The process of files getting damaged resulting from some hardware or software failure is referred to as data corruption and this is among the main problems that hosting companies face since the larger a hard drive is and the more info is filed on it, the much more likely it is for data to get corrupted. There're a couple of fail-safes, but often the data is corrupted silently, so neither the file system, nor the admins detect a thing. Because of this, a damaged file will be handled as a standard one and if the hard drive is a part of a RAID, that particular file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in reality the damage will get even worse. Once some file gets corrupted, it will be partly or completely 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, and you risk sacrificing your content. Although the most popular server file systems include various checks, they quite often fail to detect a problem early enough or require a long period of time in order to check all of the files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Web Hosting

We have dealt with the problem of silent data corruption on all of our shared web hosting servers by using the leading-edge Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one out there that checks all files instantly by employing a checksum - a digital identifier that is unique for each file. When you upload content to your account, it will be stored on several NVMe drives and frequently synced between them for redundancy. ZFS regularly compares the checksum of all files and in the event that any file is detected as damaged, it's replaced promptly with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the other NVMes. ZFS requires plenty of physical memory to execute the real-time checks and the benefit of our cloud hosting platform is that we use multiple very powerful servers working together. If you host your websites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not experience any kind of silent data corruption issues whatsoever in case you obtain one of our semi-dedicated hosting packages since the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all of your files are intact at all times. A checksum is a unique digital fingerprint which is assigned to each and every file stored on a server. Since we store all content on multiple drives at the same time, 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. When 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 chance of the bad copy to be synchronized on the rest of the drives. ZFS is the only file system you can get which uses checksums, which makes it much more dependable than other file systems which are unable to detect silent data corruption and copy bad files across hard drives.
