The process of files being corrupted owing to some hardware or software failure is known as data corruption and this is one of the main problems which Internet hosting companies face because the larger a hard drive is and the more info is kept on it, the much more likely it is for data to get corrupted. You can find different fail-safes, but often the info becomes damaged silently, so neither the particular file system, nor the admins notice a thing. As a result, a damaged file will be handled as a standard one and if the HDD is a part of a RAID, the file will be duplicated on all other drives. Theoretically, this is done for redundancy, but in reality the damage will get even worse. The moment some file gets damaged, it will be partially or completely unreadable, so a text file will no longer be readable, an image file will present a random mix of colors in case it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your site content. Although the most frequently used server file systems have various checks, they quite often fail to detect a problem early enough or require a vast time period in order to check all files and the web server will not be operational in the meantime.
No Data Corruption & Data Integrity in Website Hosting
We guarantee the integrity of the info uploaded in every single website hosting account which is created on our cloud platform as we use the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption through a unique checksum for each and every file. We shall store your data on multiple SSD drives which work in a RAID, so the very same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all drives in real time and in case the checksum of any file differs from what it should be, the file system replaces that file with an undamaged version from another 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 with time, but since this can never happen on a server running ZFS, you will not have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any possibility of files getting damaged silently since the servers where your semi-dedicated hosting account will be created use a powerful file system known as ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. As we keep all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has stored. If there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and considering that this happens right away, there's no chance that a corrupted copy could remain on our web servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems employ this kind of checks and in addition, even during a file system check after an unexpected power failure, none of them will find silently corrupted files. In contrast, ZFS won't crash after a blackout and the regular checksum monitoring makes a time-consuming file system check unneeded.
