Data corruption is the damage of info caused by various software or hardware problems. The moment a file gets damaged, it will no longer function as it should, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive 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 admin, that makes it a significant problem for hosting servers as problems are more likely to happen on bigger hard disks where considerable volumes of information are located. In case a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's 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. Lots of the file systems that operate on web servers these days often are not able to detect corrupted files in real time or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Cloud Website Hosting

We guarantee the integrity of the data uploaded in any cloud website hosting account which is created on our cloud platform as we use the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption via a unique checksum for each and every file. We will store your information on multiple NVMe drives that function in a RAID, so the same files will be accessible on several places at once. ZFS checks the digital fingerprint of all files on all the drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system swaps that file with an undamaged version from another drive within the RAID. There's no other file system which uses checksums, so it's easy for data to become silently corrupted and the bad file to be replicated on all drives with time, but since this can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any probability of files getting damaged silently because the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its main advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. Since we store all content on numerous NVMe drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. If there is a mismatch, the bad copy is replaced with a good one from one of the other drives and considering that it happens instantly, there is no chance that a corrupted copy can remain on our website hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems include such checks and what is more, even during a file system check after an unexpected power failure, none of them will detect silently corrupted files. In comparison, ZFS won't crash after a power loss and the regular checksum monitoring makes a time-consuming file system check unnecessary.
