The process of files being corrupted as a result of some hardware or software failure is called data corruption and this is among the main problems which hosting companies face as the larger a hard drive is and the more info is stored on it, the much more likely it is for data to get corrupted. There're a couple of fail-safes, still often the information gets damaged silently, so neither the particular file system, nor the admins notice a thing. Because of this, a corrupted file will be treated as a regular one and if the hard drive is a part of a RAID, that file will be duplicated on all other drives. In theory, this is for redundancy, but in practice the damage will be even worse. The moment a given file gets damaged, it will be partially or fully unreadable, so a text file will no longer be readable, an image file will show a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your website content. Although the most commonly used server file systems include various checks, they quite often fail to find a problem early enough or require a vast amount of time to be able to check all of the files and the server will not be functional for the time being.

No Data Corruption & Data Integrity in Website Hosting

We have dealt with the issue of silent data corruption on our website hosting servers by using the hi-tech Z file system, or ZFS. The latter is superior to other file systems because it is the only one on the market which checks all files right away by using a checksum - a digital identifier that's unique for each file. When you upload content to your account, it'll be stored on several SSD drives and continually synced between them for redundancy. ZFS regularly analyzes the checksum of all files and in the event that any file is detected as corrupted, it is replaced quickly with a good copy from another disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the other SSDs. ZFS needs a lot of physical memory to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple very powerful servers working together. If you host your sites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you go for one of our semi-dedicated hosting solutions, you won't need to be concerned about silent data corruption since we use ZFS - an advanced file system that monitors all the files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a number of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no risk for any part of your content at any time. In comparison, all of the other file systems perform checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a bad copy can be replicated on the remaining disks as well and you may lose critical data. Because this isn't the case with ZFS, we are able to guarantee the integrity of each and every file you upload no matter what.
