The process of files being corrupted resulting from some hardware or software failure is referred to as data corruption and this is among the main problems which web hosting companies face since the larger a hard drive is and the more data is stored on it, the more likely it is for data to get corrupted. You'll find different fail-safes, yet often the info gets corrupted silently, so neither the file system, nor the admins notice anything. As a result, a bad file will be treated as a standard one and if the hard disk is part of a RAID, that particular file will be duplicated on all other drives. In principle, this is for redundancy, but in practice the damage will get worse. The moment a file gets corrupted, it will be partly or entirely unreadable, therefore a text file will no longer be readable, an image file will display a random mix of colors in case it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your website content. Although the most popular server file systems feature various checks, they quite often fail to detect some problem early enough or require a long time period to be able to check all the files and the web hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Shared Website Hosting
We warrant the integrity of the info uploaded in each shared website hosting account which is made on our cloud platform due to the fact that we use the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption via a unique checksum for each file. We'll store your info on a number of SSD drives that function in a RAID, so the exact same files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file is different from what it has to be, the file system swaps that file with a healthy version from another drive within the RAID. There's no other file system that uses checksums, so it's possible for data to get silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any chance of files getting corrupted silently since the servers where your semi-dedicated server account will be created use a powerful file system named ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. Since we store 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 other drives and the one it has stored. In the event that there is a mismatch, the bad copy is replaced with a good one from one of the other drives and considering that it happens right away, there is no chance that a damaged copy can remain on our website hosting servers or that it could be duplicated to the other drives in the RAID. None of the other file systems work with such checks and what is more, even during a file system check following a sudden power loss, none of them can identify 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 unnecessary.
