Data corruption is the accidental change of a file or the loss of information that often occurs during reading or writing. The reason may be hardware or software malfunction, and for that reason, a file could become partially or completely corrupted, so it will no longer work properly since its bits will be scrambled or lost. An image file, for example, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. In the event that this kind of a problem occurs and it isn't noticed by the system or by an administrator, the data will become corrupted silently and when this happens on a drive which is part of a RAID array where the data is synchronized between different drives, the corrupted file shall be reproduced on all other drives and the damage will be permanent. A number of frequently used file systems either don't have real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a common matter on internet hosting servers where huge volumes of information are kept.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the info uploaded in every single cloud website 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 via a unique checksum for every single file. We shall store your data on multiple NVMe drives that operate in a RAID, so the same files will be present on several places at once. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file is different from what it has to be, the file system swaps that file with an undamaged version from another drive from the RAID. There's no other file system that 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 do not have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you acquire one of our semi-dedicated server plans, you won't need to worry about silent file corruption since we use ZFS - an advanced file system which checks all the files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between multiple NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no danger for any part of your content at any time. By comparison, other file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a bad copy can be replicated on the remaining drives as well and you may lose important info. Because this is not the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
