The process of files getting corrupted owing to some hardware or software failure is known as data corruption and this is one of the main problems that web hosting companies face as the larger a hard drive is and the more information is kept on it, the much more likely it is for data to be corrupted. You will find various fail-safes, still often the information becomes corrupted silently, so neither the particular file system, nor the admins notice a thing. As a result, a damaged file will be treated as a regular one and if the hard disk drive is a part of a RAID, that file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in reality the damage will get even worse. Once a file gets damaged, it will be partly or completely unreadable, so a text file will not be readable, an image file will present a random combination of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your site content. Although the most widespread server file systems have various checks, they frequently fail to detect some problem early enough or require a long period of time to be able to check all files and the server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Website Hosting

The integrity of the data that you upload to your new cloud website hosting account shall be guaranteed by the ZFS file system which we employ on our cloud platform. The vast majority of web hosting service providers, like our company, use multiple HDDs to keep content and because the drives work in a RAID, exactly the same information is synchronized between the drives at all times. In case a file on a drive gets damaged for whatever reason, yet, it's likely that it will be copied on the other drives since other file systems do not feature special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the damaged copy will be substituted with a good one from a different hard disk. Since this happens instantly, there's no possibility for any of your files to ever get damaged.
