No Data Corruption & Data Integrity
See what No Data Corruption & Data Integrity is and how it can be beneficial for the files inside your web hosting account.
The process of files being damaged as a consequence of some hardware or software failure is known as data corruption and this is one of the main problems which hosting companies face as the larger a hard disk drive is and the more info is filed on it, the much more likely it is for data to get corrupted. There're different fail-safes, but often the info is damaged silently, so neither the file system, nor the administrators detect anything. Because of this, a corrupted file will be handled as a good one and if the hard drive is part of a RAID, that file will be duplicated on all other disk drives. In theory, this is done for redundancy, but in reality the damage will be even worse. The moment some file gets damaged, it will be partly or fully unreadable, therefore a text file will no longer be readable, an image file will show a random combination of colors if 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 include various checks, they often fail to find a problem early enough or require a long amount of time in order to check all of the files and the server will not be operational for the time being.
No Data Corruption & Data Integrity in Web Hosting
We've tackled the issue of silent data corruption on all our web hosting servers by using the state-of-the-art 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 the 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 NVMe drives and regularly synchronized between them for redundancy. ZFS regularly examines the checksum of all files and in case any file is detected as corrupted, it is replaced instantly with a good copy from some other disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the other NVMes. ZFS requires plenty of physical memory in order to execute 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 information will be undamaged no matter what.
