Data corruption is the accidental modification of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software fail, and as a result, a file can become partially or entirely corrupted, so it will no longer function properly because its bits will be scrambled or lost. An image file, for instance, will no longer present an accurate image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In case this kind of an issue occurs and it is not noticed by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive that's part of a RAID array where the info is synchronized between various different drives, the corrupted file will be reproduced on all of the other drives and the harm will become permanent. Numerous frequently used file systems either do not feature real-time checks or don't have high quality ones which 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 Website Hosting
The integrity of the data that you upload to your new shared website hosting account shall be ensured by the ZFS file system that we use on our cloud platform. Most web hosting service providers, including our firm, use multiple hard drives to store content and because the drives work in a RAID, identical information is synchronized between the drives all the time. If a file on a drive gets corrupted for reasons unknown, however, it's likely that it will be duplicated on the other drives as other file systems do not include special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy shall be substituted with a good one from a different hard disk. Because this happens right away, there is no risk for any of your files to ever get corrupted.
