Data corruption is the damage of data due to various hardware or software problems. The moment a file is damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file will be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as failures are much more likely to happen on larger in size hard drives where significant volumes of information are located. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's very likely that the damaged file will be treated as a healthy one and it'll be duplicated on all drives, making the damage permanent. A lot of the file systems which run on web servers these days often cannot discover corrupted files instantly or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data which you upload to your new shared web hosting account shall be guaranteed by the ZFS file system that we work with on our cloud platform. Most of the web hosting suppliers, including our firm, use multiple HDDs to store content and because the drives work in a RAID, the same information is synchronized between the drives at all times. If a file on a drive is corrupted for some reason, yet, it is likely that it will be duplicated on the other drives since alternative file systems do not include special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the damaged copy will be swapped with a good one from another disk drive. As this happens immediately, there is no risk for any of your files to ever be damaged.
