Data corruption is the unintentional transformation of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software malfunction, and as a consequence, a file could become partially or entirely corrupted, so it will no longer function as it should because its bits shall be scrambled or lacking. An image file, for example, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In the event that this kind of an issue appears and it's not identified by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive which is a part of a RAID array where the information is synchronized between different drives, the corrupted file shall be reproduced on all of the other drives and the damage will be long term. A number of widely used file systems either don't feature real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a common matter on internet hosting servers where huge amounts of data are stored.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the information uploaded in each cloud hosting account which is created on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption thanks to a unique checksum for every single file. We'll store your data on a large number of SSD drives which function in a RAID, so the exact same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in case the checksum of any file is different from what it should be, the file system replaces that file with an undamaged version from a different drive from the RAID. There's no other file system which uses checksums, so it's possible for data to get silently corrupted and the bad file to be duplicated on all drives with time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your data.
