Data corruption is the accidental modification of a file or the loss of info that often occurs during reading or writing. The reason may be hardware or software malfunction, and for that reason, a file may become partially or fully corrupted, so it will no longer function as it should because its bits will be scrambled or missing. 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 since its content will be unreadable, etcetera. If such a problem occurs and it isn't noticed by the system or by an administrator, the data will be corrupted silently and if this happens on a drive that is part of a RAID array where the information is synchronized between various different drives, the corrupted file will be reproduced on all the other drives and the damage will be permanent. Many widespread file systems either do not feature 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 common matter on internet hosting servers where substantial amounts of information are stored.

No Data Corruption & Data Integrity in Website Hosting

We guarantee the integrity of the information uploaded in each and every website hosting account that is generated on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption through a unique checksum for each and every file. We shall store your information on a large number of NVMe drives which function in a RAID, so identical files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all of the files on all of 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 version from another drive in the RAID. There's no other file system which uses checksums, so it's easy for data to become silently damaged and the bad file to be duplicated on all drives with time, but since that can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your info.
