Data corruption is the damage of information caused by various software or hardware fails. The moment a file gets damaged, it will no longer function accurately, so an app will not start or shall give errors, a text file will be partially or fully unreadable, an archive will be impossible to open 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 serious problem for website hosting servers as failures are very likely to occur on bigger hard disk drives where large volumes of information are kept. When a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as an undamaged one and will be copied on all drives, making the harm permanent. A lot of the file systems which run on web servers these days often cannot find corrupted files right away or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Hosting

We guarantee the integrity of the info uploaded in each hosting account which is made on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption through a unique checksum for every single file. We will store your info on a large number of NVMe drives that work in a RAID, so the very same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and in case the checksum of any file is different from what it has to be, the file system swaps that file with a healthy version from a different drive in the RAID. No other file system uses checksums, so it is 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 won't have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any chance of files getting corrupted silently due to the fact that the servers where your semi-dedicated server account will be created use a powerful file system named ZFS. Its main advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. As we store all content on multiple NVMe drives, ZFS checks if 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 damaged copy is replaced with a healthy one from one of the other drives and considering that it happens instantly, there's no chance that a corrupted copy could remain on our hosting servers or that it could be duplicated to the other drives in the RAID. None of the other file systems work with this type of checks and furthermore, even during a file system check right after a sudden blackout, none of them will detect silently corrupted files. In comparison, ZFS does not crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unnecessary.
