The process of files getting damaged as a consequence of some hardware or software failure is known as data corruption and this is among the main problems that hosting companies face as the larger a hard disk is and the more data is placed on it, the more likely it is for data to get corrupted. You'll find several fail-safes, but often the data is damaged silently, so neither the particular file system, nor the administrators detect a thing. Because of this, a bad file will be handled as a standard one and if the hard disk drive is part of a RAID, that file will be copied on all other disk drives. Theoretically, this is done for redundancy, but in practice the damage will get even worse. Once some file gets corrupted, it will be partially or fully unreadable, which means that a text file will not be readable, an image file will show a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most widely used server file systems include various checks, they quite often fail to detect some problem early enough or require a long period of time in order to check all files and the hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Web Hosting

We have tackled the problem of silent data corruption on our shared web hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one on the market that checks all files instantly by employing a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it'll be stored on several NVMe drives and constantly synchronized between them for redundancy. ZFS regularly compares the checksum of all files and when any file is detected as damaged, it is replaced quickly 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 copied on the rest of the NVMes. ZFS requires a lot of physical memory in order to execute the real-time checks and the benefit of our cloud hosting platform is that we employ multiple powerful servers working together. If you host your Internet sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't need to deal with any silent data corruption issues whatsoever should you purchase one of our semi-dedicated server packages because the ZFS file system that we work with on our cloud hosting platform uses checksums in order to ensure that all the files are intact at all times. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. If 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 right away, avoiding any probability of the damaged copy to be synchronized on the other drives. ZFS is the only file system on the market that uses checksums, which makes it far superior to other file systems which cannot identify silent data corruption and duplicate bad files across hard drives.
