The process of files being corrupted due to some hardware or software failure is known as data corruption and this is among the main problems which web hosting companies face since the larger a hard disk drive is and the more information is filed on it, the more likely it is for data to get corrupted. There're various fail-safes, but often the data becomes damaged silently, so neither the particular file system, nor the administrators see a thing. Because of this, a bad file will be treated as a good one and if the hard drive is a part of a RAID, that file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will get even worse. The moment a given file gets corrupted, it will be partly or completely unreadable, which means that a text file will not be readable, an image file will show a random blend of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your website content. Although the most popular server file systems include various checks, they often fail to detect some problem early enough or require an extensive period of time to be able to check all the files and the web server will not be functional for the time being.

No Data Corruption & Data Integrity in Cloud Web Hosting

We warrant the integrity of the info uploaded in each and every cloud web hosting account that is made on our cloud platform since we employ the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption through a unique checksum for each file. We shall store your info on a large number of SSD drives that work in a RAID, so the same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in case the checksum of any file differs from what it has to be, the file system replaces that file with a healthy copy from some other drive in the RAID. There's no other file system which uses checksums, so it's possible for data to be silently damaged and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you won't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any risk of files getting corrupted silently because the servers where your semi-dedicated server account will be created take advantage of a powerful file system called ZFS. Its key advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As we keep 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 saved. If there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because this happens right away, there's no chance that a damaged copy could remain on our servers or that it could be copied to the other hard drives in the RAID. None of the other file systems include this kind of checks and furthermore, even during a file system check following an unexpected electrical power failure, none of them can find silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check obsolete.
