The process of files getting corrupted because of some hardware or software failure is referred to as data corruption and this is among the main problems that hosting companies face because the larger a hard disk is and the more information is placed on it, the more likely it is for data to get corrupted. You can find several fail-safes, but often the data becomes corrupted silently, so neither the particular file system, nor the admins notice anything. As a result, a damaged file will be handled as a regular one and if the HDD is a part of a RAID, that particular file will be copied on all other drives. In principle, this is for redundancy, but in reality the damage will be worse. When a file gets corrupted, it will be partially or fully unreadable, so a text file will not be readable, an image file will present a random mix of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your site content. Although the most widespread server file systems feature various checks, they quite often fail to find a problem early enough or require a vast time period to be able to check all files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Hosting

The integrity of the data that you upload to your new hosting account will be ensured by the ZFS file system that we take advantage of on our cloud platform. The majority of web hosting suppliers, including our company, use multiple HDDs to keep content and considering that the drives work in a RAID, the same data is synchronized between the drives at all times. When a file on a drive is damaged for reasons unknown, yet, it is very likely that it will be duplicated on the other drives as alternative file systems do not have special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, so the damaged copy will be swapped with a good one from another disk drive. As this happens instantly, there is no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not encounter any silent data corruption issues whatsoever should you acquire one of our semi-dedicated server packages as the ZFS file system that we use 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 which is assigned to each and every file saved on a server. Because we store all content on a number of drives simultaneously, the same file has the same checksum on all of the 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 other hard disks. ZFS is the only file system out there that uses checksums, which makes it much more reliable than other file systems that are unable to detect silent data corruption and copy bad files across hard drives.
