Data corruption is the accidental change of a file or the loss of information that often occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file may become partially or entirely corrupted, so it'll no longer work correctly since its bits shall be scrambled or missing. An image file, for instance, will no longer show a true image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. When this kind of an issue appears and it is not recognized by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that is part of a RAID array where the information is synchronized between different drives, the corrupted file will be duplicated on all the other drives and the damage will be permanent. A number of frequently used file systems either do not feature real-time checks or do not have high quality ones which will detect an issue before the damage is done, so silent data corruption is a common matter on hosting servers where substantial volumes of info are kept.
No Data Corruption & Data Integrity in Cloud Web Hosting
The integrity of the data that you upload to your new cloud web hosting account will be ensured by the ZFS file system that we make use of on our cloud platform. The vast majority of hosting service providers, like our firm, use multiple HDDs to keep content and since the drives work in a RAID, identical info is synchronized between the drives at all times. When a file on a drive is damaged for whatever reason, yet, it is likely that it will be copied on the other drives as alternative file systems do not have special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each and every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the bad copy will be replaced with a good one from another hard disk drive. As this happens instantly, there's no possibility for any of your files to ever be corrupted.
