The process of files getting corrupted caused by some hardware or software failure is known as data corruption and this is among the main problems that Internet hosting companies face since the larger a hard disk is and the more info is kept on it, the much more likely it is for data to get corrupted. There are various fail-safes, yet often the data gets corrupted silently, so neither the particular file system, nor the administrators detect a thing. As a result, a corrupted file will be treated as a regular one and if the hard drive is part of a RAID, the file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in reality the damage will get worse. The moment some file gets corrupted, it will be partially or fully unreadable, therefore 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 feature various checks, they are likely to fail to detect some problem early enough or require an extensive amount of time to be able to check all of the files and the hosting server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Web Hosting

We have dealt with the issue of silent data corruption on all our shared web hosting servers by using the cutting-edge Z file system, or ZFS. The latter is superior to other file systems because it is the only one in existence which checks all files in real time by employing a checksum - a digital identifier which is unique for each file. When you upload content to your account, it'll be stored on several NVMe drives and regularly synced between them for redundancy. ZFS constantly compares the checksum of all files and in the event that any file is detected as corrupted, it's replaced promptly with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be duplicated on the other NVMes. ZFS requires plenty of physical memory to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple very powerful servers working together. If you host your Internet sites with us, your info will be undamaged no matter what.
