Data corruption is the accidental change of a file or the losing of information which often occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file could become partially or fully corrupted, so it will no longer work correctly since its bits shall be scrambled or lost. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. When this kind of an issue occurs and it isn't recognized by the system or by an admin, the data will get corrupted silently and in case this happens on a disk drive that is a part of a RAID array where the info is synced between different drives, the corrupted file will be duplicated on all of the other drives and the harm will be permanent. Many frequently used file systems either do not offer real-time checks or don't have high quality ones that will detect an issue before the damage is done, so silent data corruption is a very common issue on hosting servers where huge amounts of information are kept.
No Data Corruption & Data Integrity in Cloud Hosting
We warrant the integrity of the info uploaded in each and every cloud 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 that was designed to avoid silent data corruption using a unique checksum for every single file. We shall store your info on multiple SSD drives that operate in a RAID, so the exact same files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all the 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 a different drive within the RAID. No other file system uses checksums, so it is easy for data to get silently corrupted and the bad file to be replicated on all drives with time, but since this can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your data.
