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 because of this, a file could become partially or entirely corrupted, so it will no longer work properly since its bits shall be scrambled or lost. An image file, for example, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. If this kind of a problem occurs and it isn't recognized by the system or by an administrator, the data will become corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the data is synchronized between different drives, the corrupted file shall be copied on all of the other drives and the damage will be permanent. Many widespread file systems either don't offer real-time checks or don't have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where large amounts of information are stored.

No Data Corruption & Data Integrity in Cloud Web Hosting

We warrant the integrity of the data uploaded in each and every cloud web hosting account that is made on our cloud platform as we employ the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption via a unique checksum for each file. We will store your data on a large number of SSD drives that operate in a RAID, so the same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file differs from what it has to be, the file system replaces that file with an undamaged copy from another drive within the RAID. There's no other file system which uses checksums, so it's possible for data to become silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your data.
