The process of files being corrupted resulting from some hardware or software failure is referred to as data corruption and this is among the main problems that Internet hosting companies face as the larger a hard disk is and the more data is filed on it, the much more likely it is for data to be corrupted. You will find several fail-safes, yet often the information is damaged silently, so neither the file system, nor the admins detect a thing. Thus, a bad file will be treated as a regular one and if the hard disk is a part of a RAID, that file will be copied on all other disk drives. In principle, this is for redundancy, but in practice the damage will get worse. The moment a file gets corrupted, it will be partly or completely unreadable, therefore 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 shall be impossible to unpack, and you risk sacrificing your content. Although the most well-known server file systems have various checks, they frequently fail to find some problem early enough or require a vast time period to be able to check all files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data that you upload to your new cloud hosting account will be ensured by the ZFS file system that we make use of on our cloud platform. Most of the hosting suppliers, 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 all the time. If a file on a drive gets corrupted for whatever reason, however, it's more than likely that it will be copied on the other drives since other file systems do not include special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every single file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the bad copy will be substituted with a good one from a different hard disk. Due to the fact that this happens immediately, there's no possibility for any of your files to ever get damaged.
