Data corruption is the damage of information because of various software or hardware fails. After a file gets damaged, it will no longer work correctly, so an application will not start or shall 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 damaged without any identification by the system or an admin, which makes it a serious problem for website hosting servers as problems are more likely to happen on larger hard drives where significant volumes of information are kept. In case a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as a regular one and will be copied on all the drives, making the harm permanent. Lots of the file systems that run on web servers these days often cannot find corrupted files right away or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account will be ensured by the ZFS file system that we employ on our cloud platform. The vast majority of internet hosting suppliers, like our company, use multiple hard disks to keep content and since the drives work in a RAID, identical info is synchronized between the drives at all times. When a file on a drive becomes damaged for reasons unknown, however, it's very likely that it will be copied on the other drives because alternative file systems don't have special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each and every file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, which means that the bad copy shall be replaced with a good one from a different hard disk. As this happens instantly, there is no risk for any of your files to ever be damaged.
