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 information is stored on it, the more likely it is for data to get corrupted. There're various fail-safes, still often the data gets damaged silently, so neither the file system, nor the administrators detect anything. As a result, a bad file will be handled as a standard one and if the hard drive is a 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. Once some file gets damaged, it will be partly or fully unreadable, which means that a text file will not be readable, an image file will display a random blend of colors if it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your content. Although the most well-known server file systems include various checks, they are likely to fail to find a problem early enough or require an extensive period of time to check all the files and the web hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Website Hosting
We warrant the integrity of the data uploaded in any website hosting account that is generated on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption through a unique checksum for each file. We shall store your info on a number of SSD drives that operate in a RAID, so exactly the same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and in case the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from another drive inside the RAID. No other file system uses checksums, so it's easy for data to be silently damaged and the bad file to be replicated 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 data.
