The process of files being damaged as a consequence of some hardware or software failure is referred to as data corruption and this is among the main problems which Internet hosting companies face since the larger a hard disk drive is and the more information is stored on it, the more likely it is for data to get corrupted. There're several fail-safes, yet often the information gets damaged silently, so neither the particular file system, nor the admins notice a thing. Thus, a damaged file will be treated as a standard one and if the HDD is a part of a RAID, that file will be copied on all other disk drives. In theory, this is done for redundancy, but in practice the damage will be even worse. Once a given file gets damaged, it will be partly or entirely unreadable, which means that a text file will no longer be readable, an image file will display a random mix of colors if it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your website content. Although the most commonly used server file systems feature various checks, they are likely to fail to find a problem early enough or require an extensive time period to be able to check all files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Web Hosting
We guarantee the integrity of the info uploaded in any cloud web hosting account which is made on our cloud platform since we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption using a unique checksum for each and every file. We'll store your information on multiple NVMe drives which work in a RAID, so the exact same files will exist on several places at the same time. ZFS checks the digital fingerprint of all of the files on all drives in real time and in the event that the checksum of any file differs from what it has to be, the file system swaps that file with a healthy version from another drive from the RAID. No other file system uses checksums, so it is possible for data to get silently corrupted and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your info.
