The process of files getting corrupted as a result of some hardware or software failure is called data corruption and this is among the main problems which hosting companies face as the larger a hard drive is and the more data is placed on it, the more likely it is for data to become corrupted. You will find several fail-safes, yet often the data is corrupted silently, so neither the particular file system, nor the administrators detect a thing. Thus, a bad file will be treated as a regular one and if the hard drive 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 even worse. Once a file gets damaged, it will be partially or completely unreadable, which means that a text file will not be readable, an image file will show a random blend of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your website content. Although the most popular server file systems feature various checks, they often fail to detect a problem early enough or require an extensive amount of time to be able to check all files and the web hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Web Hosting

We guarantee the integrity of the info uploaded in each web hosting account which is generated on our cloud platform since we work with the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption thanks to a unique checksum for every single file. We'll store your information on multiple NVMe drives which operate in a RAID, so exactly the same files will exist on several places at the same time. ZFS checks the digital fingerprint of all of the files on all drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with a healthy version from another drive within the RAID. There's no other file system that uses checksums, so it is possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since this can never happen on a server running ZFS, you do not have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created employ a powerful file system called ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. Since we save all content on multiple NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has saved. When there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and since this happens instantly, there's no chance that a corrupted copy can remain on our servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems use such checks and furthermore, even during a file system check after a sudden blackout, none of them can find silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check obsolete.
