The process of files being damaged as a result of some hardware or software failure is referred to as data corruption and this is one of the main problems that Internet hosting companies face as the larger a hard drive is and the more information is placed on it, the much more likely it is for data to be corrupted. You can find a couple of fail-safes, still often the information gets damaged silently, so neither the file system, nor the administrators notice anything. As a result, a bad file will be treated as a regular one and if the hard disk drive is a part of a RAID, the file will be copied on all other drives. Theoretically, this is for redundancy, but in reality the damage will be worse. Once a file gets corrupted, it will be partially or fully unreadable, therefore a text file will not be readable, an image file will show a random blend of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your site content. Although the most popular server file systems feature various checks, they frequently fail to identify some problem early enough or require an extensive amount of time to be able to check all files and the server will not be operational for the time being.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the data uploaded in every cloud hosting account which is made on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption via a unique checksum for every single file. We shall store your information on a number of SSD drives that operate in a RAID, so the exact same files will be accessible on several places at once. ZFS checks the digital fingerprint of all the files on all of the drives in real time and if the checksum of any file differs from what it has to be, the file system replaces that file with a healthy copy from a different drive within the RAID. There's no other file system which uses checksums, so it is possible for data to become silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your info.
