The process of files being damaged caused by some hardware or software failure is known as data corruption and this is among the main problems that hosting companies face as the larger a hard drive is and the more data is filed on it, the more likely it is for data to become corrupted. You will find different fail-safes, still often the information becomes damaged silently, so neither the file system, nor the admins detect a thing. As a result, a corrupted file will be handled as a good one and if the hard disk drive is a part of a RAID, that particular file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in practice the damage will get even worse. When some file gets corrupted, it will be partially or fully unreadable, so a text file will not be readable, an image file will present a random combination of colors in case it opens at all and an archive will be impossible to unpack, so you risk losing your website content. Although the most frequently used server file systems include various checks, they frequently fail to identify some problem early enough or require an extensive amount of time in order to check all files and the server will not be operational for the time being.
No Data Corruption & Data Integrity in Web Hosting
We warrant the integrity of the information uploaded in every web hosting account that is generated on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We shall store your info on multiple SSD drives that work in a RAID, so the very same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file differs from what it should be, the file system replaces that file with a healthy version from a different drive inside the RAID. No other file system uses checksums, so it's possible for data to get silently corrupted and the bad file to be duplicated on all drives over time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any possibility of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created employ a powerful file system known as ZFS. Its main advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. As we keep all content on a number of 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 saved. In case there is a mismatch, the bad 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 could remain on our web hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems include this kind of checks and what is more, even during a file system check following a sudden electrical power failure, none of them will discover silently corrupted files. In comparison, ZFS doesn't crash after a power failure and the regular checksum monitoring makes a lenghty file system check obsolete.
