AppGroup folder does not backed up via standard iCloud/iTunes backup procedure

Number:rdar://18750178 Date Originated:18 sep 2014
Status:Duplicate of 18396036 (Open) Resolved:No
Product:iOS Product Version:8.0
Classification:Data loss Reproducible:
I've implemented a widget extension which is working with CoreData. Since any extension cannot access to host app sandbox i've placed my Persistent Store in AppGroup folder. After this both widget and host app correctly worked with data but later I've found that I lost all data after backing up and restoring all data from device.

Steps to Reproduce:
1. setup your entitlements to work with app groups.
2. add your core data persistent store to the app group folder.
3. save some data to the persistent store, make sure that it saved on disk
4. backup all your data via iTunes or iCloud standard backup.
5. restore the backup created on step 4.

Expected Results:
The data saved in app group folder would be restored

Actual Results:
The data saved in app group folder lost
