The process of files being damaged caused by some hardware or software failure is known as data corruption and this is one of the main problems that Internet hosting companies face as the larger a hard drive is and the more information is placed on it, the much more likely it is for data to get corrupted. You'll find a couple of fail-safes, still often the info is damaged silently, so neither the particular file system, nor the admins see a thing. Because of this, a bad file will be treated as a good one and if the HDD is part of a RAID, that particular file will be duplicated on all other disk drives. In principle, this is for redundancy, but in reality the damage will get worse. Once some file gets corrupted, it will be partly or completely unreadable, which means that a text file will not be readable, an image file will present a random combination 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 frequently fail to identify some problem early enough or require a long period of time to check all files and the hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Website Hosting
The integrity of the data which you upload to your new website hosting account shall be ensured by the ZFS file system which we make use of on our cloud platform. The majority of hosting suppliers, including our firm, use multiple hard disk drives to store content and because the drives work in a RAID, exactly the same data is synchronized between the drives all the time. If a file on a drive gets damaged for reasons unknown, yet, it's likely that it will be duplicated on the other drives since other file systems do not include special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each and every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the bad copy shall be swapped with a good one from a different drive. Because this happens immediately, there is no risk for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't need to deal with any kind of silent data corruption issues in case you get one of our semi-dedicated hosting solutions as the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all of the files are intact all the time. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. As we store all content on multiple drives simultaneously, 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 has to be, it replaces that file with a healthy copy without delay, avoiding any possibility of the corrupted copy to be synchronized on the other hard disks. ZFS is the only file system you can find which uses checksums, which makes it far superior to other file systems that are unable to detect silent data corruption and duplicate bad files across drives.
