Data corruption is the damage of data due to various hardware or software failures. Once a file gets damaged, it will no longer work accurately, 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 unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as failures are very likely to happen on larger in size hard disk drives where large volumes of info are kept. If a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it is very likely that the damaged file will be treated as a healthy one and it'll be copied on all the drives, making the harm permanent. A lot of the file systems which run on web servers these days often cannot identify 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

We warrant the integrity of the info uploaded in any web hosting account which is generated on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption through a unique checksum for each file. We shall store your data on a number of NVMe drives which operate in a RAID, so exactly the same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in case the checksum of any file is different from what it should be, the file system swaps that file with a healthy version from a different drive from the RAID. There's no other file system that uses checksums, so it's easy for data to be silently damaged and the bad file to be reproduced on all drives over time, but since this 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

We've avoided any chance of files getting damaged silently because the servers where your semi-dedicated hosting account will be created work with a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. As we save all content on numerous NVMe drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. When there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and considering that it happens in real time, there's no chance that a damaged copy can remain on our servers or that it could be duplicated to the other drives 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 electrical power failure, none of them can find silently corrupted files. In comparison, ZFS doesn't crash after a blackout and the continual checksum monitoring makes a lenghty file system check obsolete.
