The process of files getting corrupted as a result of some hardware or software failure is referred to as data corruption and this is one of the main problems that web hosting companies face since the larger a hard disk is and the more information is kept on it, the much more likely it is for data to be corrupted. There're different fail-safes, but often the info becomes corrupted silently, so neither the particular file system, nor the administrators see anything. Consequently, a bad file will be handled as a good one and if the hard disk is a part of a RAID, that file will be copied on all other drives. Theoretically, this is done for redundancy, but in practice the damage will be worse. The moment a file gets corrupted, it will be partially or fully unreadable, so 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 sacrificing your site content. Although the most commonly used server file systems feature various checks, they often fail to find a problem early enough or require a long amount of time to check all of the files and the 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 our cloud web hosting servers by using the amazing Z file system, or ZFS. The latter is better than other file systems as it is the only one on the market which checks all of the files in real time by employing a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it will be stored on several NVMe drives and continually synced between them for redundancy. ZFS regularly examines the checksum of all files and in case any file is detected as damaged, it's replaced right away with a good copy from another disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the remaining NVMes. ZFS requires a lot of physical memory in order to perform the real-time checks and the benefit of our cloud website hosting platform is that we work with multiple powerful servers working together. In case you host your websites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you purchase one of our semi-dedicated server plans, you won't have to be concerned about silent data corruption since we use ZFS - an advanced file system that keeps track of all the files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between several NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no risk for any part of your content at any time. In comparison, other file systems perform checks after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a corrupted copy could be replicated on the rest of the disks as well and you can lose precious info. Since this is not the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
