The process of files being corrupted because of some hardware or software failure is referred to as 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 stored on it, the much more likely it is for data to get corrupted. You'll find different fail-safes, still often the information gets damaged silently, so neither the file system, nor the admins notice anything. Thus, a corrupted file will be treated as a good one and if the hard disk is a part of a RAID, that file will be copied on all other drives. In theory, this is done for redundancy, but in reality the damage will be worse. Once some file gets damaged, it will be partly or completely unreadable, therefore a text file will no longer be readable, an image file will display a random combination of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your website content. Although the most well-known server file systems include various checks, they are likely to fail to detect some problem early enough or require a long period of time in order to check all of the files and the hosting 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 our cloud hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one out there that checks all of the files immediately by employing 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 NVMe drives and continually synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and when any file is detected as damaged, it is replaced right away 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 duplicated on the remaining NVMes. ZFS needs a lot of physical memory to perform the real-time checks and the benefit of our cloud web hosting platform is that we use multiple very powerful servers working together. If you host your websites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you buy one of our semi-dedicated server solutions, you won't have to be concerned about silent file corruption since we use ZFS - an advanced file system that keeps track of all the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between multiple NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no threat for any part of your content at any moment. By comparison, all of the other file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy may be replicated on the rest of the disks as well and you can lose crucial info. As this is not the case with ZFS, we are able to guarantee the integrity of each and every file you upload no matter what.
