The process of files getting damaged caused by some hardware or software failure is called data corruption and this is one of the main problems which Internet hosting companies face as the larger a hard drive is and the more info is stored on it, the much more likely it is for data to get corrupted. You can find different fail-safes, yet often the information gets damaged silently, so neither the particular file system, nor the administrators see anything. Consequently, a damaged file will be handled as a standard one and if the hard drive is part of a RAID, that file will be copied on all other drives. In principle, this is done for redundancy, but in practice the damage will get even worse. When a given file gets corrupted, it will be partly or completely unreadable, so a text file will not be readable, an image file will display a random mix 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 frequently used server file systems have various checks, they often fail to find some problem early enough or require an extensive amount of time in order to check all files and the server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Web Hosting

If you host your websites in a shared web hosting account with our company, you will not need to worry about any of your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform uses the revolutionary ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. Any information that you upload will be saved in a RAID i.e. simultaneously on multiple SSD drives. All the file systems synchronize the files between the different drives with this type of a setup, but there's no real warranty that a file will not get corrupted. This can occur throughout the writing process on any drive and after that a damaged copy can be copied on the rest of the drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all the drives in real time and in the event that a corrupted file is discovered, it is replaced with a good copy with the correct checksum from some other drive. This way, your information will remain undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any probability of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its main advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. Since we store all content on a number of SSD 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 is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and since it happens instantly, there is no chance that a corrupted copy could remain on our web hosting servers or that it could be copied to the other drives in the RAID. None of the other file systems employ this type of checks and in addition, even during a file system check following an unexpected power loss, none of them can discover silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check unnecessary.
