The process of files getting damaged owing to some hardware or software failure is known as data corruption and this is among the main problems which Internet hosting companies face because the larger a hard disk drive is and the more info is kept on it, the much more likely it is for data to become corrupted. You can find different fail-safes, still often the info gets damaged silently, so neither the file system, nor the admins notice a thing. Consequently, a bad file will be handled as a standard one and if the HDD is a part of a RAID, that file will be copied on all other disk drives. In theory, this is done for redundancy, but in practice the damage will get worse. Once some file gets corrupted, it will be partly or fully unreadable, which means that a text file will not be readable, an image file will show a random combination of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your website content. Although the most commonly used server file systems include various checks, they quite often fail to identify some problem early enough or require a vast amount of time in order to check all files and the web server will not be functional for the time being.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your Internet sites in a cloud hosting account from our firm, you will not have to worry about your data ever getting damaged. We can ensure that since our cloud hosting platform employs the leading-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. All data that you upload will be saved in a RAID i.e. simultaneously on multiple NVMes. All of the file systems synchronize the files between the different drives using this kind of a setup, but there is no real guarantee that a file will not be corrupted. This can happen at the time of the writing process on each drive and after that a bad copy can be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives instantly and if a corrupted file is identified, it's replaced with a good copy with the correct checksum from some other drive. In this way, your data will continue to be intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any chance of files getting damaged silently as the servers where your semi-dedicated server account will be created work with a powerful file system named ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we keep all content on multiple NVMe drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. When there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and considering that this happens in real time, there's no chance that a damaged copy can remain on our website hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems work with this type of checks and what is more, even during a file system check right after an unexpected power failure, none of them will identify silently corrupted files. In contrast, ZFS doesn't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unnecessary.
