The process of files getting corrupted resulting from some hardware or software failure is called data corruption and this is one of the main problems that Internet hosting companies face because the larger a hard drive is and the more info is stored on it, the much more likely it is for data to become corrupted. You will find various fail-safes, yet often the data gets damaged silently, so neither the particular file system, nor the administrators notice a thing. Thus, a corrupted file will be handled as a standard one and if the hard drive is a part of a RAID, the file will be copied on all other drives. In theory, this is done for redundancy, but in practice the damage will be even worse. When a given file gets damaged, it will be partially or entirely unreadable, therefore a text file will not be readable, an image file will present a random combination of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your site content. Although the most frequently used server file systems include various checks, they quite often fail to identify a problem early enough or require a long amount of time in order to check all of the files and the hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the data uploaded in any shared hosting account which is made on our cloud platform since we work with the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption thanks to a unique checksum for each file. We shall store your information on multiple NVMe drives which function in a RAID, so the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all of the 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 swaps that file with a healthy version from another drive inside the RAID. There's no other file system which uses checksums, so it's possible for data to become silently corrupted and the bad file to be reproduced on all drives with time, but since this can never happen on a server using ZFS, you will not have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any possibility of files getting corrupted silently as the servers where your semi-dedicated server account will be created use a powerful file system known as ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. As we keep all content on a number of 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. If there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since this happens instantly, there is no chance that a damaged copy could remain on our hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems employ this type of checks and what's more, even during a file system check after a sudden electrical power failure, none of them will discover silently corrupted files. In comparison, ZFS does not crash after a power failure and the regular checksum monitoring makes a lenghty file system check unneeded.
