Data corruption is the damage of information caused by various software or hardware problems. The moment a file is damaged, it will no longer work correctly, so an application will not start or will give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for hosting servers as fails are much more likely to happen on larger in size hard disk drives where significant volumes of info are placed. If a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as an undamaged one and it will be copied on all the drives, making the harm permanent. A lot of the file systems that run on web servers today often cannot find corrupted files right away or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data that you upload to your new shared hosting account shall be guaranteed by the ZFS file system that we employ on our cloud platform. Most of the hosting suppliers, including our firm, use multiple hard disk drives to keep content and since the drives work in a RAID, the exact same data is synchronized between the drives all the time. In case a file on a drive is damaged for whatever reason, however, it's more than likely that it will be duplicated on the other drives because alternative file systems do not offer special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, so the damaged copy will be replaced with a good one from another hard drive. As this happens right away, there's no possibility for any of your files to ever be corrupted.
