The process of files getting corrupted resulting from some hardware or software failure is known as data corruption and this is among the main problems which hosting companies face as the larger a hard disk is and the more info is placed on it, the more likely it is for data to get corrupted. You'll find various fail-safes, still often the data becomes damaged silently, so neither the file system, nor the admins notice anything. Because of this, a corrupted file will be handled as a good one and if the HDD is a part of a RAID, the file will be copied on all other drives. In theory, this is done for redundancy, but in practice the damage will be worse. Once some file gets corrupted, it will be partly or fully unreadable, therefore a text file will not be readable, an image file will present a random blend of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your site content. Although the most frequently used server file systems include various checks, they quite often fail to discover a problem early enough or require a vast amount of time to be able to check all of the files and the hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Cloud Hosting
We warrant the integrity of the information uploaded in every single cloud hosting account that is made on our cloud platform as we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption via a unique checksum for each file. We will store your data on multiple SSD drives that operate in a RAID, so the same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all files on all drives in real time and if the checksum of any file differs from what it should be, the file system swaps that file with an undamaged copy from a different drive in the RAID. There's no other file system which uses checksums, so it is easy for data to become silently damaged 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 information.
