Data corruption is the damage of information due to various software or hardware fails. Once a file gets damaged, it will no longer work properly, so an app will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, which makes it a significant problem for hosting servers as fails are much more likely to occur on larger hard disk drives where large volumes of info are located. If a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as a healthy one and it'll be duplicated on all the drives, making the harm permanent. A lot of the file systems that run on web servers today often are not able to recognize corrupted files in real time or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Web Hosting

In case you host your Internet sites in a web hosting account with our firm, you don't need to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform employs the state-of-the-art ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. All of the information that you upload will be stored in a RAID i.e. simultaneously on many different NVMe drives. All of the file systems synchronize the files between the different drives using such a setup, but there's no real guarantee that a file won't be corrupted. This can occur at the time of the writing process on any drive and after that a damaged copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives live and in case a corrupted file is identified, it is substituted with a good copy with the correct checksum from some other drive. By doing this, your info will continue to be intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you get one of our semi-dedicated hosting solutions, you won't have to be concerned about silent data corruption because we use ZFS - an advanced file system which keeps track of all of the files in real time. Every time you upload a file to your web 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 one drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This happens immediately, so there will be no threat for any part of your content at any moment. In comparison, alternative file systems carry out checks only after a system failure, 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 may lose critical data. Because this isn't the case with ZFS, we warrant the integrity of every single file you upload no matter what.
