Numerous users have been facing data loss issues post the iOS 9 upgrade, due to various installation problems such as the update failing to install or the device booting into recovery mode or user data being deleted due to lack of sufficient installation space. Fortunately, affected users can reclaim their lost data by using backup files created via iTunes or iCloud, before initiating the iOS 9 update.
One can make use of professional iOS data recovery tools such as PhoneRescue for this purpose or use traditional data recovery methods via iTunes or iCloud Backup and Restore feature. IBTimes UK brings you a detailed step-by-step guide to accomplish this feat by using either iTunes or iCloud backup:

Step 4: Tap Restore from iCloud Backup and then sign into iCloud with your own Apple ID.
Step 5: Select the iCloud backup file you want to restore from, and wait for the contents to be copied to your iDevice. The process may last a few minutes to some hours, depending on the size of your iCloud backup file and the speed of your network.
