The process of files being damaged resulting from some hardware or software failure is known as data corruption and this is among the main problems which hosting companies face as the larger a hard disk drive is and the more information is kept on it, the much more likely it is for data to become corrupted. You'll find different fail-safes, but often the information becomes damaged silently, so neither the file system, nor the administrators detect a thing. As a result, a bad file will be handled as a regular one and if the hard disk is part of a RAID, that particular file will be duplicated on all other drives. Theoretically, this is done for redundancy, but in reality the damage will get worse. When a file gets corrupted, it will be partially or fully unreadable, which means that a text file will no longer be readable, an image file will show a random mix of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your content. Although the most frequently used server file systems include various checks, they are likely to fail to detect some problem early enough or require an extensive time period in order to check all of the files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Website Hosting
We warrant the integrity of the data uploaded in any cloud website hosting account that is created on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption through a unique checksum for each file. We will store your data on multiple SSD drives which operate in a RAID, so the exact same files will exist on several places at once. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from another drive inside the RAID. There's no other file system which uses checksums, so it's possible for data to be silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any risk of files getting damaged silently due to the fact that the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. As we save all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. In case there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because it happens instantly, there's no chance that a corrupted copy can remain on our website hosting servers or that it can be copied to the other hard disks in the RAID. None of the other file systems work with this kind of checks and in addition, even during a file system check right after an unexpected power failure, none of them will find silently corrupted files. In contrast, ZFS will not crash after an electrical power failure and the continual checksum monitoring makes a time-consuming file system check obsolete.
