The process of files being corrupted caused by some hardware or software failure is referred to as data corruption and this is one of the main problems that hosting companies face because the larger a hard drive is and the more info is placed on it, the much more likely it is for data to become corrupted. You will find a couple of fail-safes, still often the data becomes damaged silently, so neither the particular file system, nor the admins notice a thing. As a result, a bad file will be treated as a standard one and if the hard disk is a part of a RAID, that file will be copied on all other disk drives. Theoretically, this is done for redundancy, but in reality the damage will be worse. Once some file gets corrupted, it will be partly or entirely unreadable, which means that a text file will no longer be readable, an image file will display a random blend 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 have various checks, they frequently fail to find some problem early enough or require an extensive amount of time to be able to check all of the files and the web hosting server will not be functional for the time being.

No Data Corruption & Data Integrity in Hosting

If you host your websites in a hosting account with our firm, you don't need to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform employs the reliable ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. All data that you upload will be kept in a RAID i.e. simultaneously on a large number of SSD drives. Many file systems synchronize the files between the separate drives using this type of a setup, but there's no real guarantee that a file will not be corrupted. This may occur at the time of the writing process on each drive and afterwards a bad copy can be copied on the rest of the drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all drives right away and if a corrupted file is found, it's replaced with a good copy with the correct checksum from another drive. By doing this, your information will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any probability of files getting damaged silently as the servers where your semi-dedicated server account will be created take advantage of a powerful file system called ZFS. Its main advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. As we store all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has stored. In case there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since it happens in real time, there is no chance that a damaged copy could remain on our web hosting servers or that it can be duplicated to the other drives in the RAID. None of the other file systems employ this kind of checks and what is more, even during a file system check after an unexpected power loss, none of them can identify silently corrupted files. In contrast, ZFS doesn't crash after a power loss and the regular checksum monitoring makes a lenghty file system check unnecessary.
