Data corruption is the unintended modification of a file or the losing of info which usually occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file can become partially or fully corrupted, so it'll no longer work correctly since its bits shall be scrambled or missing. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. When such a problem occurs and it is not noticed by the system or by an administrator, the data will be corrupted silently and when this happens on a disk drive that is part of a RAID array where the info is synchronized between various drives, the corrupted file shall be duplicated on all of the other drives and the harm will be long term. Numerous commonly used file systems either do not offer real-time checks or do not have high quality ones which can detect an issue before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where substantial volumes of data are stored.

No Data Corruption & Data Integrity in Cloud Website Hosting

The integrity of the data that you upload to your new cloud website hosting account will be ensured by the ZFS file system which we make use of on our cloud platform. Most internet hosting service providers, including our firm, use multiple hard drives to keep content and since the drives work in a RAID, the same info is synchronized between the drives at all times. If a file on a drive becomes corrupted for reasons unknown, yet, it's likely that it will be reproduced on the other drives since alternative file systems do not feature special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every single file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, so the damaged copy will be substituted with a good one from another hard disk drive. Due to the fact that this happens instantly, there is no possibility for any of your files to ever get damaged.
