The process of files getting damaged owing to some hardware or software failure is known as data corruption and this is one of the main problems that web hosting companies face as the larger a hard disk is and the more info is placed on it, the more likely it is for data to be corrupted. There are various fail-safes, but often the info becomes corrupted silently, so neither the file system, nor the admins detect anything. As a result, a corrupted file will be handled as a regular one and if the hard disk drive is part of a RAID, the file will be duplicated on all other disk drives. In theory, this is for redundancy, but in practice the damage will be even worse. When a file gets corrupted, it will be partly or fully unreadable, so a text file will not 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, and you risk losing your website content. Although the most commonly used server file systems feature various checks, they quite often fail to detect some problem early enough or require an extensive time period to check all the files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Website Hosting

We warrant the integrity of the information uploaded in each and every shared website hosting account that is created on our cloud platform because we work with the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption through a unique checksum for every single file. We shall store your info on multiple SSD drives that operate in a RAID, so identical files will exist on several places at the same time. ZFS checks the digital fingerprint of all files on all of the drives in real time and in the event that the checksum of any file differs from what it has to be, the file system replaces that file with a healthy version from another drive from the RAID. There's no other file system that uses checksums, so it is easy for data to become silently damaged and the bad file to be duplicated on all drives with time, but since that can never happen on a server running ZFS, you will not have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any risk of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. Since we store all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. If there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that this happens instantly, there is no chance that a corrupted copy could remain on our servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems include this kind of checks and in addition, even during a file system check after an unexpected power failure, none of them can find silently corrupted files. In comparison, ZFS doesn't crash after a power failure and the regular checksum monitoring makes a time-consuming file system check unneeded.
