Data corruption is the accidental change of a file or the loss of info which often occurs during reading or writing. The reason could be hardware or software malfunction, and due to this fact, a file may become partially or fully corrupted, so it will no longer work properly because its bits will be scrambled or missing. An image file, for instance, will no longer display 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. In case such an issue appears and it is not identified by the system or by an admin, the data will be corrupted silently and if this happens on a disk drive that's a part of a RAID array where the information is synchronized between various different drives, the corrupted file shall be duplicated on all of the other drives and the harm will become long term. A number of widely used file systems either don't have real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a rather common problem on hosting servers where large amounts of information are kept.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data that you upload to your new shared web hosting account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most web hosting providers, like our company, use multiple HDDs to keep content and considering that the drives work in a RAID, identical information is synchronized between the drives at all times. In case a file on a drive gets damaged for reasons unknown, however, it is very likely that it will be reproduced on the other drives as other file systems do not offer special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, so the bad copy shall be substituted with a good one from another hard disk drive. Because this happens immediately, there's no possibility for any of your files to ever be damaged.
