Data corruption is the damage of data caused by various hardware or software fails. When a file is corrupted, it will no longer work accurately, so an app will not start or will give errors, a text file could be partially or completely 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 serious problem for website hosting servers as problems are very likely to happen on bigger hard drives where vast volumes of info are kept. In case a drive is part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as a good one and it'll be copied on all of the drives, making the harm permanent. A huge number of the file systems that operate on web servers nowadays often cannot locate corrupted files right away or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Web Hosting
The integrity of the data which you upload to your new web hosting account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most web hosting suppliers, including our company, use multiple HDDs to keep content and because the drives work in a RAID, identical data is synchronized between the drives all of the time. If a file on a drive becomes damaged for reasons unknown, yet, it's very likely that it will be reproduced on the other drives since other file systems don't have special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the bad copy shall be replaced with a good one from another hard drive. Because this happens immediately, there's no risk for any of your files to ever be corrupted.
