The process of files being damaged due to some hardware or software failure is referred to as data corruption and this is among the main problems that Internet hosting companies face because the larger a hard disk is and the more info is placed on it, the more likely it is for data to become corrupted. You will find different fail-safes, but often the data gets corrupted silently, so neither the file system, nor the admins notice anything. As a result, a damaged file will be handled as a good one and if the hard drive is part of a RAID, the file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will be worse. When a file gets corrupted, it will be partly or entirely unreadable, so a text file will no longer be readable, an image file will present a random blend of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your website content. Although the most commonly used server file systems feature various checks, they quite often fail to identify a problem early enough or require a vast period of time to check all the files and the server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Website Hosting

We guarantee the integrity of the info uploaded in every shared website hosting account that is created 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 thanks to a unique checksum for each file. We'll store your info on multiple SSD drives which work in a RAID, so the same files will be available on several places concurrently. ZFS checks the digital fingerprint of all the files on all of the drives in real time and if the checksum of any file differs from what it has to be, the file system replaces that file with an undamaged copy from another drive from the RAID. No other file system uses checksums, so it is easy for data to get silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any possibility of files getting damaged silently due to the fact that 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 which is checked in real time. As we keep all content on a number of SSD 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. In case there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because this happens right away, there's no chance that a damaged copy could remain on our hosting servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems include this type of checks and what's more, even during a file system check following an unexpected power loss, none of them can discover silently corrupted files. In comparison, ZFS will not crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unneeded.
