You should really prove that your restore procedure work correctly.
If something is wrong with either your backup files or your procedures (backup or restore), then you may not be able to restore your data.
You will be relying upon a successfull restore then, and it will be too late to resolve any problems without posible loss of data.
Test your backup and restore procedures fully to prove a full restore is possible with the methods you use, don't just "guess" it will work fine.
