Data corruption is the accidental modification of a file or the loss of information that usually occurs during reading or writing. The reason may be hardware or software malfunction, and consequently, a file can become partially or fully corrupted, so it'll no longer work correctly since its bits will be scrambled or missing. An image file, for example, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etc. When this kind of a problem appears and it is not found by the system or by an admin, the data will become corrupted silently and if this happens on a drive that is a part of a RAID array where the info is synced between various drives, the corrupted file will be copied on all the other drives and the damage will be permanent. A large number of commonly used file systems either do not offer real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a very common matter on internet hosting servers where substantial amounts of info are kept.
No Data Corruption & Data Integrity in Cloud Website Hosting
We warrant the integrity of the info uploaded in each and every cloud website hosting account which is created on our cloud platform because we use the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption using a unique checksum for each and every file. We'll store your data on a number of NVMe drives which operate in a RAID, so exactly the same files will exist on several places concurrently. 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 needs to be, the file system replaces that file with a healthy version from a different drive from the RAID. No other file system uses checksums, so it is possible for data to become silently corrupted and the bad file to be duplicated on all drives over time, but since this can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you acquire one of our semi-dedicated hosting plans, you won't need to worry about silent data corruption as we use ZFS - an advanced file system that keeps track of all files in real time. Each time 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 synchronized between a couple of NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no risk for any part of your content at any moment. In comparison, all of the other file systems perform checks only after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy can be replicated on the other disks as well and you may lose crucial info. Because this is not the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
