Data corruption is the damage of information due to various hardware or software failures. When a file gets damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file shall be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an admin, which makes it a serious problem for website hosting servers as failures are very likely to happen on larger hard disk drives where significant volumes of information are kept. When a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it is more than likely that the damaged file will be treated as a standard one and will be copied on all drives, making the damage permanent. A huge number of the file systems which operate on web servers nowadays often are unable to locate corrupted files right away or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the information uploaded in each shared hosting account that is made on our cloud platform because we employ the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption through a unique checksum for each file. We shall store your data on a number of NVMe drives that operate in a RAID, so exactly the same files will be available on several places simultaneously. 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 replaces that file with a healthy copy from a different drive within the RAID. There's no other file system which uses checksums, so it's possible for data to get silently corrupted and the bad file to be replicated on all drives with time, but since that can never happen on a server using ZFS, you won't have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you get one of our semi-dedicated server packages, you will not have to worry about silent data corruption as we use ZFS - a high level file system that monitors all files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a couple of 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 when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens instantly, so there will be no risk for any part of your content at any moment. In comparison, alternative file systems perform checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a corrupted copy can be replicated on the remaining drives as well and you can lose precious info. Since this isn't the case with ZFS, we guarantee the integrity of each file you upload no matter what.
