The process of files getting corrupted caused by some hardware or software failure is known as data corruption and this is one of the main problems which hosting companies face since the larger a hard drive is and the more data is filed on it, the more likely it is for data to be corrupted. There are various fail-safes, still often the data is damaged silently, so neither the particular file system, nor the admins see a thing. Because of this, a corrupted file will be handled as a standard one and if the hard disk drive is a part of a RAID, that file will be duplicated on all other disk drives. In theory, this is for redundancy, but in reality the damage will be worse. When a given file gets corrupted, it will be partially or fully unreadable, therefore a text file will not be readable, an image file will show a random blend of colors in case it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your content. Although the most frequently used server file systems feature various checks, they are likely to fail to detect a problem early enough or require a long amount of time to be able to check all of the files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Cloud Website Hosting

We've resolved the issue of silent data corruption on all of our cloud website hosting servers by using the cutting-edge 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 of the files immediately by using a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it will be stored on several NVMe drives and constantly synced between them for redundancy. ZFS constantly compares 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 damaged file may remain or may be duplicated on the rest of the NVMes. ZFS requires plenty of physical memory to execute the real-time checks and the benefit of our cloud hosting platform is that we work with multiple very powerful servers working together. If you host your sites with us, your info will be undamaged no matter what.
