No Data Corruption & Data Integrity

Data corruption is the unintended modification of a file or the loss of information that usually occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file may become partially or entirely corrupted, so it will no longer function correctly as its bits shall be scrambled or lost. An image file, for instance, will no longer show an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. If this kind of an issue appears and it is not noticed by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that's a part of a RAID array where the info is synchronized between various drives, the corrupted file shall be duplicated on all the other drives and the damage will be permanent. A large number of commonly used file systems either don't feature real-time checks or don't have good ones which can detect an issue before the damage is done, so silent data corruption is a very common issue on hosting servers where huge volumes of data are stored.
