Data corruption is the damage of info caused by various software or hardware fails. The moment a file gets corrupted, it will no longer work correctly, so an app will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, that makes it a significant problem for website hosting servers as failures are more likely to occur on larger hard drives where significant volumes of info are stored. In case a drive is part of a RAID and the information on it is copied on other drives for redundancy, it is likely that the damaged file will be treated as an ordinary one and will be copied on all drives, making the harm permanent. A lot of the file systems that run on web servers nowadays often are not able to recognize corrupted files in real time or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Cloud Website Hosting
The integrity of the data that you upload to your new cloud website hosting account will be ensured by the ZFS file system which we make use of on our cloud platform. The vast majority of hosting suppliers, including our firm, use multiple HDDs to keep content and since the drives work in a RAID, exactly the same data is synchronized between the drives at all times. In case a file on a drive gets corrupted for reasons unknown, yet, it is likely that it will be reproduced on the other drives since alternative file systems do not include special checks for that. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, and the bad copy shall be replaced with a good one from a different hard disk drive. Since this happens right away, there's no possibility for any of your files to ever be damaged.
