The process of files getting corrupted resulting from some hardware or software failure is called data corruption and this is among the main problems which web hosting companies face because the larger a hard disk drive is and the more info is stored on it, the more likely it is for data to be corrupted. There're several fail-safes, but often the info gets corrupted silently, so neither the file system, nor the admins detect anything. Because of this, a corrupted file will be handled as a regular one and if the hard disk drive is a part of a RAID, that file will be copied on all other drives. In theory, this is done for redundancy, but in practice the damage will be worse. When a given file gets damaged, it will be partially or entirely unreadable, so a text file will no longer be readable, an image file will show a random combination of colors if it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most popular server file systems include various checks, they quite often fail to identify some problem early enough or require a vast amount of time in order to check all of the files and the server will not be operational in the meantime.

No Data Corruption & Data Integrity in Web Hosting

We warrant the integrity of the information uploaded in each web hosting account that is generated on our cloud platform as we use the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption using a unique checksum for each file. We'll store your info on a number of NVMe drives which work in a RAID, so identical files will be present on several places at once. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file is different from what it has to be, the file system replaces that file with a healthy copy from a different drive inside the RAID. There's no other file system which uses checksums, so it's possible for data to be silently corrupted and the bad file to be duplicated on all drives over time, but since this can never happen on a server running ZFS, you will not have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any probability of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created employ a powerful file system called ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. As 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 is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and considering that this happens instantly, there is no chance that a damaged copy can remain on our servers or that it can be copied to the other hard drives in the RAID. None of the other file systems include this kind of checks and what is more, even during a file system check after an unexpected power loss, none of them will discover silently corrupted files. In contrast, ZFS does not crash after a power loss and the constant checksum monitoring makes a time-consuming file system check obsolete.
