The process of files getting damaged because of some hardware or software failure is known as data corruption and this is among the main problems which hosting companies face as the larger a hard disk drive is and the more data is placed on it, the much more likely it is for data to become corrupted. You'll find different fail-safes, but often the information is damaged silently, so neither the file system, nor the admins detect a thing. Consequently, a bad file will be treated as a standard one and if the hard disk is part of a RAID, the file will be duplicated on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will be worse. Once 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 sacrificing your website content. Although the most widespread server file systems have various checks, they frequently fail to discover a problem early enough or require a long time period to check all the files and the server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Web Hosting

We guarantee the integrity of the information uploaded in every shared web hosting account which is created on our cloud platform as we use the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption through a unique checksum for each file. We'll store your information on a number of SSD drives which operate in a RAID, so the very same files will be present on several places at once. ZFS checks the digital fingerprint of all the files on all drives in real time and in case the checksum of any file is different from what it needs to be, the file system replaces that file with a healthy copy from another drive inside the RAID. No other file system uses checksums, so it is easy for data to get silently corrupted and the bad file to be replicated on all drives over time, but since this can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any probability of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created take advantage of a powerful file system called ZFS. Its main advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we store all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. If there's a mismatch, the bad copy is replaced with a good one from one of the other drives and since this happens right away, there's no chance that a damaged copy could remain on our servers or that it can be copied to the other hard disks in the RAID. None of the other file systems use this type of checks and furthermore, even during a file system check after a sudden power loss, none of them will discover silently corrupted files. In contrast, ZFS doesn't crash after an electrical power failure and the continual checksum monitoring makes a time-consuming file system check obsolete.
