The process of files getting damaged owing to some hardware or software failure is called data corruption and this is one of the main problems that Internet hosting companies face since the larger a hard drive is and the more info is filed on it, the more likely it is for data to be corrupted. You'll find different fail-safes, yet often the info becomes corrupted silently, so neither the particular file system, nor the administrators detect a thing. As a result, a damaged file will be handled as a regular one and if the hard disk is a part of a RAID, the file will be copied on all other drives. In principle, this is for redundancy, but in practice the damage will be worse. The moment some file gets damaged, it will be partially or completely unreadable, which means that a text file will no longer be readable, an image file will show a random blend of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your site content. Although the most commonly used server file systems have various checks, they are likely to fail to detect some problem early enough or require a vast amount of time to check all files and the hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Web Hosting
We guarantee the integrity of the info uploaded in every web hosting account that is generated on our cloud platform as we use the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption via a unique checksum for each and every file. We shall store your data on a large number of SSD drives which work in a RAID, so the very same files will be available on several places at once. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in case the checksum of any file is different from what it has to be, the file system replaces that file with an undamaged version from some other drive within the RAID. There's no other file system which uses checksums, so it is possible for data to be silently corrupted and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you do not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any probability of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created work with a powerful file system called ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we save all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has saved. When there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since this happens instantly, there is no chance that a damaged copy could remain on our hosting servers or that it can be copied to the other hard drives in the RAID. None of the other file systems include this kind of checks and in addition, even during a file system check after a sudden electrical power failure, none of them can discover silently corrupted files. In contrast, ZFS will not crash after a power failure and the constant checksum monitoring makes a lenghty file system check unneeded.
