Data corruption is the accidental transformation of a file or the loss of info that usually occurs during reading or writing. The reason could be hardware or software malfunction, and because of this, a file can become partially or completely corrupted, so it will no longer work correctly because its bits will be scrambled or missing. An image file, for instance, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. If such a problem occurs and it isn't recognized by the system or by an admin, the data will get corrupted silently and if this happens on a disk drive that's part of a RAID array where the data is synced between various drives, the corrupted file will be replicated on all the other drives and the harm will become permanent. Many widely used file systems either do not have real-time checks or don't have high quality ones that can detect an issue before the damage is done, so silent data corruption is a common matter on internet hosting servers where huge volumes of data are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

If you host your websites in a shared web hosting account with our firm, you don't have to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform employs the leading-edge ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for every single file. All the information that you upload will be saved in a RAID i.e. simultaneously on many NVMes. All of the file systems synchronize the files between the separate drives with this kind of a setup, but there's no real warranty that a file will not be corrupted. This could happen throughout the writing process on any drive and after that a corrupted copy may be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all of the drives instantly and in case a corrupted file is found, it's swapped with a good copy with the correct checksum from another drive. In this way, your information will continue to be intact no matter what, even if a whole drive fails.
