Data corruption is the unintentional modification of a file or the losing of info which often occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file may become partially or completely corrupted, so it'll no longer function as it should as its bits shall be scrambled or lacking. An image file, for example, will no longer present an actual image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. In the event that this kind of a problem occurs and it is not recognized by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that's part of a RAID array where the information is synchronized between various drives, the corrupted file shall be reproduced on all the other drives and the damage will be long term. Many widespread file systems either do not offer real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a very common matter on hosting servers where large volumes of information are stored.

No Data Corruption & Data Integrity in Web Hosting

We have resolved the matter of silent data corruption on all our web hosting servers by using the advanced Z file system, or ZFS. The latter is superior to other file systems since it is the only one on the market that checks all the files instantly by employing a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it'll be stored on several NVMe drives and frequently synced between them for redundancy. ZFS constantly analyzes the checksum of all files and if any file is detected as damaged, it is replaced instantly with a good copy from another disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the other NVMes. ZFS requires plenty of physical memory in order to carry out the real-time checks and the benefit of our cloud website hosting platform is that we use multiple powerful servers working together. In case you host your websites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you go for one of our semi-dedicated server plans, you won't need to worry about silent file corruption as we use ZFS - a high level file system that keeps track of all of the 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. The file will be synced between a couple of 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 in case it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no danger for any part of your content at any time. In comparison, all of the other file systems carry out checks after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a bad copy can be replicated on the other drives as well and you could lose crucial info. Since this is not the case with ZFS, we warrant the integrity of each file you upload no matter what.
