No Data Corruption & Data Integrity
Learn what ‘No Data Corruption & Data Integrity’ suggests for the info as part of your web hosting account.
Data corruption is the accidental change of a file or the losing of info which usually occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file can become partially or entirely corrupted, so it will no longer work as it should since its bits will be scrambled or missing. An image file, for instance, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In case this kind of a problem occurs and it is not recognized by the system or by an administrator, the data will be corrupted silently and in case this happens on a drive that's a part of a RAID array where the information is synchronized between different drives, the corrupted file shall be reproduced on all other drives and the harm will become permanent. A number of commonly used file systems either do not offer real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a rather common matter on web hosting servers where huge amounts of information are kept.
No Data Corruption & Data Integrity in Web Hosting
We warrant the integrity of the information uploaded in each and every web hosting account that is created on our cloud platform since we work with the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption using a unique checksum for every single file. We shall store your information on a number of SSD drives which function in a RAID, so identical files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and in the event that the checksum of any file is different from what it has to be, the file system swaps that file with a healthy version from a different drive from the RAID. There's no other file system which uses checksums, so it is possible for data to be silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server running ZFS, you do not have to concern yourself with the integrity of your information.
