Data corruption is the damage of information caused by various software or hardware failures. After a file gets corrupted, it will no longer work accurately, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, which makes it a significant problem for hosting servers as problems are much more likely to occur on bigger hard disk drives where significant volumes of info are stored. When a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the bad file will be treated as an ordinary one and will be copied on all the drives, making the harm permanent. A lot of the file systems which run on web servers today often are not able to discover corrupted files immediately or they need time-consuming system checks during which the server isn't operational.

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 guaranteed by the ZFS file system that we use on our cloud platform. The majority of hosting service providers, including our firm, use multiple hard drives to store content and because the drives work in a RAID, the exact same data is synchronized between the drives at all times. If a file on a drive gets corrupted for reasons unknown, yet, it is likely that it will be duplicated on the other drives as other file systems do not include special checks for that. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the bad copy will be substituted with a good one from another drive. Because this happens instantly, there is no possibility for any of your files to ever get corrupted.
