Data corruption is the damage of info due to various software or hardware problems. Once a file is corrupted, it will no longer work correctly, so an application will not start or shall give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as fails are very likely to occur on bigger hard drives where vast volumes of info are kept. If a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as an ordinary one and will be copied on all the drives, making the harm permanent. A lot of the file systems which operate on web servers today often are not able to detect corrupted files instantly or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Cloud Web Hosting
The integrity of the data that you upload to your new cloud web hosting account shall be ensured by the ZFS file system that we take advantage of on our cloud platform. Most of the web hosting providers, like our company, use multiple hard disks to keep content and because the drives work in a RAID, the same data is synchronized between the drives at all times. In case a file on a drive gets damaged for some reason, yet, it is more than likely that it will be copied on the other drives as other file systems do not offer special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, so the bad copy shall be replaced with a good one from another drive. Because this happens right away, there's no possibility for any of your files to ever be corrupted.
