so i know that some, or let's say nearly all, files are backed up on iOS.
I know how to prevent them from being backed up.
To maybe save unnecessary work i wanted to know if the content of
containerURLForSecurityApplicationGroupIdentifier:
is being backed up too?
I couldn't find anything specific about the group containers in the File System Basics from apple. In NSFileManager it is said that the directories are stored in ~/Library/Group Container/. In File System Basics it is written that all subdirectories of Library are backed up by iTunes. Does this now also mean that the content of my Group Container is also backed up or maybe not?
Maybe someone of you already has experience with that and can exactly tell me what's done with the content of the Group Container.

Your iPhone, iPad, and iPod touch backups only include information and settings stored on your device. They do not include information already stored in iCloud such as Contacts, Calendars, Bookmarks, Notes, Reminders, Voice Memos4, Messages in iCloud, iCloud Photos, and shared photos.
As cache data is not backed up by iTunes and iCloud, the Backup and Purge Cache Data task creates a backup copy of the cache folders before purging begins. These time stamped backup folders are in the regular cache directory.
The backup will be located in /Users/<YOUR_USERNAME>/Library/Application Support/MobileSync/Backup/. The backup folder is named with the device's UDID. You can check the timestamp on the folder to find the latest one. You can also use iTunes to locate the backup file, as both Configurator and iTunes store these files.
The backup contains: All your settings. Application data except data marked as "cache" or not to sync.
As an iOS developer myself this is an important question. After some hunting, I found this radar:
AppGroup folder does not backed up (sic) via standard iCloud/iTunes backup procedure
This was reported as a duplicate of rdar://18396036 (Open) but it cannot be found.
Responses from Apple:
If this issue is still occurring, please include any relevant logs, and or a test case with your update. (Oct 30, 2014)
and
Engineering has determined that your bug report is a duplicate of another issue and will be closed (Nov 12, 2014).
It sounds like the intended functionality is that app group folders should be backed up, and there may have been a bug in iOS 8.0 preventing this which is fixed in iOS 8.1.
