The process of files being corrupted as a consequence of some hardware or software failure is known as data corruption and this is one of the main problems which web hosting companies face since the larger a hard disk is and the more information is filed on it, the more likely it is for data to be corrupted. You can find a couple of fail-safes, still often the information is corrupted silently, so neither the file system, nor the admins detect a thing. Thus, a corrupted file will be handled as a regular one and if the hard drive is part of a RAID, that file will be duplicated on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will be worse. Once a given file gets corrupted, it will be partly or completely unreadable, so a text file will no longer be readable, an image file will show a random mix of colors if it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most well-known server file systems feature various checks, they frequently fail to discover some problem early enough or require a vast amount of time to be able to check all files and the web hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the data uploaded in every shared hosting account that is made on our cloud platform as we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption through a unique checksum for every single file. We shall store your information on a large number of NVMe drives that work in a RAID, so the same files will be available on several places at the same time. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file differs from what it has to be, the file system replaces that file with an undamaged version from a different drive within 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 won't have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any probability of files getting corrupted silently as the servers where your semi-dedicated server account will be created employ a powerful file system named ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. Since we keep all content on a number of NVMe drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. 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 in real time, there's no chance that a damaged copy could remain on our website hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems include such checks and what's more, even during a file system check right after a sudden power failure, none of them can discover silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
