The process of files being damaged owing to some hardware or software failure is known as data corruption and this is one of the main problems that hosting companies face since the larger a hard drive is and the more data is kept on it, the much more likely it is for data to get corrupted. There are a couple of fail-safes, still often the information is damaged silently, so neither the particular file system, nor the administrators detect anything. Because of this, a bad file will be treated as a standard one and if the HDD is part of a RAID, that file will be copied on all other drives. In theory, this is for redundancy, but in practice the damage will be even worse. The moment some file gets corrupted, it will be partially or fully unreadable, which means that 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 will be impossible to unpack, and you risk losing your website content. Although the most popular server file systems have various checks, they often fail to detect a problem early enough or require a vast amount of time in order to check all files and the web server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Website Hosting
We warrant the integrity of the data uploaded in each cloud website hosting account that is generated on our cloud platform as we work with 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 info on a large number of SSD drives which operate in a RAID, so the exact same files will exist on several places at once. ZFS checks the digital fingerprint of all of the files on all drives in real time and if the checksum of any file is different from what it should be, the file system swaps that file with an undamaged version from another drive in the RAID. No other file system uses checksums, so it is easy for data to get silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your info.
