The process of files being damaged due to some hardware or software failure is called data corruption and this is one of the main problems which hosting companies face since the larger a hard disk drive is and the more information is kept on it, the more likely it is for data to be corrupted. You will find different fail-safes, yet often the information is damaged silently, so neither the particular file system, nor the admins detect anything. Thus, a bad file will be treated as a good one and if the hard disk is a part of a RAID, the file will be copied on all other drives. In principle, this is for redundancy, but in practice the damage will be even worse. Once a given file gets corrupted, it will be partially or completely unreadable, therefore a text file will no longer be readable, an image file will display a random combination 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 popular server file systems include various checks, they quite often fail to find some problem early enough or require a long time period in order to check all the files and the hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the information uploaded in any cloud hosting account that is made on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption through a unique checksum for each file. We will store your information on a number of SSD drives which operate in a RAID, so the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file is different from what it has to be, the file system swaps that file with an undamaged copy from another drive inside the RAID. There's no other file system that uses checksums, so it is easy for data to get silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your information.
