The process of files being corrupted because of 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 data is stored on it, the more likely it is for data to be corrupted. You will find a couple of fail-safes, still often the information is damaged silently, so neither the file system, nor the admins see anything. Thus, a corrupted file will be handled as a good one and if the hard disk drive is a part of a RAID, that particular file will be duplicated on all other disk drives. In theory, this is done for redundancy, but in practice the damage will be worse. Once some file gets corrupted, it will be partially or completely unreadable, which means that a text file will no longer be readable, an image file will display a random mix of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your content. Although the most popular server file systems have various checks, they often fail to detect some problem early enough or require a vast amount of time in order to check all the files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Website Hosting

We've resolved the problem of silent data corruption on all our website hosting servers by using the advanced Z file system, or ZFS. The latter is superior to other file systems as it is the only one on the market that checks all the files immediately by employing a checksum - a digital identifier that is unique for each file. When you upload content to your account, it will be stored on several SSD drives and continually synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and when 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 damaged file may remain or may be copied on the other SSDs. ZFS requires a lot of physical memory in order to execute the real-time checks and the advantage of our cloud hosting platform is that we take advantage of multiple very powerful servers working together. If you host your websites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility of files getting damaged silently due to the fact that the servers where your semi-dedicated hosting account will be created employ a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. Since we keep all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. If there's a mismatch, the damaged 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 can remain on our servers or that it could be copied to the other hard drives in the RAID. None of the other file systems employ this type of checks and what's more, even during a file system check after a sudden electrical power failure, none of them can detect silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unnecessary.
