Data corruption is the unintended change of a file or the loss of info that usually occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file may become partially or entirely corrupted, so it'll no longer function correctly as its bits shall be scrambled or lost. An image file, for instance, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In case such an issue occurs and it is not noticed by the system or by an admin, the data will become corrupted silently and if this happens on a drive that is part of a RAID array where the information is synchronized between various drives, the corrupted file shall be copied on all the other drives and the harm will be long term. Numerous popular file systems either do not offer real-time checks or don't have good ones that will detect a problem before the damage is done, so silent data corruption is a rather common matter on hosting servers where large volumes of data are stored.
No Data Corruption & Data Integrity in Cloud Hosting
We warrant the integrity of the information uploaded in every single cloud hosting account that is created on our cloud platform as we work with the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption through a unique checksum for each file. We shall store your info on multiple SSD drives that work in a RAID, so exactly the same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all the drives in real time and if the checksum of any file differs from what it should be, the file system replaces that file with an undamaged version from another drive from the RAID. There's no other file system which uses checksums, so it's possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you won't have to worry about the integrity of your information.
