The process of files being damaged because of some hardware or software failure is called data corruption and this is among the main problems which Internet hosting companies face as the larger a hard drive is and the more information is kept on it, the more likely it is for data to become corrupted. There're various fail-safes, still often the information gets damaged silently, so neither the particular file system, nor the admins notice anything. Consequently, a bad file will be handled as a good one and if the hard drive is a part of a RAID, the file will be duplicated on all other drives. In theory, this is done for redundancy, but in reality the damage will get worse. Once a file gets damaged, it will be partially or fully unreadable, so a text file will no longer be readable, an image file will present a random combination of colors in case 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 often fail to identify a problem early enough or require a vast period of time in order to check all of the files and the web hosting server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Website Hosting

We have dealt with the problem of silent data corruption on our shared website hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is better than other file systems since it is the only one on the market that checks all the 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 frequently synced between them for redundancy. ZFS regularly analyzes the checksum of all files and when any file is detected as damaged, it's replaced promptly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be duplicated on the remaining NVMes. ZFS requires plenty of physical memory in order to carry out the real-time checks and the benefit of our cloud web hosting platform is that we take advantage of multiple very powerful servers working together. In case you host your Internet sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not need to deal with any kind of silent data corruption issues in case you obtain one of our semi-dedicated hosting plans since the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all the files are intact at all times. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. Because we store all content on a number of drives at the same time, the same file uses the same checksum on all the 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 right away, avoiding any possibility of the corrupted copy to be synchronized on the remaining hard disks. ZFS is the only file system out there that 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.
