The process of files getting damaged caused by some hardware or software failure is known as data corruption and this is among the main problems that web hosting companies face because the larger a hard disk drive is and the more data is placed on it, the more likely it is for data to be corrupted. You'll find different fail-safes, still often the information gets corrupted silently, so neither the particular file system, nor the admins notice a thing. Consequently, a damaged file will be handled as a good one and if the HDD is part of a RAID, that particular file will be duplicated on all other disk drives. In theory, this is done for redundancy, but in practice the damage will be even worse. Once some file gets damaged, it will be partly or completely unreadable, therefore a text file will not 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 sacrificing your website content. Although the most widespread server file systems feature various checks, they frequently fail to identify some problem early enough or require a vast amount of time to check all files and the web 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 every single web hosting
account that is created on our cloud platform because we work with the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption via a unique checksum for each file. We will store your information on a large number of SSD drives which operate in a RAID, so the same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all the drives in real time and if the checksum of any file is different from what it needs to be, the file system replaces that file with an undamaged version from some other drive from 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 replicated on all drives over time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not experience any silent data corruption issues whatsoever if you obtain one of our semi-dedicated server
packages since the ZFS file system that we employ on our cloud hosting platform uses checksums in order to ensure that all of your files are intact all the time. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. As we store all content on multiple drives at the same time, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. When it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any probability of the bad copy to be synchronized on the rest of the hard disks. ZFS is the sole file system you can get which uses checksums, which makes it much more reliable than other file systems that are unable to identify silent data corruption and duplicate bad files across hard drives.
