The System Data does not get cleared after a day/hour/week/timeframe.

Image describes the System Data that is filled.

Can you help me check how much data/document storage does the app use?

Can you help me check how much data/document storage does the app use?

It's currently using 35,2MB for documents and data. If you want I can re-enable the backup functionality and report back.

Edit: I have granted it access to the photo library and it shot up to 11GB and is increasing.

[alextran1502]

@sevvlor Thanks, this is indeed an issue when the size inflated that much. Just to confirm that you are only seeing the size increase when running backup, correct?

• How many photos/videos do you have on your phone?
• How many assets do you have on your Immich server?

[sevvlor]

It happened again. 118G of storage that's listed as System Data. To answer your question:

on my phone: 15772 photos and 520 videos: 16292 total
on Immich: 20152 photos and 687 videos : 20839 total

Edit: I only see it when its backing up or when the feature is enabled. The data does not get removed after the backup has finished or gets turned off.

This graph also shows something interesting. Around 12 the storage gets filled rapidly. Bear in mind that the phone checks in every few hours so it might've taken an hour to fill.

@alextran1502 yes, I am.
