Data corruption is the unintended modification of a file or the loss of information that often occurs during reading or writing. The reason could be hardware or software failure, and due to this fact, a file can become partially or fully corrupted, so it'll no longer work correctly because its bits shall be scrambled or missing. An image file, for instance, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In case such a problem appears and it's not noticed by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive which is part of a RAID array where the data is synced between various different drives, the corrupted file shall be replicated on all other drives and the harm will become permanent. A number of widespread file systems either do not offer real-time checks or don't have high quality ones which can detect a problem before the damage is done, so silent data corruption is a common problem on web hosting servers where huge amounts of information are kept.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the info uploaded in each shared hosting account that is created on our cloud platform due to the fact that we work with the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption through a unique checksum for every single file. We'll store your info on multiple SSD drives which function in a RAID, so identical files will be present on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from another drive from the RAID. There's no other file system that uses checksums, so it is easy for data to be silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your data.
