The process of files getting corrupted because of some hardware or software failure is known as data corruption and this is one of the main problems which web hosting companies face since the larger a hard disk is and the more data is kept on it, the more likely it is for data to get corrupted. You'll find various fail-safes, but often the info gets damaged silently, so neither the file system, nor the administrators see anything. Thus, a corrupted file will be handled as a regular one and if the hard disk drive is part of a RAID, the file will be duplicated on all other drives. Theoretically, this is for redundancy, but in reality the damage will get worse. The moment some file gets corrupted, it will be partially or completely unreadable, therefore a text file will not be readable, an image file will show a random mix of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your site content. Although the most frequently used server file systems include various checks, they are likely to fail to identify some problem early enough or require a vast period of time to be able to check all files and the hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Web Hosting
We guarantee the integrity of the information uploaded in every single cloud web hosting account that is created on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption using a unique checksum for every single file. We shall store your info on a number of SSD drives which operate in a RAID, so the exact same files will be available on several places concurrently. ZFS checks the digital fingerprint of all files on all drives in real time and if the checksum of any file is different from what it has to be, the file system replaces that file with an undamaged version from some other drive in the RAID. There's no other file system which uses checksums, so it's easy for data to be silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server running ZFS, you do not have to worry about the integrity of your info.
