Data corruption is the damage of info caused by various hardware or software fails. After a file is corrupted, it will no longer work properly, so an application will not start or shall give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, which makes it a significant problem for hosting servers as fails are more likely to happen on larger in size hard disks where substantial volumes of info are located. If a drive is part of a RAID and the data on it is copied on other drives for redundancy, it's more than likely that the damaged file will be treated as a standard one and will be duplicated on all of the drives, making the harm permanent. A huge number of the file systems that operate on web servers nowadays often are unable to recognize corrupted files instantly or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Hosting
The integrity of the data that you upload to your new hosting account shall be guaranteed by the ZFS file system that we use on our cloud platform. Most web hosting providers, like our company, use multiple hard disk drives to store content and since the drives work in a RAID, exactly the same data is synchronized between the drives at all times. When a file on a drive becomes damaged for reasons unknown, yet, it is more than likely that it will be copied on the other drives because other file systems don't have special checks for that. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every single file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, so the damaged copy shall be replaced with a good one from a different drive. Due to the fact that this happens immediately, there's no possibility for any of your files to ever get damaged.
