Data corruption is the damage of data because of various software or hardware failures. The moment a file gets damaged, it will no longer work correctly, so an app will not start or will give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, which makes it a serious problem for hosting servers as failures are much more likely to happen on bigger hard disk drives where considerable volumes of information are kept. If a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as a standard one and it will be copied on all drives, making the damage permanent. A lot of the file systems that operate on web servers nowadays often are not able to discover corrupted files instantly or they need time-consuming system checks during which the server isn't functioning.
No Data Corruption & Data Integrity in Website Hosting
The integrity of the data which you upload to your new website hosting account shall be ensured by the ZFS file system that we make use of on our cloud platform. The majority of web hosting providers, including our firm, use multiple hard drives to keep content and since the drives work in a RAID, the exact same info is synchronized between the drives all the time. If a file on a drive becomes corrupted for whatever reason, yet, it is very likely that it will be reproduced on the other drives since other file systems do not include special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, so the bad copy shall be swapped with a good one from another disk drive. Since this happens in real time, there is no possibility for any of your files to ever get damaged.
