Data corruption is the accidental modification of a file or the loss of info which often occurs during reading or writing. The reason could be hardware or software malfunction, and because of this, a file may become partially or completely corrupted, so it'll no longer work correctly since its bits will be scrambled or lost. An image file, for instance, will no longer present a real image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In case this kind of a problem appears and it isn't noticed by the system or by an admin, the data will become corrupted silently and in case this happens on a drive which is part of a RAID array where the information is synced between different drives, the corrupted file will be copied on all other drives and the damage will be permanent. A number of popular file systems either don't offer real-time checks or do not have high quality ones that can detect an issue before the damage is done, so silent data corruption is a common matter on internet hosting servers where substantial amounts of data are kept.

No Data Corruption & Data Integrity in Shared Web Hosting

The integrity of the data which you upload to your new shared web hosting account shall be ensured by the ZFS file system which we work with on our cloud platform. The majority of web hosting providers, like our company, use multiple HDDs to store content and considering that the drives work in a RAID, identical data is synchronized between the drives at all times. When a file on a drive gets corrupted for some 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 uses a digital fingerprint, or a checksum, for each and every file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the bad copy will be substituted with a good one from another hard drive. Because this happens in real time, there is no risk for any of your files to ever be corrupted.
