Data corruption is the accidental change of a file or the loss of info that often occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file could become partially or fully corrupted, so it'll no longer function correctly because its bits will be scrambled or missing. An image file, for instance, will no longer present 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, etc. When this kind of a problem occurs and it is not found by the system or by an admin, the data will be corrupted silently and if this happens on a drive that is part of a RAID array where the info is synchronized between different drives, the corrupted file shall be duplicated on all other drives and the harm will be permanent. A number of widespread file systems either do not offer real-time checks or do not have good ones which will detect a problem before the damage is done, so silent data corruption is a common matter on hosting servers where substantial volumes of data are stored.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting account will be guaranteed by the ZFS file system which we use on our cloud platform. The majority of web hosting suppliers, like our company, use multiple HDDs to keep content and since the drives work in a RAID, the exact same information is synchronized between the drives all of the time. When a file on a drive becomes damaged for reasons unknown, however, it's very likely that it will be reproduced on the other drives as other file systems don't have special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the bad copy shall be substituted with a good one from a different hard disk drive. Since this happens right away, there's no possibility for any of your files to ever be corrupted.
