The process of files being damaged as a consequence of some hardware or software failure is referred to as data corruption and this is among the main problems which hosting companies face because the larger a hard disk drive is and the more information is placed on it, the more likely it is for data to become corrupted. You will find different fail-safes, yet often the info becomes damaged silently, so neither the particular file system, nor the admins detect a thing. Consequently, a corrupted file will be handled as a regular one and if the hard disk drive is a part of a RAID, the file will be duplicated on all other drives. Theoretically, this is done for redundancy, but in practice the damage will be even worse. The moment some file gets corrupted, it will be partially or entirely unreadable, so a text file will not be readable, an image file will display a random combination of colors if it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most widely used server file systems have various checks, they are likely to fail to discover a problem early enough or require an extensive amount of time to check all the files and the web hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

We have resolved the issue of silent data corruption on our shared hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one in existence that checks all files immediately by employing a checksum - a digital identifier that is unique for every single 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 compares the checksum of all files and when any file is detected as damaged, it's replaced instantly 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 to execute the real-time checks and the advantage of our cloud hosting platform is that we employ multiple powerful servers working together. If you host your websites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't encounter any kind of silent data corruption issues whatsoever in case you purchase one of our semi-dedicated server packages as the ZFS file system that we take advantage of on our cloud hosting platform uses checksums 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 stored on a server. As we store all content on multiple drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the only file system out there that uses checksums, which makes it far superior to other file systems which are not able to detect silent data corruption and duplicate bad files across drives.
