The process of files getting corrupted owing to some hardware or software failure is known as data corruption and this is one of the main problems that hosting companies face because the larger a hard drive is and the more information is stored on it, the more likely it is for data to get corrupted. You'll find different fail-safes, still often the info is corrupted silently, so neither the file system, nor the administrators detect anything. Consequently, a corrupted file will be treated as a standard one and if the hard disk drive is part of a RAID, that particular file will be duplicated on all other drives. In theory, this is for redundancy, but in reality the damage will get worse. The moment some file gets damaged, it will be partially or completely unreadable, so a text file will not be readable, an image file will present a random mix of colors in case it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your content. Although the most commonly used server file systems have various checks, they frequently fail to detect some problem early enough or require a long period of time to be able to check all the files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Website Hosting

We've resolved the problem of silent data corruption on all of our cloud website hosting servers by using the leading-edge Z file system, or ZFS. The latter is better than other file systems because it is the only one on the market that checks all of the files right away by using a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and frequently synced between them for redundancy. ZFS constantly analyzes the checksum of all files and in case any file is detected as corrupted, it is replaced quickly with a good copy from another disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the rest of the SSDs. ZFS requires lots of physical memory to perform the real-time checks and the advantage of our cloud website hosting platform is that we take advantage of multiple powerful servers working together. If you host your sites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any possibility of files getting damaged silently because the servers where your semi-dedicated server account will be created work with a powerful file system named ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As we save all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has stored. If there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and since this happens instantly, there is no chance that a corrupted copy could remain on our servers or that it could be copied to the other hard disks in the RAID. None of the other file systems employ this kind of checks and what's more, even during a file system check after a sudden power failure, none of them can find silently corrupted files. In comparison, ZFS won't crash after a power failure and the continual checksum monitoring makes a time-consuming file system check obsolete.
