Data corruption is the unintentional transformation of a file or the loss of information that usually occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file could become partially or fully corrupted, so it will no longer function correctly as its bits shall be scrambled or missing. An image file, for example, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In the event that this kind of a problem appears and it's not noticed by the system or by an admin, the data will get corrupted silently and if this happens on a drive that's a part of a RAID array where the information is synced between various drives, the corrupted file shall be reproduced on all the other drives and the damage will become long term. Many popular file systems either don't feature real-time checks or don't have high quality ones that will detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where substantial amounts of information are stored.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the info uploaded in every shared hosting account that is generated on our cloud platform as we use the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption thanks to a unique checksum for each and every file. We'll store your info on a large number of SSD drives which function in a RAID, so the very same files will be available on several places at the same time. ZFS checks the digital fingerprint of all of the files on all drives in real time and in the event that the checksum of any file is different from what it should be, the file system swaps that file with an undamaged copy from another drive within the RAID. There's no other file system which uses checksums, so it is easy for data to get silently corrupted and the bad file to be duplicated on all drives over time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your information.
