The process of files being damaged as a consequence of some hardware or software failure is referred to as data corruption and this is among the main problems which hosting companies face because the larger a hard drive is and the more information is filed on it, the more likely it is for data to be corrupted. You'll find a couple of fail-safes, but often the data becomes damaged silently, so neither the particular file system, nor the admins notice anything. Because of this, a damaged file will be treated as a standard one and if the hard drive is part of a RAID, that file will be duplicated on all other drives. In principle, this is done for redundancy, but in reality the damage will get even worse. The moment a given file gets corrupted, it will be partly or fully unreadable, so a text file will not be readable, an image file will present a random combination of colors in case it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your website content. Although the most widespread 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 files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data that you upload to your new cloud web hosting account shall be guaranteed by the ZFS file system that we take advantage of on our cloud platform. The vast majority of web hosting suppliers, like our firm, use multiple hard disk drives to store content and since the drives work in a RAID, the same information is synchronized between the drives all the time. If a file on a drive is corrupted for some reason, however, it's likely that it will be duplicated on the other drives because other file systems do not include special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each and every file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, which means that the bad copy shall be replaced with a good one from another hard disk drive. Since this happens immediately, there's no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any risk of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created employ a powerful file system known as ZFS. Its key advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's 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 rest of the drives and the one it has saved. In the event that there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and because this happens right away, there's no chance that a damaged copy can remain on our servers or that it can be duplicated to the other drives in the RAID. None of the other file systems work with this kind of checks and furthermore, even during a file system check right after a sudden electrical power failure, none of them will identify silently corrupted files. In contrast, ZFS will not crash after a power loss and the constant checksum monitoring makes a time-consuming file system check unneeded.
