Data corruption is the damage of info because of various hardware or software fails. After a file is corrupted, it will no longer work properly, so an application will not start or will give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, which makes it a significant problem for web hosting servers as problems are much more likely to occur on larger hard drives where considerable volumes of info are placed. In case a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is more than likely that the damaged file will be treated as a regular one and will be duplicated on all of the drives, making the damage permanent. A lot of the file systems which operate on web servers these days often are not able to find corrupted files immediately or they need time-consuming system checks during which the server isn't operational.

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 that we make use of on our cloud platform. The vast majority of web hosting service providers, like our company, use multiple hard drives to keep content and since the drives work in a RAID, identical data is synchronized between the drives all of the time. If a file on a drive is damaged for reasons unknown, yet, it's more than likely that it will be reproduced on the other drives as alternative file systems do not include special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, so the damaged copy will be swapped with a good one from a different hard disk drive. As this happens instantly, there is no possibility for any of your files to ever get damaged.
