The process of files getting corrupted owing to some hardware or software failure is known as data corruption and this is among the main problems which Internet hosting companies face as the larger a hard disk is and the more information is stored on it, the more likely it is for data to get corrupted. There're different fail-safes, yet often the information becomes damaged silently, so neither the file system, nor the admins notice a thing. As a result, a damaged file will be handled as a regular one and if the hard disk drive is a part of a RAID, that file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in reality the damage will be even worse. When a file gets damaged, it will be partially or entirely unreadable, therefore a text file will no longer 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, so you risk sacrificing your website content. Although the most widely used server file systems feature various checks, they quite often fail to identify a problem early enough or require a vast amount of time to check all of the files and the server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Web Hosting

We've resolved the issue of silent data corruption on all our shared web hosting servers by using the amazing Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one on the market that checks all the files in real time by using a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and regularly synced between them for redundancy. ZFS constantly compares the checksum of all files and in the event that any file is detected as damaged, it is replaced promptly with a good copy from some other disk. As this happens in real time, there's no risk that a damaged file may remain or may be duplicated on the other SSDs. ZFS requires plenty of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we take advantage of multiple very powerful servers working together. In case you host your Internet sites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you obtain one of our semi-dedicated server packages, you will not have to be concerned about silent data corruption because we use ZFS - an advanced file system which keeps track of all files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between multiple SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This is done immediately, so there will be no threat for any part of your content at any time. By comparison, alternative file systems execute checks after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a corrupted copy can be replicated on the remaining disks as well and you can lose critical info. As this is not the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
