Data corruption is the unintentional transformation of a file or the losing of information that usually occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file could become partially or completely corrupted, so it will no longer work correctly since its bits shall be scrambled or missing. An image file, for instance, will no longer present a true image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etc. In case such a problem appears and it isn't noticed by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive that's a part of a RAID array where the information is synced between different drives, the corrupted file will be reproduced on all of the other drives and the harm will be long term. Numerous 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 very common issue on internet hosting servers where large volumes of info are stored.
No Data Corruption & Data Integrity in Shared Website Hosting
The integrity of the data which you upload to your new shared website hosting account shall be ensured by the ZFS file system which we take advantage of on our cloud platform. Most web hosting providers, including our company, use multiple HDDs to store content and because the drives work in a RAID, the same data is synchronized between the drives at all times. When a file on a drive gets corrupted for some reason, yet, it's more than likely that it will be copied on the other drives since other file systems do not offer special checks for this. Unlike them, ZFS works with 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 shall be replaced with a good one from another hard disk. Since this happens right away, there's no risk for any of your files to ever get corrupted.
