You do not have backups until you have tested the restore. Typically, I restore the production backups to the test environment. This way test gets up to date data and the backup restores are tested.

I have so many stories of data loss from many years working, that I do nothing without backups. From fat finger deletes to raid card batteries failing to multiple disks in the raid array failing at the same time. Data will be lost at some time with the only recovery method being a backup.
