The process of files getting damaged resulting from some hardware or software failure is referred to as data corruption and this is among the main problems that web hosting companies face since the larger a hard disk is and the more data is kept on it, the more likely it is for data to become corrupted. You'll find several fail-safes, still often the info becomes damaged silently, so neither the file system, nor the admins notice a thing. Thus, a corrupted file will be handled as a good one and if the hard drive is part of a RAID, that particular file will be duplicated on all other drives. Theoretically, this is for redundancy, but in reality the damage will get worse. Once a file gets damaged, it will be partially or fully unreadable, which means that a text file will no longer be readable, an image file will present a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most frequently used server file systems have various checks, they are likely to fail to identify some problem early enough or require a vast amount of time to be able to check all of the files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Web Hosting

We've resolved the issue of silent data corruption on all of our cloud web hosting servers by using the advanced Z file system, or ZFS. The latter is better than other file systems because it is the only one out there which checks all the files right away by using a checksum - a digital identifier that is unique for each and every file. When you upload content to your account, it'll be stored on several NVMe drives and continually synced between them for redundancy. ZFS regularly examines the checksum of all files and if any file is detected as damaged, it is replaced instantly with a good copy from some other disk. As this happens in real time, there's no risk that a bad file may remain or may be copied on the remaining NVMes. ZFS needs a lot of physical memory in order to perform the real-time checks and the advantage of our cloud web hosting platform is that we employ multiple very powerful servers working together. If you host your websites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you obtain one of our semi-dedicated server solutions, you won't have to be concerned about silent data corruption because we use ZFS - an advanced file system which monitors all 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. That file will be synced between a number of NVMe drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done immediately, so there will be no threat for any part of your content at any time. In contrast, 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 won't detect silently corrupted files, so a bad copy may be replicated on the other drives as well and you could lose critical info. As this isn't the case with ZFS, we are able to warrant the integrity of every single file you upload no matter what.
