The process of files being corrupted because of some hardware or software failure is called data corruption and this is among the main problems that hosting companies face as the larger a hard disk drive is and the more data is placed on it, the much more likely it is for data to get corrupted. There are several fail-safes, still often the information gets corrupted silently, so neither the particular file system, nor the administrators detect a thing. Thus, a damaged file will be handled as a good one and if the HDD is a part of a RAID, the file will be copied on all other disk drives. In theory, this is for redundancy, but in practice the damage will get even worse. When a file gets corrupted, it will be partly or fully unreadable, which means that a text file will no longer be readable, an image file will display a random blend of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your content. Although the most well-known server file systems feature various checks, they are likely to fail to find some problem early enough or require a long time period to check all the files and the web hosting server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data that you upload to your new shared hosting account will be ensured by the ZFS file system that we take advantage of on our cloud platform. Most of the internet hosting service providers, like our firm, use multiple hard drives to keep content and since the drives work in a RAID, the same data is synchronized between the drives all the time. If a file on a drive becomes corrupted for some reason, yet, it's very likely that it will be reproduced on the other drives since alternative file systems don't have special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the damaged copy shall be substituted with a good one from another hard disk. As this happens immediately, there is no risk for any of your files to ever get corrupted.
