The process of files getting damaged as a result of some hardware or software failure is called data corruption and this is one of the main problems that hosting companies face because the larger a hard disk drive is and the more information is placed on it, the more likely it is for data to get corrupted. You'll find a couple of fail-safes, but often the data becomes corrupted silently, so neither the particular file system, nor the admins notice anything. As a result, a corrupted file will be treated as a good one and if the hard disk is part of a RAID, that particular file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will get even worse. When a file gets damaged, it will be partially or fully unreadable, which means that a text file will not be readable, an image file will display a random mix of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your website content. Although the most popular server file systems have various checks, they often fail to find a problem early enough or require an extensive amount of time to check all of the files and the web server will not be functional for the time being.

No Data Corruption & Data Integrity in Cloud Hosting

We have resolved the matter of silent data corruption on all our cloud hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is superior to other file systems as it is the only one in existence that checks all files in real time by employing a checksum - a digital identifier that's 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 the event that any file is detected as corrupted, it's replaced promptly 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 remaining SSDs. ZFS requires a lot of physical memory to execute the real-time checks and the benefit of our cloud web hosting platform is that we work with multiple powerful servers working together. If you host your Internet sites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you obtain one of our semi-dedicated hosting solutions, you will not have to be concerned about silent file corruption since we use ZFS - a high level file system that checks all files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between several SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens instantly, so there will be no danger for any part of your content at any moment. In contrast, alternative file systems execute checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy can be replicated on the other drives as well and you could lose crucial data. Since this isn't the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
