No Data Corruption & Data Integrity
Find out what No Data Corruption & Data Integrity is and how it could be beneficial for the files within your website hosting account.
The process of files getting corrupted as a consequence of some hardware or software failure is referred to as data corruption and this is among the main problems which web hosting companies face since the larger a hard drive is and the more data is kept on it, the much more likely it is for data to be corrupted. There are a couple of fail-safes, yet often the info gets corrupted silently, so neither the particular file system, nor the administrators notice anything. As a result, a corrupted file will be treated as a regular one and if the hard disk is part of a RAID, that particular file will be duplicated on all other drives. In principle, this is for redundancy, but in reality the damage will be even worse. The moment a file gets damaged, it will be partially or entirely unreadable, so a text file will no longer be readable, an image file will display a random combination of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your content. Although the most widespread server file systems have various checks, they quite often fail to find some problem early enough or require an extensive period of time in order to check all of the files and the web hosting server will not be functional for the time being.

No Data Corruption & Data Integrity in Cloud Hosting
We've resolved the problem 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 better than other file systems since it is the only one on the market 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 regularly synced between them for redundancy. ZFS regularly analyzes the checksum of all files and when any file is detected as corrupted, it is 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 other NVMes. ZFS requires a lot of physical memory in order to carry out the real-time checks and the benefit of our cloud website hosting platform is that we employ multiple powerful servers working together. In case you host your sites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you acquire one of our
semi-dedicated server plans, you will not have to worry about silent data corruption as we use ZFS - a high level file system that keeps track of all files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a number of NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done right away, so there will be no danger for any part of your content at any time. In contrast, other file systems carry out checks only after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a bad copy may be replicated on the other disks as well and you may lose crucial info. Because this isn't the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
