Data corruption is the accidental change of a file or the loss of info which usually occurs during reading or writing. The reason could be hardware or software failure, and consequently, a file could become partially or entirely corrupted, so it'll no longer work correctly because its bits shall be scrambled or missing. An image file, for instance, will no longer present an actual image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. In the event that such an issue occurs and it isn't recognized by the system or by an administrator, the data will become corrupted silently and in case this happens on a disk drive which is part of a RAID array where the data is synced between various different drives, the corrupted file shall be duplicated on all of the other drives and the harm will be permanent. A large number of popular file systems either do not offer real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a common problem on internet hosting servers where huge amounts of info are stored.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the information uploaded in each and every shared hosting account which is created on our cloud platform because we employ the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption thanks to a unique checksum for every single file. We shall store your info on multiple NVMe drives that function in a RAID, so exactly the same files will exist on several places at once. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and if the checksum of any file is different from what it needs to be, the file system swaps that file with a healthy copy from a different drive inside 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 that can never happen on a server running ZFS, you won't have to worry about the integrity of your information.
