Data corruption is the damage of information due to various software or hardware failures. Once a file gets damaged, it will no longer work properly, so an app will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, which makes it a significant problem for web hosting servers as problems are more likely to occur on larger in size hard drives where significant volumes of information are kept. In case a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as a good one and will be copied on all drives, making the harm permanent. A huge number of the file systems which operate on web servers nowadays often cannot discover corrupted files in real time or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Web Hosting
The integrity of the data that you upload to your new web hosting account shall be guaranteed by the ZFS file system which we use on our cloud platform. The majority of web hosting suppliers, like our company, use multiple hard disks to store content and since the drives work in a RAID, identical info is synchronized between the drives at all times. In case a file on a drive becomes corrupted for whatever reason, however, it's very likely that it will be copied on the other drives since alternative file systems don't offer special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every single file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, and the bad copy shall be swapped with a good one from another hard disk. As this happens immediately, there is no possibility for any of your files to ever get damaged.
