Data Corruption

Data corruption is the damage of data due to various hardware or software failures. After a file gets damaged, it will no longer function correctly, so an app will not start or will give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, that makes it a serious problem for hosting servers as failures are more likely to occur on larger in size hard drives where considerable volumes of info are located. If a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is likely that the bad file will be treated as a good one and it'll be duplicated on all drives, making the harm permanent. A huge number of the file systems that operate on web servers these days often are not able to find corrupted files immediately or they need time-consuming system checks during which the server is not working.
