The process of files being corrupted owing to some hardware or software failure is known as data corruption and this is among the main problems that web hosting companies face because the larger a hard disk drive is and the more information is placed on it, the much more likely it is for data to become corrupted. You can find several fail-safes, but often the info becomes damaged silently, so neither the particular file system, nor the administrators detect anything. Because of this, a damaged file will be handled as a good one and if the hard disk is part of a RAID, the file will be copied on all other disk drives. In theory, this is for redundancy, but in practice the damage will get even worse. When some file gets damaged, it will be partly or completely unreadable, so a text file will not be readable, an image file will present a random mix of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your content. Although the most widely used server file systems have various checks, they quite often fail to find a problem early enough or require an extensive time period to check all of the files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Web Hosting
We guarantee the integrity of the info uploaded in any web hosting account which is made on our cloud platform because we use the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption via a unique checksum for every single file. We shall store your data on multiple SSD drives that function in a RAID, so the same files will be accessible on several places at once. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in case the checksum of any file is different from what it has to be, the file system replaces that file with a healthy version from a different drive within the RAID. There's no other file system that uses checksums, so it is possible for data to be silently corrupted and the bad file to be reproduced on all drives with time, but since this can never happen on a server running 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 risk of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's 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 other drives and the one it has saved. In the event that there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and considering that it happens in real time, there's no chance that a damaged copy can 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 type of checks and what's more, even during a file system check following a sudden power failure, none of them can 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 unneeded.
