The process of files getting damaged as a consequence of some hardware or software failure is called data corruption and this is one of the main problems that hosting companies face since the larger a hard disk is and the more information is stored on it, the much more likely it is for data to become corrupted. There're different fail-safes, but often the info is corrupted silently, so neither the file system, nor the administrators detect a thing. Consequently, a damaged file will be handled as a standard one and if the hard disk drive is part of a RAID, that file will be copied on all other disk drives. In theory, this is done for redundancy, but in reality the damage will get worse. The moment a file gets corrupted, it will be partially or fully unreadable, which means that a text file will not be readable, an image file will present a random blend of colors in case it opens at all and an archive will be impossible to unpack, so you risk losing your site content. Although the most well-known server file systems have various checks, they frequently fail to find a problem early enough or require a vast period of time to be able to check all files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Web Hosting

In case you host your sites in a web hosting account with our firm, you won't have to worry about your data ever getting damaged. We can ensure that because our cloud hosting platform works with the revolutionary ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All of the data that you upload will be kept in a RAID i.e. simultaneously on many SSD drives. All of the file systems synchronize the files between the different drives with this kind of a setup, but there is no real guarantee that a file will not get corrupted. This can occur at the time of the writing process on each drive and then a bad copy may be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all the drives instantly and in the event that a corrupted file is discovered, it's substituted with a good copy with the correct checksum from some other drive. By doing this, your info will continue to be undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not experience any kind of silent data corruption issues whatsoever should you obtain one of our semi-dedicated server plans due to the fact that the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all the files are undamaged all of the time. A checksum is a unique digital fingerprint that is allotted to each and every file stored on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any probability of the bad copy to be synchronized on the rest of the hard drives. ZFS is the only file system available on the market which uses checksums, which makes it much more reliable than other file systems which are unable to identify silent data corruption and copy bad files across drives.
