The process of files being corrupted because of some hardware or software failure is known as data corruption and this is one of the main problems which Internet hosting companies face since the larger a hard disk drive is and the more data is kept on it, the more likely it is for data to be corrupted. There're a couple of fail-safes, still often the info gets damaged silently, so neither the file system, nor the administrators notice a thing. Thus, a damaged file will be treated as a standard one and if the HDD is part of a RAID, the file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will be worse. When a given file gets damaged, it will be partly or entirely unreadable, which means that a text file will not 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 widely used server file systems have various checks, they quite often fail to identify some problem early enough or require a vast period of time in order to check all of the files and the server will not be operational for the time being.

No Data Corruption & Data Integrity in Web Hosting

The integrity of the data which you upload to your new web hosting account shall be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most of the web hosting suppliers, like our firm, use multiple hard disks to store content and because the drives work in a RAID, the exact same data is synchronized between the drives all the time. If a file on a drive becomes corrupted for whatever reason, however, it is more than likely that it will be reproduced on the other drives as alternative file systems do not offer special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, so the bad copy shall be swapped with a good one from another hard disk. Since this happens immediately, there's no risk for any of your files to ever get corrupted.
