The process of files being damaged because of some hardware or software failure is known as data corruption and this is one of the main problems that hosting companies face since the larger a hard drive is and the more info is kept on it, the more likely it is for data to get corrupted. You'll find various fail-safes, yet often the information gets damaged silently, so neither the particular file system, nor the admins see anything. As a result, a bad file will be treated as a regular one and if the HDD is a part of a RAID, that particular file will be duplicated on all other drives. Theoretically, this is for redundancy, but in practice the damage will be worse. Once some file gets corrupted, it will be partially or completely unreadable, so a text file will no longer be readable, an image file will display a random mix 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 often fail to identify some problem early enough or require an extensive period of time to check all of the files and the web server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the data uploaded in every shared hosting account which is created on our cloud platform because we employ the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption using a unique checksum for each and every file. We shall store your info on a large number of SSD drives which operate in a RAID, so the same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and if the checksum of any file is different from what it has to be, the file system replaces that file with a healthy version from a different drive within the RAID. There's no other file system which uses checksums, so it's easy for data to be silently corrupted and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you won't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you purchase one of our semi-dedicated server plans, you won't need to worry about silent data corruption because we use ZFS - a high level file system which keeps track of all files in real time. Every time you upload a file to your website 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 of the copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no threat for any part of your content at any moment. By comparison, all of the other file systems carry out checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy may be replicated on the remaining drives as well and you could lose crucial data. Since this isn't the case with ZFS, we are able to warrant the integrity of every single file you upload no matter what.
