Data corruption is the damage of info because of various software or hardware failures. Once a file gets corrupted, it will no longer work properly, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as problems are more likely to occur on larger in size hard drives where large volumes of info are located. 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 will be copied on all of the drives, making the damage permanent. A huge number of the file systems which run on web servers today often cannot detect corrupted files instantly or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Website Hosting
We warrant the integrity of the data uploaded in any website hosting account that is generated on our cloud platform since we work with the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption using a unique checksum for every single file. We'll store your info on a number of SSD drives that work in a RAID, so exactly the same files will exist on several places at once. ZFS checks the digital fingerprint of all of the files on all the drives in real time and if the checksum of any file is different from what it needs to be, the file system swaps that file with a healthy version from another drive from the RAID. No other file system uses checksums, so it's possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you do not have to worry about the integrity of your info.
