The process of files being damaged resulting from some hardware or software failure is called data corruption and this is one of the main problems which Internet hosting companies face as the larger a hard disk is and the more info is filed on it, the much more likely it is for data to be corrupted. There are different fail-safes, still often the information becomes damaged silently, so neither the file system, nor the admins detect a thing. As a result, a damaged file will be handled as a regular one and if the hard disk is part of a RAID, that particular file will be copied on all other drives. In theory, this is done for redundancy, but in reality the damage will get worse. The moment a given file gets damaged, it will be partly or entirely unreadable, so a text file will not be readable, an image file will display a random combination of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most widespread server file systems feature various checks, they frequently fail to detect a problem early enough or require a vast amount of time to be able to check all files and the web hosting server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Website Hosting

We have tackled the problem of silent data corruption on our shared website hosting servers by using the amazing Z file system, or ZFS. The latter is superior to other file systems since it is the only one in existence which checks all files in real time by employing a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and continually synced between them for redundancy. ZFS constantly compares the checksum of all files and when any file is detected as corrupted, it's replaced promptly with a good copy from some other disk. As this happens in real time, there is no risk that a damaged file may remain or may be duplicated on the remaining SSDs. ZFS requires lots of physical memory to carry out the real-time checks and the advantage of our cloud web hosting platform is that we work with multiple powerful servers working together. If you host your websites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you go for one of our semi-dedicated server plans, you will not need to worry about silent file corruption because we use ZFS - an advanced file system which keeps track of all the files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between a couple of SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This happens right away, so there will be no threat for any part of your content at any moment. In comparison, alternative file systems execute checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you could lose important data. As this is not the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
