If a tweak you were using has been storing data in an unorthodox place, and you create a backup of this data, when you restore the phone you might never be able to access (or delete) said data again.This might not be a huge amount of data and pose little problem, or it might be a lot of temporary files that eats a good portion of your 16GB i Phone’s memory.
