The process of files getting damaged resulting from some hardware or software failure is called data corruption and this is one of the main problems which web hosting companies face since the larger a hard drive is and the more data is filed on it, the much more likely it is for data to be corrupted. There're various fail-safes, but often the data becomes corrupted silently, so neither the particular file system, nor the administrators see a thing. Consequently, a damaged file will be treated as a standard one and if the hard drive is part of a RAID, that particular file will be duplicated on all other drives. Theoretically, this is done for redundancy, but in reality the damage will be worse. The moment a file gets corrupted, it will be partly or entirely unreadable, which means that a text file will not be readable, an image file will show a random combination of colors in case it opens at all and an archive will be impossible to unpack, so you risk losing your site content. Although the most popular server file systems include various checks, they frequently fail to find some problem early enough or require an extensive time period in order to check all the files and the server will not be operational for the time being.

No Data Corruption & Data Integrity in Website Hosting

We've tackled the problem of silent data corruption on our website hosting servers by using the amazing Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one out there which checks all the files in real time 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 constantly analyzes the checksum of all files and in the event that any file is detected as corrupted, it's replaced immediately with a good copy from another disk. As this happens in real time, there is no risk that a damaged file may remain or may be copied on the remaining NVMes. ZFS requires plenty of physical memory to carry out the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple 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

You will not encounter any silent data corruption issues should you acquire one of our semi-dedicated server solutions as the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to guarantee that all the files are intact all the time. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. Since we store all content on multiple drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any possibility of the corrupted copy to be synchronized on the remaining hard drives. ZFS is the only file system you will find that uses checksums, which makes it much more dependable than other file systems that cannot identify silent data corruption and duplicate bad files across hard drives.
