Data corruption is the accidental transformation of a file or the losing of info that usually occurs during reading or writing. The reason can be hardware or software failure, and as a consequence, a file can become partially or completely corrupted, so it'll no longer work properly since its bits will be scrambled or missing. An image file, for example, will no longer display an authentic image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. When this kind of a problem occurs and it isn't found by the system or by an admin, the data will be corrupted silently and in case this happens on a disk drive which is a part of a RAID array where the data is synchronized between different drives, the corrupted file shall be copied on all the other drives and the harm will become long term. Numerous frequently used file systems either do not offer real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a common issue on web hosting servers where huge volumes of data are stored.
No Data Corruption & Data Integrity in Website Hosting
We warrant the integrity of the info uploaded in any website hosting account which is made on our cloud platform because we employ 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 information on multiple 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 files on all drives in real time and if the checksum of any file differs from what it has to be, the file system swaps that file with a healthy copy from a different drive within the RAID. There's no other file system that uses checksums, so it is possible for data to get silently damaged and the bad file to be reproduced 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 data.
