The process of files getting corrupted owing to some hardware or software failure is known as data corruption and this is one of 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 be corrupted. You can find a couple of fail-safes, yet often the data is corrupted silently, so neither the particular file system, nor the admins detect anything. Consequently, a bad file will be treated as a standard one and if the hard disk is part of a RAID, the file will be duplicated on all other disk drives. Theoretically, this is done for redundancy, but in practice the damage will be even worse. When a given file gets corrupted, it will be partially or entirely unreadable, so a text file will no longer be readable, an image file will display a random mix of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your website content. Although the most well-known server file systems include various checks, they quite often fail to identify some problem early enough or require an extensive time period in order to check all of the files and the server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Web Hosting

We have tackled the problem of silent data corruption on all of our shared web hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is superior to other file systems since it is the only one out there that checks all of the files right away by using a checksum - a digital identifier that's unique for each file. When you upload content to your account, it will be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS regularly compares the checksum of all files and in case 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 bad file may remain or may be duplicated on the other SSDs. ZFS requires plenty of physical memory to execute 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 sites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not encounter any kind of silent data corruption issues should you buy one of our semi-dedicated server packages as the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to guarantee that all of the files are undamaged all the time. A checksum is a unique digital fingerprint which is given to each and every file saved on a server. Since 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 right away. In the event that 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 bad copy to be synchronized on the rest of the hard drives. ZFS is the only file system available on the market that uses checksums, which makes it far superior to other file systems that cannot identify silent data corruption and duplicate bad files across drives.
