Data corruption is the damage of info caused by various software or hardware failures. Once a file gets corrupted, it will no longer work accurately, so an app will not start or will give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for web hosting servers as failures are very likely to happen on larger hard drives where substantial volumes of information are kept. When a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as a good one and it will be copied on all of the drives, making the harm permanent. A lot of the file systems that operate on web servers nowadays often are not able to locate corrupted files in real time or they need time-consuming system checks through which the server is not functioning.

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 take advantage of on our cloud platform. Most web hosting service providers, like our firm, use multiple hard drives to keep content and since the drives work in a RAID, exactly the same data is synchronized between the drives at all times. If a file on a drive gets damaged for some reason, however, it is likely that it will be duplicated on the other drives as alternative file systems do not have special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each and every file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, so the bad copy shall be replaced with a good one from a different hard drive. Due to the fact that this happens instantly, there is no possibility for any of your files to ever be damaged.
