According to a Google research, approximately 8% of all the hard disks crash within the first two years of usage. Such devices do not have a long life, thus the data stored in them is not entirely secure. The device can get corrupted anytime and the company can lose all the data stored on that device. Such scenarios are avoided when online storage facilities are used. The storage providers have advanced contingency plans in case any issue occurs. Usually the storage providers have multiple copies of data which almost makes it impossible to lose any data that has been backed up.
