For example, I have 2.9G files in Camera Roll, these files also exist in the backup, so I can remove these files from my iPhone, then the free space on my iPhone will be 4.0G, so I can restore the backup with no problem. 2. Do not do a full restore, only restore the contents that we want, for example, select Particular Restore in restore option window, then only check Contacts and Messages to only restore SMS messages and address book:
NOTICE: For some iOS version, do a particular restore may cause Camera Roll files remove from your device. So if Camera Roll files not exist in the backup, before you do particular restore we recommend you backup your device to another place: select the device in Devices window of iBackupBot, then click Back Up Now in right side window and select Back up to another folder in backup option window and click OK button.
