Data corruption is the damage of info because of various hardware or software problems. Once a file gets corrupted, it will no longer function properly, so an application will not start or will give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, which makes it a serious problem for hosting servers as failures are much more likely to happen on larger in size hard drives where considerable volumes of info are placed. When a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's very likely that the damaged file will be treated as a standard one and it'll be duplicated on all drives, making the damage permanent. A huge number of the file systems that operate on web servers today often are not able to discover corrupted files immediately or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Web Hosting

We guarantee the integrity of the information uploaded in any web hosting account which is generated on our cloud platform as we work with the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption via a unique checksum for each and every file. We'll store your information on a large number of NVMe drives that operate in a RAID, so the exact same files will be available on several places at the same time. ZFS checks the digital fingerprint of all files on all of the drives in real time and in case the checksum of any file differs from what it should be, the file system replaces that file with a healthy version from another drive from the RAID. No other file system uses checksums, so it's possible for data to become silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you obtain one of our semi-dedicated hosting packages, you won't have to be concerned about silent data corruption since we use ZFS - a high level file system that monitors all the files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between a number of NVMe drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done right away, so there will be no threat for any part of your content at any moment. In contrast, all the other file systems carry out checks after a system failure, but since they don't use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the rest of the drives as well and you could lose important info. As this isn't the case with ZFS, we guarantee the integrity of each file you upload no matter what.
