Data corruption is the accidental transformation of a file or the loss of info that often occurs during reading or writing. The reason could be hardware or software failure, and as a result, a file may become partially or entirely corrupted, so it will no longer work correctly as its bits will be scrambled or lacking. An image file, for example, will no longer show a true image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. If this kind of a problem occurs and it is not recognized by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive which is part of a RAID array where the info is synchronized between various drives, the corrupted file will be copied on all other drives and the harm will become permanent. A large number of widely used file systems either do not have real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common matter on web hosting servers where large amounts of data are stored.
No Data Corruption & Data Integrity in Website Hosting
We guarantee the integrity of the data uploaded in every single website hosting account which is created on our cloud platform because we work with the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption through a unique checksum for every single file. We'll store your information on a large number of SSD drives that operate in a RAID, so the exact same files will be available on several places at once. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file is different from what it should be, the file system replaces that file with an undamaged copy from a different drive from the RAID. There's no other file system that uses checksums, so it's possible for data to get silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your info.
