The process of files being corrupted as a consequence of some hardware or software failure is called data corruption and this is one of the main problems which hosting companies face since the larger a hard disk drive is and the more data is filed on it, the much more likely it is for data to get corrupted. You will find several fail-safes, but often the information gets corrupted silently, so neither the file system, nor the administrators notice a thing. As a result, a damaged file will be treated as a standard one and if the hard disk is part of a RAID, that particular file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will be even worse. When a file gets damaged, it will be partly or fully unreadable, which means that a text file will no longer be readable, an image file will present a random combination of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your website content. Although the most widely used server file systems feature various checks, they quite often fail to identify some problem early enough or require a vast amount of time to be able to check all the files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Website Hosting

The integrity of the data that you upload to your new cloud website hosting account will be guaranteed by the ZFS file system that we make use of on our cloud platform. Most internet hosting providers, like our firm, use multiple hard disk drives to keep content and considering that the drives work in a RAID, identical data is synchronized between the drives all of the time. If a file on a drive is corrupted for whatever reason, yet, it is likely that it will be reproduced on the other drives as other file systems don't feature special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every single file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy will be substituted with a good one from another hard disk drive. Due to the fact that this happens in real time, there is no possibility for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any possibility of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created work with a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we keep all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. In case there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens right away, there's no chance that a corrupted copy can remain on our servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems work with such checks and what's more, even during a file system check right after an unexpected power loss, none of them can detect silently corrupted files. In contrast, ZFS doesn't crash after a power loss and the continual checksum monitoring makes a lenghty file system check unneeded.
