The process of files being corrupted owing to some hardware or software failure is referred to as data corruption and this is one of the main problems which hosting companies face since the larger a hard disk is and the more information is stored on it, the more likely it is for data to get corrupted. There're various fail-safes, but often the information gets corrupted silently, so neither the particular file system, nor the admins detect a thing. Consequently, a corrupted file will be handled as a regular one and if the HDD is a part of a RAID, that file will be duplicated on all other disk drives. Theoretically, this is done for redundancy, but in reality the damage will get even worse. The moment a given file gets damaged, it will be partly or fully unreadable, which means that a text file will not be readable, an image file will display a random blend of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your content. Although the most commonly used server file systems have various checks, they quite often fail to identify a problem early enough or require a vast time period in order to check all of the files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Website Hosting

We warrant the integrity of the information uploaded in every single website hosting account that is made on our cloud platform because we employ the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption using a unique checksum for each and every file. We will store your data on a large number of SSD drives which function in a RAID, so the exact same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file is different from what it should be, the file system swaps that file with a healthy version from another drive in the RAID. There's no other file system which uses checksums, so it's easy for data to become silently corrupted and the bad file to be reproduced on all drives over time, but since that can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any risk of files getting damaged silently because the servers where your semi-dedicated server account will be created use a powerful file system known as ZFS. Its advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint which is 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 corresponds to the one on the other drives and the one it has stored. In the event that there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it 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 drives in the RAID. None of the other file systems use such checks and furthermore, even during a file system check after a sudden electrical power failure, none of them will discover silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the regular checksum monitoring makes a lenghty file system check unneeded.
