The process of files getting damaged as a result of some hardware or software failure is referred to as data corruption and this is among the main problems that Internet hosting companies face as the larger a hard drive is and the more information is stored on it, the more likely it is for data to become corrupted. There're different fail-safes, but often the info becomes corrupted silently, so neither the particular file system, nor the admins notice a thing. Because of this, a bad file will be handled as a good one and if the hard drive is a part of a RAID, that file will be duplicated on all other drives. In principle, this is for redundancy, but in practice the damage will get worse. Once a file gets damaged, it will be partly or fully unreadable, which means that 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 will be impossible to unpack, and you risk sacrificing your content. Although the most commonly used server file systems include various checks, they often fail to discover some problem early enough or require a long period of time in order to check all files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Web Hosting

We guarantee the integrity of the data uploaded in every shared web hosting account which is made on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption through a unique checksum for each file. We will store your information on multiple SSD drives that work in a RAID, so the exact same files will be present on several places concurrently. ZFS checks the digital fingerprint of all of the files on all drives in real time and in the event that the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged version from some other drive inside the RAID. No other file system uses checksums, so it is easy for data to become silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server using ZFS, you won't have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you buy one of our semi-dedicated server solutions, you will not have to be concerned about silent data corruption because we use ZFS - a high level file system that monitors all of the files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between multiple 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 a different drive. This happens instantly, so there will be no threat for any part of your content at any time. In comparison, all of the other file systems carry out checks only after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a bad copy may be replicated on the other drives as well and you could lose precious data. Since this isn't the case with ZFS, we are able to guarantee the integrity of each and every file you upload no matter what.
