Data corruption is the damage of information because of various software or hardware problems. The moment a file is corrupted, it will no longer work accurately, so an app will not start or shall give errors, a text file shall be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, which makes it a significant problem for hosting servers as failures are very likely to occur on larger in size hard disks where considerable volumes of info are kept. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as an undamaged one and it will be duplicated on all of the drives, making the damage permanent. Lots of the file systems that operate on web servers today often are not able to detect corrupted files instantly or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Shared Web Hosting
We warrant the integrity of the information uploaded in each and every shared web hosting account that is created on our cloud platform because we employ the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption through a unique checksum for each file. We shall store your info on a large number of SSD drives that operate in a RAID, so exactly the same files will exist on several places at once. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged version from another drive in the RAID. There's no other file system which uses checksums, so it is easy for data to be silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server using ZFS, you don't have to worry about the integrity of your information.
