The process of files being corrupted as a consequence of some hardware or software failure is referred to as data corruption and this is one of the main problems which Internet hosting companies face since the larger a hard disk is and the more information is placed on it, the much more likely it is for data to get corrupted. You can find different fail-safes, yet often the information is damaged silently, so neither the particular file system, nor the administrators notice anything. Consequently, a bad file will be handled as a standard one and if the hard disk drive is a part of a RAID, the file will be duplicated on all other drives. In theory, this is for redundancy, but in practice the damage will be even worse. When some file gets damaged, it will be partly or fully unreadable, therefore 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 will be impossible to unpack, and you risk losing your content. Although the most well-known server file systems include various checks, they are likely to fail to detect a problem early enough or require a vast amount of time in order to check all the files and the web hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Cloud Web Hosting
The integrity of the data which you upload to your new cloud web hosting account will be ensured by the ZFS file system which we make use of on our cloud platform. The majority of web hosting suppliers, including our firm, use multiple hard drives 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 some reason, however, it is likely that it will be reproduced on the other drives as alternative file systems do not offer special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the damaged copy shall be substituted with a good one from another drive. Due to the fact that this happens instantly, there is no risk for any of your files to ever be damaged.
